This is often not what someone would think of when one thinks of surgery, but that is how it’s classified medically! Cryosurgey is used to destroy a growth by freezing the abnormal tissue.
With cryosurgery, liquid nitrogen is applied to the lesion via a cry-ac, cotton swab, or other device to kill the growth. This is commonly performed on actinic keratosis, seborrheic keratosis, and warts.
