Safety of vacuum-assisted biopsy/mammatome guided, non-operative management of B3 lesions without atypia: a 7-year follow-up study

B3 management balances safe treatment of potential malignancy against the morbidity of surgical excision of benign lesions. Vacuum-assisted biopsy (VAB) increases diagnostic accuracy, removing some lesions entirely without surgery. Few follow-up data are available to assess the safety and effectiveness of this approach.
