Cryosurgery is a method of superfreezing tissue in order to destroy it. The technique is used to treat tumors, control pain, and control bleeding.

Cryotherapy

The cold is introduced through a probe which has liquid nitrogen circulating through it. To destroy diseased tissue, the tissue is cooled to below -20 degrees Celsius. Other procedures that control pain or bleeding are cooled to a lesser degree to prevent tissue damage.
