What is Needle Core Biopsy?

Needle core biopsy is a procedure where a "core" (sample) of breast tissue is removed by a biopsy needle for a Pathologic evaluation. Usually 5 to 6 "cores" of tissue are removed from the area needing biopsy. A Pathologist can look at these pieces of tissue and make a histologic differentiation. This prevents the need for an open surgical biopsy on many patients. Lidocaine is used as a local numbing to avoid any discomfort.

A registered technologist, dedicated exclusively to breast imaging, will assist the Radiologist in your procedure. The technologist will review your films for image quality, which includes proper positioning, adequate compression and visualization of all of your breast tissue.

Your procedure will be interpreted by a Radiologist who specializes in the interpretation of breast imaging studies. The Radiologist will review your films and generate a report. The report will be sent to your referring physician.

Preparing for your visit:

Please do not use deodorants and powders before your mammogram. These products contain chemicals which can interfere with test results.

Clothing:

You may want to wear separates, such as a skirt and blouse, to simplify undressing for your mammogram.

After your exam:

Please take it easy for the next 24 hours after your procedure and do not lift anything heavy.
