In some cases, once the probe is inserted, a number of electrodes will be placed into the area. This will let the doctor treat a larger area of tissue.
A small amount of heat will be introduced through the probe. The heat will destroy the abnormal tissue. The probe may be repositioned to destroy other areas of tissue.
You will be monitored for 2-3 hours after the procedure.
