Follow-up of palpable circumscribed noncalcified solid breast masses at mammography and US: can biopsy be averted?

Purpose: To determine whether palpable noncalcified solid breast masses with benign morphology at mammography and ultrasonography (US) can be managed similarly to nonpalpable probably benign lesions (Breast Imaging Reporting and Data System [BI-RADS] category 3)-that is, with periodic imaging surveillance-and to determine whether biopsy can be averted in these lesions.

Materials And Methods: No institutional review board approval or patient consent was required. This retrospective analysis, based on final imaging reports, included 152 patients (age range, 28-77 years; mean age, 48.
