What to Expect
Prior to Procedure
The care team may meet with you to talk about:
- Taking pain medicine before the procedure
- Any allergies you may have
- Current medicines, herbs, and supplements that you take and whether you need to stop taking them before the procedure
- Whether you need a ride to and from the procedure
Description of Procedure
A tool called a speculum is inserted into the vagina to hold it open. A probe is inserted into the vagina. The cold tip of the probe is touched to abnormal areas on the cervix and held there for a few minutes. The tip is removed. This allows the tissue to return to its normal temperature over the next 3 to 5 minutes. This freezing and thawing cycle may be repeated for each abnormal area on the cervix. The probe and speculum will be removed.
How Long Will It Take?
10 to 20 minutes
Will It Hurt?
Cramping and burning are common after the procedure. There may also be lightheadedness and a flushed feeling. Medicine and home care help.
At the Care Center
After the procedure, the staff will have you lie down for at least 10 minutes.
The abnormal tissue will shed and flow out of the body in a watery discharge. This will take 4 to 6 weeks. Tampons and sex will need to be avoided during this time.

- Signs of infection, such as fever and chills
- Pain that you cannot control with medicine
