Wire Localization Biopsy of the Breast

What is the test?

A wire localization biopsy is a type of surgical biopsy.

Sometimes an abnormal area will be seen on the mammogram that clearly should be tested for cancer or completely removed from the breast, but this area is not easily felt as a lump on examination. The mammography department can help your surgeon to find the area more easily by using a technique called "wire localization."

In this technique, the radiologists (who have had the benefit of seeing the abnormal area on your mammograms) mark the abnormality with a wire that is inserted under your skin into the area of breast that is causing concern. Right afterward, the surgeon can meet you in the operating room and can use the wire to find the abnormal spot in your breast so that he or she can remove it.
