This type of surgery destroys cancer cells by freezing them. The surgeon takes care to try to keep healthy cells and tissue from being frozen along with the cancer cells.
Cryosurgery may be advised for many types of cancer, including:
- Skin cancer.
- Liver cancer.
- Cervical cancer or precancer.
- Prostate cancer that is only in the prostate.
- Bone cancer.
- Retinoblastoma, a cancer of the eye that occurs in childhood.
- Lung cancer.
Several different procedures can be used to freeze cancer cells. For instance, to treat skin cancer, cells are often frozen using liquid nitrogen or argon gas. This may be sprayed or applied right on the skin. To treat tumors in the body, a thin tube is put into the tumor. The tip of the tube puts intense cold on the tumor. This destroys the cancer. During this procedure you are given medicine (anesthesia) that puts you into a deep sleep.
Risks and side effects include some bleeding and scabbing at the site of the cryosurgery. Depending on where the tumor is, you may have other side effects. These include hair loss if it's outside the body, spotting for treatment of a cervical cancer, or coughing up blood if it's treatment for lung tumors.
