What to Expect
Prior to Procedure
The care team may meet with you to talk about:
- Timing the biopsy with your menstrual cycle
- Anesthesia options
- Any allergies you may have
- Taking pain medicine before the biopsy
- Current medicines, herbs, and supplements that you take and whether you need to stop taking them before the biopsy
- Whether you need a ride to and from the biopsy
The doctor may give local anesthesia. The cervix will be numbed.
Description of the Procedure
A speculum will be inserted into the vagina. An tool called a tenaculum will be inserted and used to grasp the cervix. A flexible, thin, suction tube will be passed through the vagina and into the uterus. A small sample of endometrial tissue will be suctioned out. The tools will be removed.
How Long Will It Take?
About 10 to 15 minutes
Will It Hurt?
Pain is common after the procedure. Some women may also feel lightheaded or flushed. 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 cramping and bleeding will go away in a few days. Tampons and sex will need to be avoided.
The doctor will get the results from the biopsy in about a week. A treatment plan will be made.
