Cryosurgery is a process which involves “freezing” of warts, benign growths and other such lesions with the help of liquid nitrogen.
After application of the gas typically a blister forms after a few days and the lesion falls of subsequently.
Cryotherapy is also used for keloids in combination with other treatments to give optimal outcomes.
