Wire localisation biopsy of non-palpable breast lesions: reasons for unsuccessful excision

Surgical excision following needle-wire localization of nonpalpable, mammographically detected breast lesions is a very valuable diagnostic and therapeutic procedure. No further treatment is usually required after establishing an accurate histological benign diagnosis of indeterminate lesions on preoperative assessment. On the other hand, ductal carcinoma in-situ (DCIS) and early invasive cancer, properly excised, may sometimes require further management depending on specific histologic findings. An uncommon problem of this procedure is the failure to identify, localize or excise the breast lesion. In this review article, factors that contribute to the failed needle localization procedure are presented.
