The Goods on Cryotherapy
Cryotherapy is a treatment in which skin lesions are frozen. It is most commonly used on warts and solar kerotoses, although it is rarely used to move cancerous growths. Typically, your doctor will use liquid nitrogen, either by dipping a swab in it or with a probe that has it flowing through it, to treat the specified area.
After cryotherapy, the treated skin will turn red, and within hours, blisters may form. Scarring can occur, especially, if the treated area was deeper in the skin or if the procedure was prolonged. The skin in the treated area may also turn white.
For most patients, cryotherapy works in very well. Some skin lesions, especially warts may require additional treatments.
