Preoperative Wire Localization
When a lumpectomy is planned, we need to be able to remove the cancer with a small amount of surrounding tissue. If the cancer is not palpable — was detected by mammography, ultrasound or MRI — the surgeon needs a guide to know where to go to find the cancer.
About the Procedure
On the day of your surgery you will be asked to go to Room 300 of the Nelson Clinic (on the third floor, across from the elevators) so that a small wire can be placed through the cancer using mammographic or ultrasound guidance. The wire stays in your breast long enough to serve as a road map for the surgeon to find and remove the cancer.
After the wire is placed in your breast, you are transported to the surgical waiting area in a wheelchair.
While you are still in the operating room, the tissue that is removed will be brought back to breast imaging and an X-ray image can be done to confirm that the abnormality has been removed from your breast. We will also make sure that the wire used to localize the lesion has been removed from your breast and we mark the location of the abnormality in the specimen so the pathologist knows where they need to focus their attention in analyzing the specimen.
