The final outcome of B5c lesions detected on VACB excisions

Abstract

Introduction: The introduction of Vacuum assisted core biopsy (VACB) has changed the management of screen detected mammographic abnormalities. Accurate preoperative diagnosis of invasive malignancy is important for pre operative staging and planning for appropriate surgical excision. The aim of this study was to identify VACB specimens where invasive disease could not be confidently ruled out (B5c), and compare results to final histology.
