About Wart Removal

Warts are outgrowth lesions on skin. Most of the types of warts are contagious. They spread from person to person by direct contact through the skin. Kids and immunocompromised patients are mostly at risk.

How to treat Warts:

  • Cantharidin: We may treat a wart by “painting” it with cantharidin. Cantharidin causes a blister to form under the wart.
  • Cryosurgery: For common warts in adults and older children, cryosurgery (freezing) is the most common treatment.
  • Electrosurgery and curettage: Electrosurgery (burning) is a good treatment for common warts, filiform warts, and foot warts. Curettage involves scraping off (curetting) the wart with a sharp knife or small, spoon-shaped tool. These two procedures often are used together.
  • Laser treatment: Laser treatment is an option, mainly for warts that have not responded to other therapies.
