Non-mass lesions detected by breast US: stratification of cancer risk for clinical management

ConclusionOur classification system which incorporates US and mammographic features of breast NMLs can help interpret and manage all NMLs detected on breast US by stratifying cancer risk according to BI-RADS categories.Key Points• When diagnosing breast NMLs detected on US, suspicious US features are segmental distribution, associated abnormal ductal change, calcifications, and posterior shadowing within or around the NML on B-mode US, while a probably benign US feature is the presence of multiple small cysts.• Corresponding suspicious mammographic features of breast NMLs detected on US are associated calcifications and focal asymmetry.• Our classification system which incorporates US features with and without mammography can potentially be used to interpret and manage any NMLs detected on breast US in clinical practice.
