"Warts are typically small, rough, hard growths that are similar in color to the rest of the skin. They typically do not result in other symptoms, except when on the bottom of the feet, where they may be painful. While they usually occur on the hands and feet, they can also affect other locations. One or many warts may appear. They are not cancerous.
Warts are caused by infection with a type of human papillomavirus (HPV). Factors that increase the risk include use of public showers, working with meat, eczema and a weak immune system. The virus is believed to enter the body through skin that has been damaged slightly. A number of types exist, including "common warts", plantar warts, "filiform warts", and genital warts. Genital warts are often sexually transmitted." - (en.wikipedia.org 18.12.2019)
