Warts are benign (benign) fleshy growths on the skin caused by the human papillomavirus ( HPV) . They can appear anywhere on the body and are most common in children and young adults. Most warts, with the exception of some that form on the soles of the feet, are painless.
However, all warts are very contagious. They can be easily transmitted from one part of the body to another and from one person to another, even through casual contact, such as a handshake. They often go away on their own, but can be treated with topical medications or removed with non-invasive procedures.
Warts are easy to spot just by looking at them. Although they are benign, in very rare cases, warts are known to develop into a very slow-growing cancer called warty carcinoma. If you have a wart that bothers you or does not go away, ask your doctor to examine it.
