Cryosurgery, also known as cryotherapy, is a minimally invasive treatment that uses freezing cold temperatures to destroy abnormal tissue cells. These cells can include skin tumors, nodules, skin tags or other unwanted lesions on the skin that may be of medical or cosmetic concern.
During the cryosurgery procedure, your doctor will apply nitrogen directly to the skin. The diseased cells cannot survive extremely cold conditions and will be destroyed. Cryosurgery has a shorter treatment and recovery time than surgical procedures while providing highly effective results. Pigment loss and swelling may occur in the treated area after this type of surgery, but most patients are able to achieve successful results with cryotherapy.
