Why have cryotherapy

Your doctor sprays liquid nitrogen on to the area of cancer. Or they put it directly on to the area with a cotton swab. The liquid freezes the area. After treatment the liquid nitrogen dissolves and the area thaws. A scab forms in the area. Over the next month or so the scab falls off along with any dead cancer cells. Rare and longer term side effects might include scarring, numbness in the are and changes in skin colour, it may become either lighter or darker.

For cancers inside the body, a small probe is inserted next to or inside the tumour. This probe is called a cryoprobe. The cryoprobe is attached to a supply of liquid nitrogen controlled by the doctor. Your doctor or specialist nurse will talk to you beforehand about how you will have treatment and exactly what is involved. Some cancers need to be frozen and thawed a number of times. Depending on the treatment area, it can take from a few minutes to a couple of hours. To help the doctor position the cryoprobe you may have either an ultrasound scan or CT scan.

The position of the cancer in the body affects how the doctor puts the cryoprobe into the area. You might have a general or a local anaesthetic, if you are having the cryoprobe put in through our skin. For example, men having cryotherapy for prostate cancer have the probes put into the skin of the perineum the area of skin between your back passage and your testicles.

And for cryotherapy to the liver the doctor puts the probe in through the skin of the abdomen. For kidney cancer a thin, flexible tube called a laparoscope is used to help position the cryoprobe. The laparoscope has a light and a tiny camera at the tip. A small cut is made in the skin on the side of the abdomen to put the laparoscope through. The other way to reach tumours inside the body is by using a scope without going through the skin. They show that cryotherapy destroys all of the abnormal tissue in 77 to 96 out of cases.

Destruction of the abnormal tissue will not be complete if the abnormal cells are too deep in the cervical tissue. Kiley MD - Obstetrics and Gynecology. Author: Healthwise Staff.
