Warts are non-cancerous skin growths, caused by a virus, that occur in the top layer of the skin. They occur in people of all ages and transmission is usually by direct contact. Typically they are a flesh-colored, raised, calloused growth seen on the hands and feet; however, they can occur anywhere on the body. Treatment options include salicylic acid preparations, prescription creams, in-office topical solutions and cryotherapy or laser surgery.
