Stereotactic biopsy

Any abnormality seen on the mammography is usually followed with a stereotactic breast biopsy - wherein a small sample of tissue is removed from the abnormal part of breast using a needle and the sample is later analyzed in the laboratory. A special computer is used to guide the needle to the spot of abnormality. Mammography and ultrasound help the radiologist trace the accurate spot to place the needle. This procedure is carried out on an outpatient basis and there is hardly any scar left behind following the procedure. An x-ray is taken to ensure that the right portion of the breast is centered to the window in the pad.
