Breast Lumps in Boys

Parents are concerned when they find breast lumps in boys. They hope it’s normal, but underneath lies a common fear–it might be a tumor!

Dr. Greene’s Answer:

Lumps of one kind or another are a common reason for a visit to the doctor’s office. The lump might be in the neck (that the parents suspect is just a swollen gland), in the knee (that the parents think is from sliding into third base last month), or under the nipple (that the parents hope is due to puberty). I often enjoy seeing parents with these concerns in my own office. Sometimes the parents feel that they shouldn’t even bother their doctor with this because it’s probably normal. But underneath these hopeful, at-home diagnoses lies a common fear for breast lumps in boys–it might be a tumor!

Most lumps in children are not cancerous and are not serious. Thankfully, childhood cancer is uncommon. But parents’ and boys’ fears are not unfounded. Childhood breast cancer is quite rare, but it certainly does occur, even in boys. In the US breast cancer in males accounts for less than 1% of all cases. But if it is your son, any chance of cancer seems too much. And a lump might be the first sign noticed.

Breast lumps in children often give rise to two immediate fears–Could it be a tumor? Or could something be going wrong with puberty? (A third fear–Will my child be teased?–arises if the first two turn out to be no problem.)

When to be Concerned about Breast Lumps in Boys & When to Relax

I’ll give you some guidelines for when to be concerned about a breast lump and when you can relax.

Puberty is a time of dramatic changes in the body, especially in the reproductive system. These transformations are brought about by surges of complex and precisely balanced hormones. The last time your 12-year-old had these tides of hormones was when he was a newborn–but then the hormones were yours. Coursing through his blood, your hormones matured his lungs, made him ready for life in the big outside world, and along the way may have given him baby acne and breast enlargement–even nipples that leaked milk. This precious newborn season was gone in a blink, but now your 12-year-old son is making surges of these same hormones, which can cause many of those same effects!

There are five stages of the changes that occur during puberty, called Tanner stages or Sexual Maturity Rating (SMR) stages. Breast lumps in boys are common during SMR 3 and SMR 4.

In boys, SMR 3 usually begins at about age 12 or 13 years and lasts a year or so, although it can be normal in our culture to begin as early as 10 years or as late as 14.9 years. SMR 3 is the time when the testes get clearly larger, the penis gets noticeably longer (then thicker in SMR 4), and the pubic hair (though still small in amount) gets darker and starts to curl.

Sperm is first produced during SMR 3.

Boys grow at their fastest during SMR 3 and SMR 4 (girls get their growth spurts earlier). With your son, you’re probably seeing him outgrow his beginning-of-the-year school clothes already–especially his shoes. During SMR 3, the feet and hands usually grow first, then the arms and legs, and finally the trunk–giving them that adorable adolescent gawky look (don’t tell my 12-year-old son I said that).

SMR 3 also marks the beginning of significant underarm perspiration (the odor, as you’ve probably noticed, can start much earlier).

And teenage acne usually begins at SMR 3, continuing on until the end of puberty.

In newborns, baby acne and breast buds often occur at about the same time. In the same way, many adolescent boys develop gynecomastia–true mammary breast tissue in a male–during SMR 3, around age 13 years. This is caused by a relative imbalance of estrogen to testosterone (typical of this stage of puberty).  This imbalance can cause a growth of the breast tissue. The firm lump may occur under only one nipple, or under both nipples, and it is commonly asymmetric. . The lumps are often tender when they are growing the fastest. In at least 90% of kids, these will go away on their own. They may disappear as quickly as in a few months, but it is not unusual for them to last up to 2 years.  By age 17, only 10% of boys will continue to have persistent gynecomastia, which is generally not a problem. . Gynecomastia occurs in up to 69% of boys during puberty and the incidence decreases in the older teenage years.  

Gynecomastia will resolve on its own, but it can be a bit tender.  In general the tenderness is not significant enough to need medication or treatment. It is fine to use warm compresses on the area if that helps.  Sometimes teens will like to wear a compression tank top which can help with tenderness and also with appearance if they are self conscious. 

Gynecomastia can run in families, and when it does, the disappearance pattern tends to be similar in the family. Gynecomastia can happen in boys of all sizes, however it may be more noticeable in those struggling with obesity.  Fatty tissue can also give the appearance of gynecomastia but in this case ensuring daily physical activity and good nutrition will help resolve this problem.  

Times to Worry about Breast Lumps in Boys (Not a Newborn)

  • If they begin before age 10 years or after age 15 years (especially after puberty is complete)
  • If they are not directly under the nipple
  • If there is overlying dimpling of the skin, skin ulceration, or change in the color of the skin
  • If they feel fixed to the skin
  • If they are large–over 1.5 inches (4 cm) in diameter
  • If they don’t go away within 2 years
  • If the nipples leak milk, blood, pus, or other fluid
  • If there are other signs of disease–night sweats, fever, or weight loss, for example

These are all situations in which a breast lump should definitely be examined, in addition to the important regularly scheduled physicals during the puberty years, children should have a careful physical examination right away. Pathologic gynecomastia is very uncommon in adolescents,  but it can occur and does require prompt evaluation, generally by an endocrinologist.  Abnormal gynecomastia is most often related to conditions where there is an excess of estrogen (either from internal or external sources) 

In a study at Johns Hopkins University of 60 high-risk boys with large lumps (> 4 cm), most of the boys–45 of them–turned out to be fine, but 15 did have significant medical problems, including one who had serious cancer. Most of the problems were genetic (such as Klinefelter’s syndrome–XXY boys) or hormonal problems that needed to be treated. Gynecomastia can come from liver disease, testicular disease, or neurologic diseases as well.  Gynecomastia can also be a side effect of taking steroids or other medications. 

If a breast lump is associated with any signs of infection, such as sudden increased size, warmth, tenderness, drainage, redness, or fevers, a visit to your pediatrician is also in order.  These types of infections are most often treated with antibiotics.

If you are ever unsure whether a breast lump is normal, it is always wise to seek the advice and opinion of your child’s doctor.

Good Breast Health Practices for Teens

  • Avoiding steroid supplements
  • Avoiding steroid medicines where possible (e.g., keep asthma well controlled with preventive measures)
  • Avoiding cigarette smoking and exposure to second-hand smoke
  • Avoiding alcohol
  • Being physically active daily (exercise)
  • Eating a healthy, whole-food diet
  • Maintaining ideal weight
  • Avoiding piercing and tattooing in the nipple area

If normal, benign gynecomastia is bothersome, either because it is large or because it doesn’t go away as puberty progresses, treatment is possible. The data on medication treatment in adolescents is small, and currently somewhat inconclusive, as to how significantly medication changes the natural outcome (regression) of the gynecomastia.  Therefore medications are not typically recommended and are not FDA approved at this time for this condition. . . However, in persistent pubertal gynecomastia, surgery to remove, the mammary breast tissue can be pursued. A tiny incision is made under the armpit, and the tissue is removed with a fiberoptic scope. The results are great, and the scar is small and inconspicuous.

Normal, small gynecomastia is yet another reminder of the wonderful changes in your son’s body as he becomes a man. While teenagers can be quite trying to live with at times, savor every moment you can as you enter the last few years of having your son in your home.

    Absolutely brilliant. I found out about my 11-year-old son’s lump yesterday. Although after reading this I’m convinced it is just puberty. I’ll still be making an appointment to see his GP on Monday. Information from Dr. Greene is professional, caring, easy to understand and it covered all the questions that I had in my mind, which kept me awake tonight. It wasn’t just facts that were provided it had a parent view which had a somewhat comforting effect. Thank you so much, I think I can get some sleep now.

    Thank you. I’m a 21 year old male and I’ve had a lump in my right nipple since I was about 10 years old. It has never hurt when touched or squeezed and has been rather slowly decreasing in size and thickness over the years. When I was younger, I was told by family that it was a part of puberty and would go away eventually. I’ve never been to doctor for it specifically, but on a recent checkup I asked about it and was also told it should go down with time.

    I only started looking up more information after feeling a pain in the right side of my chest though not emitted from the lump. I do hope it completely disappears soon without complication.

    Thank you so much for the extensive detail associated with tender lumps directly underneath a young boy’s nipple area. Me & my 12 yr old son feel so much better after reading this informative article. As of this time we are both pretty sure that his one tender knot directly underneath his nipple area is just an average part of growing up. Thank you for the knowledge and preventing us from overreacting and yes we are aware that we are still advised to continue to monitor the size and duration of this lump. But again- thank you for the expert medical advice without having to waste time (ours & the doctor ‘s)

    • Kareem,

      Per Dr. Greene’s recommendations for lumps in boys that last longer than 2 years: “[these] breast lump[s] should definitely be examined, in addition to the important regularly scheduled physicals during the puberty years. These children should have a careful physical examination right away. They should probably have an endocrinology (hormone) workup and perhaps an ultrasound or a mammogram, depending on the exam.” Treatment will be based on the findings of the exam. Surgery may or may not be the best course of action.

      I hope that helps.

    Dr Greene, please my 14 yr old boy is always sad. Why? this is because his left breast is growing big and his friends call him names. It saddens me to see my son going through such pains. Please what should I do?

    Added:
    • Hi Victor,

      How tough for your son — and for you to see him so sad.

      Have you taken him to a doctor? If so did the doctor say this is normal and transitory? That would be the best news because it means the breast size will resolve on its own and no treatment is needed. At this point, your son’s biggest problem is facing his peers. He may not be able to do it, but if he can he may say “my doctor is on tops of this. It’s normal and I’ll grow out of it.” By not giving his peers ammunition to make fun of him, they may just stop.

      I hope that helps.

    Thank you for all the information. I have 2 sons and one has already had a “mass” Gynecomastia, was what the Dr said was removed at the age of 20. It was first checked when he was 16, and we were told to wait. It was removed and no other problems were found. Now my 14 year old has developed one. Fingers crossed it is just the hormonal changes but it has increased in size in less than week. I think it best to have it checked now, any comments would be appreciated.

    Hi I’m like thirteen and I’m going to the seventh grade, I’m kind of worried And scared as well, well basically my left nipple is very big while the right one is normal! I’m 13 and 50 kg , I don’t really want to tell my family about this and I was kind of scared if it’s breast cancer or something,please reply I am very scared , well I don’t really do exercises and I eat junk food too , so should I change those? And should I tell me parents about this? Please please please reply , btw it doesn’t hurt unless I touch it , but it’s pretty obvious and my friends are starting to notice it.

    Added:
    • Lenni Doyel

      The fact that your friends are noticing means it’s probably time to tell your parents and go see a doc. If you have a physical before school starts, you could tell your doctor then, too. Or maybe make a special appointment. Not that it’s a big deal, but it’s good for you to have someone do a physical exam and tell you it’s okay.

      Having a better diet and exercising are always smart … no matter how old you are or what you’re dealing with.

    i have two lumps under both nipples, the left one used to be sore a while ago,but it shrieked in size and i does not hurt any more (it is still there). the other one came later, and it still is sore and when i squeeze it a white watery liquid comes out, even if just a little bit. i am currently 13 and the lumps are too small to be noticed trough a shirt of any kind, but because they are disk shaped they are pretty visible if i went swimming or something.

    IS THIS GOING TO GO AWAY? IS IT NORMAL AT ALL?

    Hello I’m 12 years old male, I have these kind of big lumps under my nipples and have been having the left nipple lump for about 3 months and the right nipple lump for about 3 weeks. I’m really scared because my left nipple gets puffy sometimes and flat sometimes but more puffy often and the right lump I’m really scared of more because I feel like there is a bug inside of my nipple.
    It hurts a little bit when I press on it but hurts a little bit more when I press it hard. I’ve had the left lump before about a year ago then came back 3 months ago. Plz tell me if I have breast cancer or if the lumps are harmful or harmless. Plz I don’t want to die:(. And also tell me if bugs can grow inside my nipple plzzz. Should I get it checked out?!?

    Doubt this is going to get a reply, but does anyone else have a lump that looks like another nipple? Sometime’s it’s tender but sometimes, it’s not. When you squeeze it you can feel this thin vein thingy or string underneath it. Is it a normal symptom of puberty or gynecomastia? Is it a breast bud?

    Hello, I am 16 years old and developed a lump underneath my left nipple around 1 – 2 weeks ago. I got it checked out and my docor thinks it’s a breast bud. It slightly hurts when I touch it, but other times it doesn’t. Another thing to note is that there is no discharge coming from the nipple, but my nipples are slightly red, in which my doctor told me that the redness can be from rubbing against my clothing. Should I be concerned about getting breast cancer? Or does this just sound like an actual breast bud?

      Thanks for writing in.

      As Dr. Greene says, “… at least 40% to 60% of boys” will experience breast lumps during puberty. These can be a normal part of puberty.

      I hope that helps.

    Added:
    • Hi, thanks for writing in!

      As Dr. Greene writes, times to worry about breast lumps are: “If they begin before age 10 years or after age 15 years (especially after puberty is complete),
      If they are not directly under the nipple,
      If there is overlying dimpling of the skin, skin ulceration, or change in the color of the skin,
      If the they feel fixed to the skin,
      If they are large–over 1.5 inches (4 cm) in diameter,
      If they don’t go away within 2 years,
      If the nipples leak milk, blood, pus, or other fluid,
      If there are other signs of disease–night sweats, fever, or weight loss, for example.
      These are all situations in which a breast lump should definitely be examined.”

      I hope that helps!

    Hi there, I turned 20 two months ago. Little over one year ago, I had a depression which affected me physically. I lost muscle, was sweating a lot during the day and night and two lumps formed under my nipples. My thought it that that was a hormonal imbalance. I excercised a lot and drank alot of water while avoiding alcohol and I started feeling motivated and happy again. I am now mentally and physically in top condition except one thing. Two tiny lumps under my nipples. It ruins the look of my chest (when I look in the mirror other people dont seem to notice) and reminds me everyday of the nasty period I had. How do I best combat it? My guess is that it needs to go quickly as I heard the longer its there the harder it is to get rid of it. It ruins a crucial part of my self image and really needs to go. Id love to hear from you.

If you are still going through puberty, consider this … Dr. Greene says, “… at least 40% to 60% of boys will experience breast lumps during puberty.” If you’ve completed puberty, in my opinion, it would be wise to discuss this with your doctor.

      Thanks for writing in.

      Dr. Greene says if a boy has a breast lump during puberty that lasts longer than two years “[the] breast lump should definitely be examined, in addition to the important regularly scheduled physicals during the puberty years. These children should have a careful physical examination right away. They should probably have an endocrinology (hormone) workup and perhaps an ultrasound or a mammogram, depending on the exam. I would also consult with a health care provider if a breast lump is associated with any signs of infection, such as sudden increased size, warmth, tenderness, drainage, redness, or fevers.”

      Sounds like it’s time for you to see your doctor.

    As Dr. Greene says, “… at least 40% to 60% of boys” will experience breast lumps during puberty. These are typically transitory and benign. At 13 and 1/2 you are likely in that category. If they don’t resolve and you are still concerned, it’s wise to discuss them with your physician.

      If the lump isn’t directly under the nipple, it’s worth having your son’s doctor take a look. It’s likely part of puberty, but worth having checked out just to be sure.

There is one under each nipper but they are pretty attached to my skin and won’t move around. They are also a little bit bigger than the size of a water bottle cap. They are also getting very thick and I am very paranoid because I am afraid of cancer. I can lift them up a bit but not much. I must also admit that I have hit puberty but I don’t have 2 testes like most boys due to a bicycle accident when I was younger, I have 1. It has gotten noticeably larger so I know I’m at that stage. Please help me and tell me what is going on. Is it lack of testosterone?

    Hello. I’m 16 years old, as of yesterday, January 7. I read that lumps can occur in boys with neurologic diseases. Well, I was wondering if it can occur in boys with multiple sclerosis? And how often? I’ve got a lump and I’ve also got multiple sclerosis. Should I do something about it? It’s very small, my family doesn’t have a history of gynecomastia, and last year in May, I was hospitalized and diagnosed with MS. And when I got discharged, the doctors put me on prednisone: 6 for three days, then 5 for three, then 4 for three, then 3, then, 2, then, 1. But the lump appeared before then, I’m not sure exactly when, though. But should I tell my doctor about it?

    Hello,

    My name is Kyle and I am twenty-five years young. I have a small, firm lump under my left nipple. It isn’t painful, and I’ve already gone to get an ultrasound test and they got the results right away and the doctor said that it was gynecomastia. The doc never even came into the room to examine it, she just passed word to the technician of the ultrasound. I’ve had this lump for about two and a half months. Should I get a second opinion? Also it feels like it’s apart of my muscle or my tissue. And if it’s cancerous I think I’m gonna sue that doctor because she didn’t even come in and exam me. And the technician said that they can know right away if the lump is cancerous. Please let me know. Thanks.

    Added:
    • Michael Obodai

      Hello Ashley 👋. What you are going through is just another phase of puberty all males go through. Its medically called gynecomastia. Its just as a result of your breast tissue enlarging and also excess estrogen. No need to worry. It would naturally go away in a year or two. But needs to be checked regularly by a doctor. Ask your doctor more about this. Never feel shy to speak to your doctor. Always be open to him yoyr health is your priority.
      And dont feel bad or ashamed about it. I went through it. I felt shy taking my shirt off. But dont! Its just another puberty “thing”. Thanks for allowing me to share my thoughts with you.

      Lumps under the nipple can be normal for boys going through puberty. If lumps are not under the nipple, start after the age of 15 or last longer than two years give your doctor a call and ask what he or she thinks.

          This is not normal. But no need to panic. Just go and see your doctor. This slightly drifts away from the normal puberty lumps called gynecomastia we all go through. See your doctor now. Dont feel shy always open up to him/her. Dont feel shy either about other people making fun out of with when you take of your shirt for sports or something else. Talk to your loved ones too about anything u feel is wrong with you.

    • Shawn,

      As Dr. Greene says, “… at least 40% to 60% of boys” will experience breast lumps during puberty. I’m guessing you’re in puberty and this is part of your changing hormones.

    Added:
    • Lindi,

      Dr. Greene says if breast lumps in boys begin after age 15 years (especially after puberty has ended) should be examined by a physician.

      I hope that’s helpful.

    Added:
    • Micho,

      Dr. Greene says above that you should worry about breast lumps if they start after age 15, after puberty is complete or if they last longer than two years. If any of those apply to you, it would be smart to see your doctor.

    My 16 1/2 year old son had noticed a very hard lump barely above his right nipple. Considering that on his father side, one aunt and two great aunts had been diagnosed with breast cancer, and his 22 year old brother had gynomastia surgery that found three lumps that were cancerous, I decided to make an appointment. He has been complaining of severe headaches and dizziness. I am not sure if it is related to seizure history. For their to be an issue, I was wondering if I would have to have the BRCA 1 and BRCA 2 mutation, or is it possible for that to skip me? My identical twin had lumps removed. I just do not have the disorder. His lump is hard and seems afixed to the skin.

    Added:
    • Shannon,

      I’m not an expert on this topic, so I can’t answer this question, but I know not all breast cancer is linking to BRACA 1 or BRACA 2 mutations.

      Does anyone reading this comment know about BRACA 1 and BRACA 2 mutation and skipping generations?

      So glad you’ve got a doctor’s appointment coming up.

    I am a 16 year old male with a hard lump directly underneath my left nipple, It hurts a little when I squeeze it and it moves a small bit too. Do you know what it might be?

    Added:
    • James,

      As Dr. Greene says above, “… at least 40% to 60% of boys” will experience breast lumps during puberty. These are benign, hormone induced lumps. At 16, you’ve likely started puberty, and not yet completely though puberty, so that would fit.

      You can check here for a list of the changes that occur during puberty.

    I have the lump on my right nipple and I can’t tell whether it is stuck to skin because every time I try to pull the skin away it kind of folds into itself like if you pinch your skin with a third finger in the middle but it does not detach from the under layer of either muscle or cartilage I don’t know what it is do you know if it can stay attached to the under layer and (maybe?) Skin

    I’m 14 years old and I have a small bump under my nipple, it’s about the size of a skittle and I think when I squeezed it a very very small amount almost unoticeable, sticky fluid came out. I’m very worried and I hope it’s not cancer, can someone help me??

    Added:
    • Sam,

      Let’s take a look at Dr. Greene’s list of when to worry about breast lumps in boys:

      • If they begin before age 10 years or after age 15 years (especially after puberty is complete)
      • If they are not directly under the nipple
      • If there is overlying dimpling of the skin, skin ulceration, or change in the color of the skin
      • If the they feel fixed to the skin
      • If they are large–over 1.5 inches (4 cm) in diameter
      • If they don’t go away within 2 years
      • If the nipples leak milk, blood, pus, or other fluid
      • If there are other signs of disease–night sweats, fever, or weight loss, for example

      It seems like you’re clear on everything, with the question of “if it leaks milk, blood, pus or other fluid”. I think, since you had to squeeze and then only a little came out, that it doesn’t fit Dr. Greene’s definition. But do keep an eye on it and if it starts to leak on it’s own or a lot comes out, it would be smart to discuss this with your doctor.

    Hi My Name is michael, Im 17 years old about to be 18 on january. I have my left nipple swollen and I feel like a little circle inside where it hurts a little when i touch it . It seems like its commected to the nipple because when it gets hard half of the nipples is more bigger and when i compare to my right nipple my right one ise flat. Is it normal? what do i need to do?

    Added:
    • Michael,

      Dr. Greene suggests that if you have a lump in your breast, even if it is under the nipple, it’s wise to have it checked out if you are the lump begins before age 10 years or after age 15 years (especially after puberty is complete). He also, suggests having it checked out by a doctor if you’ve had it longer than two years. So either it started after you were 15, or you’ve had it for longer than two years. Bottom line, it would be smart to have a doctor take a look.

    I am a 15 year old boy (16 in a month) and have a hard lump under my right nipple and a little bit to the right. It is very hard and doesn’t really move. (Keep in mind I still haven’t gotten through puberty (no penis growth or underarm hair yet, also still haven’t had my growth spurt). Just wondering if I should go to the doctor and get it checked out, because I am thinking of getting a physical soon, thanks!

    Added:
    • Michael,

      If you’re due for a physical (which is once a year at your age), bring this up with your doctor. Other than that, is is not on Dr. Greene’s list of “when to worry”.

  100. Worried MOM!

    My son went through a later puberty – it didn’t start until he was 15 or so.

    He’s 17 now. When he started puberty at 15, he got sore nipples (alternating, and the little lumps under each were different sizes and sore at different times.) That went away within a few months.

    He’s now 17 and one nipple is very tender again, and has a small sore disk under it. Is it uncommon to have this pubertal breast pain recur? He is definitely still growing. He is just starting to get the faintest of chin hair and his upper lip hair is getting thicker. Lots of back acne and his chest is getting wider. I took him to the pediatrician who gave him a thorough exam and palpation of the area. He says it’s pubertal. It’s been 6 weeks and the lump has enlarged some. Should I be worried?

      • At 13, lumps in your breasts can be completely normal, even after a year. But if you think you need to see a doctor, it’s wise to follow your instincts.

    Added:
    • Michael,

      Breast lumps (“lately it’s been swelling up”) in males who are through puberty should definitely be checked by a physician. It may be fine, but it’s much better to find that out sooner than to wait and be sorry.

    Added:
    • Tanner Anderson

      I am a 13 year-old boy, and I discovered a bump directly under the skin. It moves, and isn’t fixed to the skin. (I have bad anxiety and freak out at anything possibly bad) Do the math and you’ll feel better. You are probably going through puberty early and just have gynaecomastia like me. Tumors in the breast are ~0.8% men, only about 75% of tumors become cancerous, and cancer in children is so rare that you could fill a football stadium with children and about 1 or 2 would have cancer. This means that you have about a 0.001% chance of cancer. Nothing to worry about. (If you are still worrying, just get it checked out. Surgery isn’t that bad IF it is anything)

They hurt real bad when I bearly touch them. I am realy worried about breast cancer or a tumor!? They don’t seem to go away and I’ve had them since near the end of last summer. My friend and I both have it. But the relieving thing about us both, is that we’re the only boys in all of sixth grade to have hit a few signs of puberty.

    Hi my name is Kaylin and I am 14 turning 15. Two weeks ago I discovered that I have a lump under the side of my nipple and it pains when I uphold pressure on it. I don’t know what caused it. It doesn’t move much but isn’t fixed to the skin and it’s less than 1cm long. I haven’t experienced any of the cancer symptoms and I just noticed it a two weeks back. Should I be worried/consult a doctor?

    Dr Green,
    I am a 55 y/o man. When was about 14 y/o I had a hard and very painful lump that throbbed. I was embarrassed but the pain was so bad I told my parents. I went to an old time family doctor who gave me an injection and it (lump) went away in two weeks. Now, forty-one years later, I wondered what was in that injection. Did the doctor give me a shot of testosterone?

    Hi I am 14 and have a lump on my right under the nipple, sized around 4cm. I sqeezed it to see what would happen and it start leaking a unclear liquid like substance, is this normal or yeah? The symptems seem to be nirmal until I read the part of leakage. What should I do to?

    Added:

    Great thread, although I’ll still take my son to get checked by his Dr it is certainly nice to know chances are his nipple lumps are most likely very normal.

    I’m 14 and iv’e had a bump ‘above’ my nipple and when I looked through the comments and realised no one else has had it above their nipple but only below, this is quite concerning as I don’t know what it is. It doesn’t hurt but I did start picking it around a month ago and each time it starts to heal I pick it again, so it does sting a little, so if you have any information please contact my email thanks.

    Hi i’m 17 turning 18 in a couple months, i’ve read into this a couple of years ago. I have a lump under my nipple since I was 14ish and I still have it. (3 years later). It does not hurt anymore. Should I get this checked out?

    Added:
    • Hi Danny,

      Since you’ve had it so long, and you’re getting older, it’s probably wise to have it checked. Likely you’re due for a complete physical exam and potentially immunization(s). You can easily bring this up at that visit.

    Hi Dr Greene,
    Thank you for writing about this. My son is 4 years old and has a fairly hard lump one inch directly below his left nipple. The skin over it looks normal and there is no redness. The lump is approximately 1/2 inch across and raised about the same height. It is able to move under the skin about half an inch in any direction. He is nonverbal and doesn’t respond to pain signals so I can’t tell if it’s tender or sore to him.
    If you can give me some insight I would really appreciate it.
    Thank you so much for your time.

    Okay so I’m 14 years old soon to be 15 and these bumps on both of my nipples are getting bigger there is 3 on the left and 6 on the right they are huge and even when I lay down on my stomach it brings pain my parents said its supposed to happen but I’m not so sure about that and I know when there is something wrong with my body. Please give me any type of information

    Added:
    • Jeffrey,

      I applaud your sense of self — “I know when there is something wrong with my body”. Don’t let go of that. Even if it’s “normal” you should follow your instincts and have it examined by a pediatrician or family practice doctor. He should be able to tell you if this is normal or not and what to expect for the future.

      Hope that helps,

    Such a helpful article! Thank you. My 13 year old son is always asking me about changes in his body. I was stumped and scared when he asked me why his nipples were sore. I went to look and noticed this hard lump under both of them. I tried asking my friends but they were equally as uncertain… This article not only cleared up that mystery but also shed so much insight into this stage in my sons life and what he may experience. I’m sure there will be many questions. I feel a little more prepared to answer them now.

    Hi, I’m 13(and a half) years old and about 3 months ago I noticed a bump on my left nipple. Over the past few weeks a bump has been starting to grow on my right nipple. The bump on my right nipple is a little bit smaller than the one on my left. It hurts if I press on it( for example leaning on my arm on a table or a flat surface). I am a little worried because I have never witnessed or seen anything like it on my body. I know it is a time of change for my body at the ages of 13 but I would like to know if it could effect the function of some parts of my body or if it is just a normal thing.

    Hi, I’m 15 years old. I don’t remember if my nipple enlargement started after the age of 15 or not, although I doubt it did. But, I do fear one thing: this might sound weird, but does “change in the color of the skin” mean an abnormal color or the normal way your nipple should be darker than the rest of your skin? Also, I am worried about that fact that I have experienced night sweats a couple of times, not everyday or anything. Should I be worried?

      Like Dr.Greene said look at the things he wrote that you should be worried about, and it said if its not directly under the nipple, and if the child is under 10 you should worry about it. So it is probably best to get it checked out if you haven’t already

    Added:
    • It’s understandable to be nervous whenever you find a lump. Breast lumps stir up all the images of pink ribbons and breast cancer awareness. In boys who are entering of going through puberty, these lumps are typically transient and not harmful. None-the-less, it’s wise to tell your mom or dad and to be checked by a pediatrician. The only likely outcome is that you’ll feel better, but wouldn’t it be nice to stop worrying about it?

    My son recently told me about a lump on his left chest. He is 9 and will be 10 soon. After about a week of him being in discomfort and the lump still being present, we set him up with a Dr. appointment. The Dr. mentioned similar things regarding what your article said, however I am still concerned because my son is so young. Also, the lump is slightly above his nipple opposed to below and its extremely tender to touch. At the moment, the Dr. prescribed him to take Motrin for the pain as well as applying ice pack or heat pack, which ever helps. I guess the biggest question I have is if I should ask the Dr. to run more tests or if this is what it could be. I am just still worried and not sure what else I should ask.

    Added:
    • Hi Melisa,

      I’m not a doctor, but I’m a mom.

      Puberty is starting sooner and ever and even though 9 is young, this may be an early sign that his hormones are changing. Is he showing any other signs of puberty?

    I am 15, pretty late to puberty, I had my first ejaculation a few months ago. I got my first lump on my left nipple when I was 12, it dissapeared after a few months, then I got another one on the opposite nipple. A month ago that one dissapeared. And I just noticed one on my left nipple again.
    They are half a centimetre in size, are hard and sensitive to the touch.

    Do you have any idea what this is, or if it is normal? My parents know about it but don’t think to much of it. But I can’t be sure.

    Thanks a lot

      These changes happen fast. What your going through is normal and your still very young. The development of pubic hair is a big change and you will get use to the smell. Wait a while and if your still worried, tell someone and go to the doctors ☺

I have told my parents and they are watching it and making me keep them updated on any drastic changes in the lump.Can I get some more detail on what exactly happens in SMR3 and SMR4 so I can be more aware of the things that will or may be taking place in my body right now and the upcoming years.Please and Thank You.

    I have a lump under my left nipple. I’m scared. I’m 11 going on 12 soon. What do I do? I can’t tell my parents. Please help and I’m scared I have cancer.

    Added:
    • At your age, you really do need to tell your parents. IF that is out of the question, you need to tell a trusted adult such as your pediatrician or the school nurse. It’s likely not cancer. It’s likely hormones from going into puberty, but you need to talk to an adult who can help monitor your health.

    Tonight before bed my 12-year-old son said, “mom I have a lump under here” and it was his left nipple. I got so scared. I was terrified. My husband started joking around and he thinks he has one, too. He has my body fat, so I’m concerned that he could end up with male breast cancer and I wasn’t in the mood for joking around. I immediately went outside so I wouldn’t get in a fight with my husband and went on the Internet to find out more. Your information really put me at ease. Ironically we have a wellness check up tomorrow so I can bring it up to his doctor, but I’m pretty sure it’s hormonal because all of a sudden his body odor seemed very strong just this past week which I hadn’t noticed before. He is definitely growing, eating way more, feet growing a ton, so this article and the answers to the questions you gave put me at ease. Thank you Dr. Greene, now I can sleep.

      You definitely need to tell your parents. That sounds serious and I’m sure your parents are more concerned for your health and wellbeing than anything else.

    • roadster1252

      I’m not a doctor, I’m a mom :) I think that you should let your parents know. Perhaps it is nothing and your parents can reassure you, or perhaps it is something that your parents can take you to a doctor for to check out and make sure things are okay. Either way, please don’t suffer in fear, tell your parents, you are worth it! If you are not able to talk to your parents about it, let a close relative or other trusted adult know about it. The important thing is to make sure you are healthy! Good luck!

    I don’t know if I should be worried about my gynecomastia. I am currently 17 and am going into my senior year. I hit puberty early, circum age 10-11, and noticed one lump under my left nipple in January of 8th grade. I was worried at the time, and my physician told me it was normal. A second lump appeared but under my right nipple a few months later. Now it has been 3 1/2 years since the first lump. I cannot determine the size of each since they are under tissue. They have not leaked, remain around the same size, have not caused discoloration, and have not caused night sweats. I have experienced weight loss, however. Since 8th grade, I have grown 6″-7″ and have lost 15-25 lbs since 9th grade.
    I assume they will begin to go away closer to the end of puberty.

    Added:
    • Unintentional weight loss should always be looked into to be sure everything is okay.

      Kyle,
      I am also going into my senior year and have had lumps under both of my nipples since the end of 8th grade. I assume it is a normal part of the puberty process, but I hope they go away sooner rather than later because they are really embarassing.

I am 15 years old, I got this lumps around 11 or 12 year old maybe and it hasn’t been gone ever since. It does not leak anything and I didn’t feel anything different with these two lumps.

    Hi doc, I’m 15 years old and I’ve only just noticed the lump under my right nipple yesterday. I will be honest, I haven’t started puberty yet and I’m starting to get very concerned. I have always been small and under developed and this lump hasn’t helped! What should I do?

    Added:
    • Hey Claran,

      As the article states it’s probably not an issue, but since you’re 15 and haven’t started puberty, this would be a good time to get a check-up from your pediatrician or family doc. Be sure to let him know your concerns, even if you feel embarrassed talking about it.

    Dr. Greene,
    My 6year old son developed a hard lump under his L nipple right around the time he was diagnosed with strep throat. He complains it hurts and is now on a second dose of antibiotics. Drs don’t seem concerned I however am. I’m an RN and wonder if it could be lymph. Your thoughts would be appreciated.

  230. Zach

    Dear Dr. Greene,

    I am 16 years old, and have had what I would estimate to be 1.25 cm lumps under both nipples for at least 2.5 years, very probably more. I achieved puberty quite late, as did my dad, so that seems regular. However, there is no history of breast cancer, nor Klinefelter syndrome in my family. These lumps look like they aren’t going away, and I’d like to know first, whether I should be worried in these circumstances, and second, how I can fix it, as I am, admittedly, fairly embarrassed about the condition. I read the article, and I don’t show any of the more severe sounding symptoms; no pain to the touch, no liquid, just the lumps, but they’ve been there for a long time. I would bet much appreciate your counsel.

    Sincerely,
    Zach

    Hi Dr. Greene,
    My 14yr old son has been complaining for over a week about his nipples hurting. He finally let me check and there are lumps under both nipples. They are soft but firm, but not pea size, more around size of dime. I’ve read a few books and websites that state that this just hormones. But I have a history of breast cancer and thyroid cancer in my family. His father wants to wait a week to see if it goes away, but I think we need to see a doctor now.

    I’m 17 yrs old and 3-4 months back I observed a small lump right under my right nipple which is still growing I think as it is 2 cm wide diametrically and is a bit painful to touch. At first I thought it to be same type of growth as I have in my hands, small lumps my mom also has some and her sister has loads of them so I thought it would go away. Now, as of March, under my left nipple a small lump has started to grow. Could you suggest what do I do?

    P.S. My mom takes estrogen pills due hormonal imbalance and she attained her puberty very late. I too think am attaining late as I just have small hairs over my lips it is growing — added for your better grip of my case :)

I am concerned about the possibilty of cancer. But I don’t know if I should ignore it or take him to the doctor. I am concerned because of his age.

    I worry that if I ignore it and it is something it may get worse and become serious. But then I also don’t want to over react and be all paranoid.
    Should I take him in or do the wait and see what happens thing?

    Out of all the articles I read on the internet yours was the most informative. Thank you. But I have one question about lumps in the areola area of the breast in pediatric boys. In the later part of your article you mention when its not hormonal it could be something more serious. No mention of tenderness in the lumps.

    Would you say if its tender its less serious?

    My son is 18 and about 10 days ago we took him to the er for a hard lump under his left nipple. They said “it was most likely from puberty and that it should go away on it’s own. But that if it didn’t or got larger he should get it checked out.” Well he just showed me again that it’s gotten significantly larger. You can notice it through his clothing. The difference is is that it’s not as hard. There’s still a hard knot. But it’s also mushy. I have a family history of breast cancer on both sides of my parents families. Should I be the overly concerned parent or is it still part of puberty?

    My comment is similar to most of the posts. My son turned 11 today and discovered a lump on left breast right before our vacation last week. He said it doesn’t really bother him, but knowing it is there, he is fixated on it. In addition, he has been on Risperdal since he was 4 and I’m seeing a surge of information these days regarding breast growth associated with Risperdal. We have a slew of labs ordered and will be getting them in the morning. I am having a difficult time finding first hand information regarding medication and it’s effects on the endocrine system. How often do you see scenarios such as this? Thanks!

    Hi Dr. Greene,
    my son is 3 1/2 and he has had a tiny cyst like node on his right nipple, on his arreola. It seems like these breast lumps are a somewhat normal thing for girls/boys in the puberty stage, but is it normal for a toddler? I think he’s had it since he was before 2 years old, but and i never thought anything about it until now. He often plays with it and I am just curious about it now. It feels hard and it is underneath the skin. It is beside his nipple. Thank you..

      Mark, the good news is that most of the time this turns out to be fine in babies – and especially when it’s been seen by a pediatrician who is not concerned. I do suggest, though, having it checked at every doctor’s visit to be sure the progress is matching expectations. All the best!

    My concern with this is that there may be too much estrogen their bodies!! And he’s getting an overload somewhere! I have an 11 yr old who just had a bud, and i’m not sitting around and waiting for it to go away! I have ALWAYS fed my children organic, have a water purifier on the house, they drink 100 % natural spring water that is delivered in a GLASS container; my household cleaners are all natural, soap derived (not oils, such as tea tree, rosemary, sesame, lavender.. these all MIMIC estrogen!!! ), so for me, I don’t know where he is getting the extra estrogen from. I am giving him a supplement of DIM twice a day… it’s for women who are estrogen dominant. It’s naturally derived from broccoli. Hope this helps some people who may ‘blow this off’

    • I agree, Debbie, that reducing excess estrogen exposure is wise for all of us. The hormones used to fatten conventional cattle are still there when you by beef at the supermarket — Beef is one of my top foods for people in general to choose organic over conventional (http://www.drgreene.com/dr-greenes-organic-rx-item-8/), and at the top of my list for pregnant women and kids (I’m not saying they should eat beef, but I recommend that if they do, they choose grass-fed organic). The pesticide atrazine is another big concern for me. It works by by turning testosterone to estrogen. It’s the number two herbicide in the US, and in the drinking water of 30 million Americans. But if you are drinking purified water and eating organic food, the risk of exposure is far lower – unless you live in the corn belt. I’m glad you mentioned GLASS, because as you know, many plastics contain estrogen-like compounds.

      Vitamin D, Brazil notes, and almonds may help improve the estrogen ratio.

      But having said all this, the lumps in healthy, normal-weight boys going through puberty are thought to be a normal part of their own pubertal hormone surges and not a reason for concern themselves.
