Objectives: To determine the accuracy for detection of breast cancer by mammography and ultrasonography correlate with histopathology and unchanged follow up mammographic reports in 2 years.

Materials and methods: Retrospective study of 2,766 mammographic reports with BI-RADS classification into BI-RADS 1 for negative study, BI-RADS 2 for benign finding, BI-RADS 3 for probably benign lesion, BI-RADS 4 for suspicious malignancy and BI-RADS 5 for highly suggestive of malignancy. All patients had been confirmed diagnosis with tissue histopathology or unchanged mammographic reports up to 2 years.
