Wire Localization
Use of Needle (wire) Localization
This procedure is performed when your breast cancer can be seen on a mammogram but cannot be felt. It is done in radiology before your surgery.
Step I - Radiology: To Find the Breast Cancer
In either a sitting or standing position, your breast will be positioned for a mammogram so that the exact location of the breast cancer can be found. Once the area has been accurately found, the radiologist will numb your breast with a local anesthetic. A needle is then inserted and a small wire is threaded through the needle so that the tip of the needle is near the abnormal area. Accurate placement of the wire is checked by mammogram and then the wire is securely taped in place and covered to prevent position changes. This part of the procedure may take from one to one and one half hours; it is usually scheduled a minimum of two hours before surgery.Most women report no pain, but sensations of pressure and pulling. Some women feel faint or dizzy. If you have any unusual symptoms or sensations, tell the technologist (the person positioning you for the mammogram) or radiologist (the doctor). The staff can best help you if they are aware of how you are feeling.
