Stereotactic breast biopsy

While mammography is an excellent way to detect breast abnormalities, in many cases, it is difficult to determine whether an abnormality seen on a mammogram is benign or cancerous. A stereotactic breast biopsy is used to take samples when a mammogram shows a breast abnormality, such as:

• Suspicious solid mass
• Microcalcifications, a tiny cluster of small calcium deposits
• Distortion in the structure of the breast tissue
• Area of abnormal tissue change
• New mass (or area of calcium deposits) at a previous surgery site

During a stereotactic breast biopsy, a special mammography machine uses ionizing radiation to precisely guide the radiologist to the target area. Two-dimensional digital images of the breast are taken from two different angles and sent to a computer for analysis. The computer compares the data from each image and calculates three-dimensional location coordinates for the breast abnormality. With such precise information to guide the biopsy needle, a doctor or radiologist can accurately sample fluid or tissue.

Bring your physician's orders, insurance card and picture I.D. with you on the day of the exam. Family members are invited to stay in our waiting area for the duration of your procedure.

After you change into a patient gown, the technologist will ask you to lie face down on a special examination table, making sure you are as comfortable as possible. Your breast will be positioned through a special round opening in the table. The table will then be elevated so the physician and technologist can perform the biopsy from below. The first part of the procedure will be much like your mammogram.

The physician will then administer a small amount of local anesthetic to minimize any pain. Most patients describe feeling pressure in the area as the biopsy is being performed. Multiple samples may be obtained.

When the procedure is finished, the nurse or technologist will apply pressure to the biopsy site for five to ten minutes to prevent bleeding. Afterwards, a dressing will be applied which you will wear home. You will then be given some post-procedure care instructions.

Most people feel fine after the procedure and are able to return to their normal routine soon after. However, we recommend that strenuous exercise or activity be avoided for at least 24 hours. If possible, it's not a bad idea to go home and relax after the procedure.

A pathologist will examine the tissue samples and a typed report will be sent to your physician within 3-5 days from the time you were examined.
