Cryosurgery for Nonmelanoma Skin Cancer
Cryosurgery is the process of destroying a skin cancer (lesion) by freezing it with liquid nitrogen. Liquid nitrogen is applied to the lesion using a cotton applicator stick or an aerosol spray.
The skin may first be numbed with a local anesthetic. The liquid nitrogen is applied or sprayed onto the cancer and the immediate surrounding tissue. The application may be repeated. An antibiotic dressing may be applied to the wound.
Cryosurgery is often used to destroy precancerous skin lesions such as actinic keratoses but is rarely used alone (monotherapy) to treat skin cancer.
