Stereotactic breast biopsy
A Stereotactic breast biopsy is a medical test which can identify the cause of a calcification or an abnormality in the breast. A radiologist performs this procedure in the radiology department. During the procedure, the radiologist inserts a needle into the abnormal area under the imaging guidance (mammogram) and removes a sample of the tissue, which is given to a pathologist, who looks at it under a microscope. The pathologist can determine what the abnormal tissue is: cancer, non-cancerous tumor, infection, or scar.
