What is cryosurgery?
Cryosurgery is a method of killing tumor cells with extreme cold temperatures using liquid nitrogen. The tumors best treated with cryosurgery are small, benign masses less than one inch in diameter. Typically, these masses are located on the eyelid, anus, mouth, or skin. Depending on the location of the tumor, the patient may require sedation, local anesthesia, or general anesthesia to perform cryosurgery.
