Stereotactic-Guided Breast Biopsy
Lumps or abnormalities in the breast are often detected by physical examination, mammography, or other imaging studies. However, it is not always possible to tell from these imaging tests whether a growth is benign or cancerous. A breast biopsy is performed to remove small pieces of tissue through a minimally invasive procedure involving a hollow needle—from a suspicious area in the breast and examine them under a microscope to determine a diagnosis. Image-guided needle biopsy is not designed to remove the entire lesion, but most of a very small lesion may be removed in the process of biopsy. In stereotactic breast biopsy, a special mammography machine uses ionizing radiation to help guide the radiologist's instruments to the site of the abnormal growth.
How does the procedure work?
Mammography is a low-dose x-ray system designed to examine breasts. The special mammography unit used to perform a stereotactic breast biopsy is a digital mammography machine. In digital mammography, as in digital photography, film is replaced by electronic detectors. These convert x-rays into electrical signals, which are used to produce images of the breast that can be immediately seen on a computer screen. Stereotactic mammography pinpoints the exact location of a breast mass by using a computer and x-rays taken from two different angles. Using these computer coordinates, the radiologist inserts the needle through the skin, advances it into the lesion and removes tissue samples.
