Dear Patty: A needle localization wire insertion biopsy involves using either a
mammography machine or ultrasound to identify the abnormality. The doctor then numbs the outer tissue of the breast and inserts a very small needle into the
correctCorrect (new formula) location. A wire is then guided into that location and left. The patient then goes to surgery and the area around the wire is removed. The breast is stitched up and the patient goes home. Most
womenWomen's way tolerate the procedure with minor discomfort.
