What is a stereotactic breast biopsy?

Advanced computer imagining technology is used to map the precise location of the area of interest in the breast that was previously seen on the mammogram or by ultrasound.

With the use of technology, the physician is able to remove a small area of tissue. Once the tissue is removed, it is sent to a pathologist who will analyze the tissue for diagnosis.

The procedure takes approximately one hour.

Preparing for the Procedure

On the day of your procedure, you will be asked to undress from the WAIST UP and will be given a gown to wear.

The technologist will position you face down on a specially designed table with your breast placed through an opening in the tabletop. The tabletop will be raised and the physician and technologist will perform the procedure from beneath the table.

During the Procedure

Your breast will be slightly compressed and held in a fixed position to ensure the accuracy of the procedure. X-ray images will be taken, and special software will map the exact location where tissue samples will be taken.

The skin over the biopsy area will be cleansed with disinfection soap and numbed with a local anesthetic injected into the breast with a small thin needle.

A small incision will be made and the biopsy instrument will be inserted. You may feel some slight pressure during this time and may hear a “click” from the biopsy device.

Once the physician has taken the needed biopsy samples, the biopsy probe is removed from the breast.
