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 also be dark, flat and smooth. The appearance of a wart depends on where it is growing. The different kinds of warts include common warts, which usually grow on the fingers, around the nails and on the backs of hands; foot warts (or Plantar warts); and flat warts.

Warts can be treated by applying salicylic acid gel, solution or plaster. For adults and older children, cryotherapy (freezing) is generally preferred. Electrosurgery (burning) is another good alternative treatment, while laser treatment can also be used for resistant warts that have not responded to other therapies.
