What is an endometrial biopsy?
An endometrial biopsy is a way for your doctor to take a small sample of the lining of the uterus (endometrium). The sample is looked at under a microscope for abnormal cells. An endometrial biopsy helps your doctor find problems in the endometrium.
Why is an endometrial biopsy done?
An endometrial biopsy is done to check for abnormal cells in the lining of the uterus (endometrium). It checks for precancerous and cancerous cells. It may be done if you are at higher risk for uterine cancer or have symptoms of uterine cancer, such as abnormal bleeding from your uterus.
How is an endometrial biopsy done?
- You will lie on an exam table. Your feet will be in footrests.
- The doctor will use a tool called a speculum to see the cervix.
- The doctor may use a spray or injection to numb your cervix. The cervix is the opening to the uterus.
- Then the doctor will pass a thin tube through the cervix to take a sample of the uterus lining.
- The sample is sent to a lab.
How do you prepare for an endometrial biopsy?
- If you take aspirin or some other blood thinner, ask your doctor if you should stop taking it before your test. Make sure that you understand exactly what your doctor wants you to do. These medicines increase the risk of bleeding.
- Ask your doctor if you should take a pain reliever, such as ibuprofen (Advil or Motrin), 30 to 60 minutes before the test. This can help reduce any cramping pain that the test can cause.
What do the results of an endometrial biopsy mean?
Lab results from a biopsy may take several days to get back.
