Core Needle Biopsy
If a lump has been found through examination, mammography or ultrasound, a core needle biopsy may be used to diagnose the abnormality. The
needle has a large center that removes a core of tissue from the lump. Core biopsies may be used with ultrasound to guide the physician
to the suspicious area. The procedure is performed in the breast center.
The skin where the needle will be inserted is cleaned with an antiseptic to destroy bacteria. The area is then numbed by injecting an anesthetic
agent through a small needle. The physician locates the lump and stabilizes it to prevent movement as the core needle is inserted.
Since the needle is large, you will feel pressure as the physician inserts the instrument. The needle removes a core of tissue which
is sent to the pathology lab for evaluation. The pathologist informs your physician of the results of the biopsy, whether it is benign
or malignant. Ask your physician when and how you can expect to receive the biopsy results.
The procedure takes about 15 minutes. When completed, a small bandage will be placed on your breast and you can return to your normal
activities. You may shower the same day as your biopsy.
If a hematoma forms after the biopsy, inform your physician. This occurs from rupture of a small blood vessel during the procedure,
and causes a tender lump and often bruising.
