Cryotherapy
Cryotherapy is an inexpensive, safe and easy procedure to remove skin lesions and spots. Cryotherapy is commonly performed with liquid nitrogen. Carbon dioxide snow may also be used, but liquid nitrogen at the temperature of -196 degrees centigrade is preferred.
Warts, lentigens and actinic keratoses are removed with liquid nitrogen. Other skin lesions can also be removed with liquid nitrogen. In cryotherapy, liquid nitrogen is applied on the lesion to be removed. The liquid is applied for few seconds on the spot and it burns away the lesion. Some swelling or blister may form, which is treated with antibiotics or steroids. Within a few days the skin heals, normally showing no signs of the earlier lesion. Sometimes, the skin looks lighter than the surrounding skin. Your doctor will discuss all the issues of cryotherapy with you before performing it.
