What to Expect
You will be positioned lying face up on the examination table or turned slightly to the side. You will be required to remain still during the procedure. A local anesthetic will be injected into the breast to numb it. Using a transducer, the technologist or radiologist will locate the abnormal area.
A very small incision is made in the skin at the site where the biopsy needle is to be inserted. Using the ultrasound probe, the radiologist will insert the needle and advance it directly into the mass and remove tissue for sampling. The needle will be removed after samples of tissue are taken.
Most people have little or no discomfort during the biopsy. You may feel a slight pin prick from the needle or some pressure when the biopsy needle is inserted.
You should avoid strenuous activity for 24 hours following biopsy.
