Wire localization is performed prior to surgery for non-palpable lesions. A wire is inserted, usually with the help of ultrasound, with the point of the needle in or close to the lesion. If the lesion is not visible on ultrasound, the wire can be inserted using stereotactic or off-hand technique. After excision, the specimen is X-rayed to verify removal of the lesion.
Except for a small puncture in the skin from the needle, there is little discomfort associated with this procedure.
