Cryosurgery

Cryotherapy is often used for precancerous conditions like actinic keratosis or small basal cell and squamous cell carcinomas, as well as warts.

Sometimes called cryotherapy, it is not a surgical procedure that involves cutting of the skin. Rather, it is the use of extreme cold produced by liquid nitrogen to freeze and destroy abnormal tissue. The liquid nitrogen can be applied directly to the skin with a spraying device or a cotton swab.

This process is repeated several times in the same clinic visit. After the affected area of skin thaws, it will swell, blister and crust. The wound may have fluid draining from it for a period of time and take a month or two to heal, leaving behind a scar and possible discoloration after treatment. Mild blistering and tenderness are also expected results and part of the normal process for destruction of abnormal tissue.
