Management of B3 Lesions—Practical Issues.

Purpose of the Review: Breast lesions of uncertain malignant potential (B3) are a heterogeneous group of diagnostic entities that can be associated with atypia. These are associated with in situ or invasive malignancy in 20–30% of cases. The management of those lesions has been both controversial and challenging for the multidisciplinary teams. Recent Findings: This is an up-to-date review of the current International Consensus on the management of B3 lesions with emphasis on the practical considerations. Summary: Through multidisciplinary management pathways, the vast majority of B3 lesions should be managed by vacuum-assisted excision, rather than surgical excision. Exceptions to this pathway and the rationale for surgical excision are discussed. [ABSTRACT FROM AUTHOR]
