Warts

Warts are non-cancerous skin growths caused by a viral infection in the top layer of the skin. Viruses that cause warts are called human papillomavirus (HPV). Warts are usually skin-colored and feel rough to the touch, but they can be dark, flat and smooth. The appearance of a wart depends on where it is growing.

There are several different kinds of warts including:

  • Common warts
  • Foot (Plantar) warts
  • Flat warts
