Hookwire localization and excision of lumps
Mammograms and ultrasound examinations often pick up lumps and other findings that we can’t palpate on self examination or even a doctor’s clinical breast examination. If these are deemed abnormal it should be excised. So, simply put, hookwire localization is a way to locate these non-palpable lumps/findings, so that it can be excised.
Typically on the day of surgery the doctor inserts a fine wire through this lump. This may be done under local anaesthesia. The insertion is usually guided by ultrasound, mammogram or MRI. The hook ensures that the wire stays in place.
This wire serves as a marker for the surgeon who will then use this as a guide to remove the lump under general anaesthesia.
