Underestimation of invasive malignancy on conventional core biopsy of breast

Vacuum-assisted biopsy (VAB) has established itself as the more sensitive diagnostic tool in the preoperative assessment of non-palpable breast lesions. The aim of this poster is to establish the underestimation rate of invasive malignancy on stereotactic 14 g wide-bore needle (WBN) biopsy of impalpable breast lesions presenting as microcalcifications.
