Wide bore needle biopsy: see core cut biopsy entry.
Wire localisation biopsy: a form of surgical biopsy of a non-palpable lump or area of microcalcification that requires the placement of a wire to mark the site. The wire is placed under local anaesthetic using mammographic techniques or ultrasound, where appropriate, in the Department of Imaging. The abnormality is then excised with a cuff of normal surrounding breast tissue, usually under general anaesthetic, in the operating theatre. The surgical specimen is X-rayed to confirm completeness of excision, orientated and sent for histology.
