The cervix is the lower portion of the uterus (womb) that is located at the top of the vagina. Cervical cryosurgery is the use of extreme cold to freeze areas of the cervix.
This procedure is done to destroy and remove abnormal cells of the cervix, particularly precancerous cells.

Complications are rare. However, no procedure is completely free of risk. If you are planning to have this procedure, your doctor will review a list of possible complications. These may include:
Factors that may put you at risk for complications during this procedure include:
You may want to plan for someone to drive you home.
Normally, no medications are needed for this procedure. However, pain medications such as ibuprofen, naproxen, or acetaminophen are usually taken. They should be taken about an hour before your appointment. Ask your doctor if this is recommended for you.
A device called a speculum is inserted into the vagina to hold it open. The cryosurgery probe is inserted into the vagina. Nitrous oxide makes the tip extremely cold. The tip is touched to abnormal areas on the cervix. It is held there for a few minutes. The tip is removed. This allows the tissue to return to its normal temperature over the course of 3-5 minutes. This freezing and thawing cycle may be repeated several times for each abnormal area on the cervix.
You will remain lying down for at least ten minutes after the procedure. Some women may feel lightheaded and/or flushed after the procedure.
You will probably feel some cramping during the procedure. Some women also describe a burning sensation.
When you return home after the procedure, do the following to help ensure a smooth recovery:
The abnormal tissue of the cervix should shed and flow out of the body in a watery vaginal discharge over 4-6 weeks. In some cases, more than one cryosurgery session may be scheduled.
After arriving home, contact your doctor if any of the following occurs:
If you think you have an emergency, call for emergency medical services right away.
