Stereotactic Breast Biopsy

Stereotactic breast biopsy is a digital image guided test that helps the Radiologist (x-ray doctor) locate breast abnormalities and obtain tissue samples for diagnosis. Biopsies are done when a mammogram shows an abnormal questionable mass, calcifications, or distorted breast tissue.


The breast will be compressed, and numbed. Digital images will be taken. A probe is inserted into the breast only once through a ¼ inch opening by the Radiologist (x-ray doctor). Tissue samples are removed. A surgical clip is placed to mark the biopsy site. Mammogram images will be taken to confirm clip placement.
Procedure time: 60 minutes.
