Warts are non-cancerous skin growths caused by a viral infection in the top layer of the skin. Viruses that cause warts belong to a "family" called human papillomavirus. The appearance of a wart depends on where it is growing. Warts are usually skin-colored and feel rough to the touch, but they can be dark, flat and smooth.
Dr. Miller uses a variety of treatments for warts depending on the age of the patient and the type of wart. For adults and older children, cryotherapy (freezing) is generally preferred. This treatment is not too painful and rarely results in scarring. However, repeat treatments at one- to three-week intervals are often necessary. Electrosurgery (burning) is another good alternative treatment, removing the wart in a single office visit. Scarring and pain are more likely to occur with electrosurgery than with cryosurgery.
