- A procedure in which a small sample of tissue is removed from the breast. An imaging device is used to guide a hollow probe connected to a vacuum device. The probe is inserted through a tiny cut made in numbed skin on the breast. The tissue sample is removed using gentle vacuum suction and a small rotating knife within the probe. Then the tissue sample is studied under a microscope to check for signs of disease. This procedure causes very little scarring and no stitches are needed. Also called vacuum-assisted biopsy and vacuum-assisted core biopsy.
