What are warts?
These skin growths are caused by the human papillomavirus (HPV). There are more than 60 kinds of HPV, some of which tend to cause warts on the skin. The virus stimulates quick growth of cells on your skin's outer layer. In most cases, common warts appear on your fingers, near the fingernails, or on your hands. Certain types of HPV can also cause warts on your private parts.
