PB.33: Vacuum-assisted biopsy for lesions of uncertain malignant potential: further evidence of its suitability as a safe alternative to surgery

Increasing evidence supports vacuum-assisted biopsy (VAB) instead of surgical excision for the management of lesions of uncertain malignant potential (B3). This followed reports of up to 34% upgrade to malignancy on excision. In January 2012, regional guidance was adopted to clarify the options for managing such lesions. In our department, we have used similar local guidelines since 2011. We report our analysis of the management of B3 lesions before and after the introduction of VAB.
