Skin cancer – melanoma
Definition of Melanoma
Melanoma is the most dangerous type of skin cancer. It is the leading cause of death from skin disease.
Causes, incidence, and risk factors
Melanoma can appear on normal skin, or it may begin as a mole or other area that has changed in appearance. Some moles that are present at birth may develop into melanomas.
The primary symptom of any skin cancer is usually a mole, sore, lump, or growth on the skin. Any change in appearance of a pigmented skin sore over time is a warning sign. Also, watch for any bleeding from a skin growth.
Signs and tests
If you notice any suspicious skin markings, see your health care provider as soon as possible.
The cancerous skin cells and some normal tissue that surrounds the cancer will need to be surgically removed. How much normal tissue is removed depends mostly on how deep the melanoma has grown.
Treatment success depends on many factors, including the patient’s general health and whether the cancer has spread to the lymph nodes or other organs.
