Procedure Description:

Freezing treatment of the cervix

What To Expect:

This is a cervical freezing procedure designed to eliminate the abnormal cells to a depth of 1/4 inch. A metal tip attached to a nitrous oxide gas is applied to the cervix for a 3 minute freeze, followed by a 10 minute rest, then a second 3 minute freeze. The frozen cells will die and slough off over the next 3-4 weeks. You will feel some cramping during the procedure, but nothing will feel cold.


Nothing in the vagina for 24 hours prior to the procedure, including sexual activity, douching, tampons, or vaginal medications. Take 600 milligrams of ibuprofen or 2 Aleve tablets 30 minutes before the procedure.


The cramping usually subsides quickly. You may use Aleve or ibuprofen for more persistent cramping. You will experience a vaginal discharge that may be bloody, green/yellow for up to 3-4 weeks, as the frozen cells are sloughed off. Nothing in the vagina at all during this time of discharge, including sex, tampons, douching. No "community water" such as pools, hot tubs, lakes/rivers/oceans until the discharge is done. You may sit in your own bathtub at home. You will be given a prescription for a soothing vaginal cream that you will use nightly for 7 nights after the procedure.
