Introduction
For several years our breast unit has evaluated indeterminate breast microcalcification using stereo-guided vacuum-assisted core biopsy (VACB) - piecemeal acquisition of unorientated tissue. The Intact Breast Lesion Excision System (Intact) removes a single larger piece of tissue, potentially allowing pathologists to calculate margins and visualise lesion architecture more easily. This study evaluates the role of the 20 mm Intact in assessment of subcentimetre clusters of indeterminate breast microcalcification.
