Biopsies
When a screening or recall mammogram shows a breast abnormality, a stereotactic breast biopsy may be used to diagnose the mass or lesion. Stereotactic mammography pinpoints the exact coordinates of the abnormality, allowing the specially-trained radiologist to insert a small needle directly to the lesion and remove small tissue samples.
What to expect during a breast biopsy
A stereotactic biopsy is an outpatient procedure that generally lasts about 60 minutes. You will be asked to remove your clothes and jewelry and put on a gown. There are secure lockers for your use in the dressing room. During the procedure, you will either lie on your side or be seated in a specially designed chair. Several x-ray images of the breast will be taken and computer coordinates of the lesion will be established. A local anesthetic will be injected into the breast and the radiologist will guide a small needle to the lesion. Another image will be taken to confirm that the needle tip is within the lesion. Several samples of tissue will be removed. A small marker may be left at the site of the lesion to aid future procedures, if necessary. Once the radiologist has completed the biopsy, a small dressing will be applied to the skin and, if a marker is used, a mammogram will be performed to make sure it is in the right position.
How to prepare for a breast biopsy
On the day of your exam, do not use deodorant, perfume or lotion anywhere from the waist up. If possible, avoid scheduling your biopsy just before your menstrual period, especially if you have breast pain at that time. If you have breast implants, please inform the scheduler when making your appointment so that she can reserve the appropriate amount of time for your procedure.
What to expect after the procedure
A pathologist will study the tissue samples to diagnose the lesion. Your referring physician will be notified about the results and you will receive a phone call from either your physician or the nurse navigator who will discuss the results with you.
