What is a Stereotactic Breast Biopsy?
A stereotactic breast biopsy uses computer-guided imagery to position a biopsy needle within the breast. In this special type of biopsy, the radiologist takes a sample of breast tissue so that the patient can avoid surgery. Plan to stay for 1½ hours. We will select the equipment that will provide the best access to the area of your breast that requires biopsy. We may select for you one that is like a regular mammography machine and you will be seated during the procedure. Another option is a table on which you can lie with your breast placed through an opening to make it accessible to the X-ray and biopsy equipment.
Note: Aspirin, Vitamin E, Advil (ibuprofen), Aleve (naproxen), anticoagulants (blood-thinning medications), Fish Oil and Omega-3 supplements should be stopped for at least 4 days before the biopsy. Please tell the Breast Health Center if you are taking any prescription anticoagulants.

During Your Procedure
- A staff member brings you into a private room where you change from the waist up and put on a robe.
- The technologist will position your breast in the machine and ask you to lie still. This may make your neck feel slightly stiff and uncomfortable.
- After X-rays of the affected breast are taken, the radiologist gives you a local anesthetic and then makes a ¼-inch cut so that the biopsy needle can be guided easily into your breast. The procedure is painless for most women, although you may feel some vibration or pressure when the samples are taken.
- Using the computer images as a guide, the radiologist gets several tissue samples through the needle. A tiny clip may be inserted through the biopsy needle to mark the area being sampled.
- After the biopsy is done, the technologist applies antibiotic ointment, Steri-Strips® (incision tapes), a Band-Aid®, and an ice pack.

Caring for Yourself at Home
- You may drive home alone after the procedure.
- Before you go, your technologist tells you how to care for yourself at home and gives you written instructions and supplies, if needed.
- Keep the ice pack on your skin for 20 minutes, remove it and place it in the freezer for 10 minutes. Repeat for 1 to 3 hours, depending on how easily you bruise. Placing the pack within your bra is the easiest way to keep it in place.
- You are encouraged to go home and rest. If you must return to work, you may. However, you should avoid any heavy lifting (no more than 10 pounds) or physical labor.
- Your biopsy results will be available within 2 - 3 days. You get the results from the Breast Health Center nurse, the radiologist, or from your referring doctor.
