Cryosurgery is a technique for removing skin lesions that primarily involve the surface of the skin, such as warts, seborrheic keratosis (noncancerous skin growth), or actinic keratosis (A rough, scaly patch on the skin caused by years of sun exposure.).
Liquid nitrogen needs to be applied long enough to freeze the affected skin. By freezing the skin, a blister is created underneath the lesion.
Ideally, as the new skin forms underneath the blister, the abnormal skin on the roof of the blister peels off. Occasionally, if the lesion is very thick (such as a large wart), only the surface is blistered off. The base or residual lesion may need to be frozen at another visit.
Talk to your physician about it. To schedule an evaluation with a Memorial Hospital Provider contact one of our Rural Health Clinic Locations.
