Warts are benign (not cancerous) skin growths that appear when a virus infects the top layer of the skin. Viruses that cause warts are called human papillomavirus (HPV). Warts appear most frequently on the hands and feet but can occur anywhere on the body. You are more likely to get one of these viruses if you cut or damage your skin in some way.
Wart viruses are contagious. Warts can spread from person to person and from one part of the body to another.
Warts are often skin-colored and feel rough, but they can be dark (brown or gray-black), flat, and smooth.
Warts can be treated with destructive modalities or with immunotherapy.
