Sixty-five-year-old female mammography CC and MLO views ACR C .Bilateral central partially well-circumscribed partially obscured dense lesions, BIRADS 3. Lt upper central and UOQ area of focal asymmetry and architectural distortion, BIRADS 3. Tomosynthesis CC and MLO views right central rather well-circumscribed dense lesion, BIRADS 2. Left upper central irregular speculated lesion BIRADS 4C. 3D digital breast tomosynthesis easily detected the lesion and this changed the BIRADS from 3 to 2, proved by US to be cyst, tomosynthesis upgraded the left central lesion which was proved to be duct carcinoma by biopsy
