Cryoablation is a treatment to kill cancer cells with extreme cold. Cryoablation may be used to treat cancer when surgery isn't an option. Cryoablation is sometimes used as a primary treatment for cancer of the kidney, liver, lung and prostate. Cryoablation is also used to relieve the pain of many different types of cancer that spread to the bone (bone metastasis) or other organs.

Cryoablation may also be called percutaneous ablation, cryosurgery or cryotherapy.

During cryoablation, a thin, wand-like device (cryoprobe) is inserted through your skin to the cancer. A gas is used to freeze the tissue. Then the tissue is allowed to thaw. The process may be repeated during the same treatment session.
