What is an endometrial biopsy?
An endometrial biopsy is a simple procedure done to learn
more about your condition by taking a sample of the lining
of your uterus. The uterus is the organ at the top of the
vagina. Babies develop in the uterus, and menstrual blood
comes from the uterus. The lining of the uterus is called
the endometrium.
When is it used?
Examples of reasons of reasons for doing this procedure are:
- The uterus is bleeding too much, at the wrong times, or
not at all.
- You are having bleeding after menopause.
- You are having trouble getting pregnant.
- Your provider wants to check on the outcome of treatments
you have had.
Examples of alternatives to this procedure are:
- D&C (dilation and curettage, which means stretching the
cervix and scraping the inside of the uterus for a
tissue sample)
- hysteroscopy (exam of the uterus using a thin
telescopelike tube with a camera and a tool to remove
part of the endometrium).
Another alternative is to choose not to have any procedure,
recognizing the possible risks of your condition. You
should ask your health care provider about these choices.
How do I prepare for an endometrial biopsy?
Follow instructions provided by your health care provider.
Your provider may prescribe a mild pain pill to take an hour
before doing the biopsy.
What happens during the procedure?
You do not need an anesthetic for this test. The procedure
can be done in your health care provider's office.
Your provider will clean the cervix with antiseptic. Then
he or she will gently stretch open your cervix. Your
provider will insert a tiny strawlike tube into your vagina
and then into the uterus through the cervix. The tube will
be used to remove a sample of the inner layer of the uterine
wall. Your provider will send the sample to the lab for
tests. You may have mild cramps during the procedure.
What happens after the procedure?
You may leave in a few minutes after the procedure is
completed. You may have some cramping and bleeding after
the procedure. Mild pain medicine should help relieve any
discomfort.
Ask your health care provider when you can expect to receive
the biopsy results. Also ask what steps you should take and
when you should come back for a checkup.
What are the benefits of this procedure?
