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.
For a surgical biopsy, the surgeon makes an incision in the skin and removes all or part of the abnormal tissue for examination under a microscope. Unlike needle biopsies, a surgical biopsy leaves a visible scar on the breast and sometimes causes a noticeable change in the breast's shape. It's a good idea to discuss the placement and length of the incision with your surgeon beforehand. Also ask your surgeon about scarring and the possibility of changes to your breast shape and size after healing, as well as the choice between local anesthesia and general anesthesia.
