Wire localization is a technique that is used to mark the location of a breast abnormality that is quite small, or that can’t be easily found by touch. This procedure ensures greater accuracy for removal of the abnormal lesion. The wire will be a guide to accurately locate the tissue that needs removed.
The wire localization will be done at the Radiology Department. Your breast will be numbed with local anesthetic before placement of the wire. A mammogram is used to indicate the location of the breast abnormality. Special equipment such as a paddle-shaped compression device may be used during your mammogram. It may be necessary to take several images in order to find the exact location of your lump or area of cancer.
Inserting the wire
Once the mammography images have been obtained and the breast numbed, the radiologist will use a very fine needle to target your breast abnormality. The tip of the needle must rest in the location that your surgeon needs to find in order to remove the right tissue. A slender wire is then threaded down through the needle and out of its tip to lodge in the target tissue. The needle will then be removed, leaving the wire in place.
