Had diagnostic mamm. told because biltateral focal assymetey. Did 3d mamm, left breast fine, they did right breast ultrasound also. Tech did real quick exam, radiologist back with results in less then 5 minutes said looked good come back in year. 3d mamm tech said that original mamm noted tissue changes so thats reason for call back, most liky scar tissue. Had reduction 10 years ago, all mamms done at same place past 10 years. Never call back before. Can scar tissue now show up after 10 years?
