Definition of Warts
Warts are small, usually painless growths on the skin caused by a virus called human papillomavirus (HPV). They are generally harmless. However, warts can be disfiguring and embarrassing, and occasionally they itch or hurt (particularly on the feet).
Causes, incidence, and risk factors
The typical wart is a raised round or oval growth on the skin with a rough surface. Compared with the surrounding normal skin, warts may appear light, dark, or black (rare). Most adults are familiar with the look of a typical wart and have little trouble recognizing it. Unusual warts with smooth surfaces or flat warts in children may be more difficult for parents to recognize.
Signs and tests
Warts can generally be diagnosed simply by their location and appearance. Your doctor may want to cut into a wart (called a biopsy) to confirm that it is not a corn, callus, skin cancer, or other similar-appearing growth.
Over-the-counter medications can remove warts. These are applied to the wart every day for several weeks. Do NOT use these medications on your face or genitals. It helps to file the wart down when damp (for example, after a bath or shower) before applying these medications. Do NOT treat warts on your face or genitals yourself. See your health care provider.
Warts are generally harmless growths that often go away on their own within 2 years. They can be contagious, but transmission from person to person is uncommon. Warts may be unsightly or cause discomfort, especially on the feet.
