How It Is Done
You will lie on your stomach on a specially designed table. Your breast will hang through a hole in the table. It will be compressed by a mammography machine under the table. A computerized mammography machine will take images to locate the area of concern.
Once the site is located, your breast will be cleaned. A local anesthetic will be injected to numb the site undergoing the biopsy. A very small incision will be made so the needle can be inserted into the area. It is left in place while more images are made. This is to be sure the needle is in the correct spot. When the correct placement is confirmed, tissue will be withdrawn. A small marker may be left at the spot so that the area can be identified if you need surgery. You will not be able to feel the marker and it will not set off metal detectors. After the biopsy, the area will again be cleaned and a pressure dressing will be put over it. A mammogram may be done after the biopsy.
For many women, the most difficult part of the exam is lying with their arms over their head or at their sides for up to 60 minutes. You cannot move because movement changes the location of the site undergoing the biopsy.
