Needle Localization

A needle or wire localization is a pre-surgical procedure in which a wire is inserted, via a hollow needle into an abnormal area of tissue which can then be surgically sampled. It is used to localize either a mass or calcification which cannot be felt on physical examination. An imaging device such as an ultrasound probe is used to help place the wire in or around the abnormal area. You will then be taken to the operating room where the surgeon will remove the targeted tissue. The tissue will then be x-rayed to ensure the correct tissue was removed and then sent to Pathology where the tissue will be evaluated.
