The purpose of this study is to evaluate the diagnostic accuracy of breast cancer from mammography images and to investigate the characteristics of patients who was diagnosed as a breast cancer. The subjects for this study were 85 patients who underwent breast imaging test with screen-film method and investigated from March 2010 to October 2010. The average age of the subjects is 51.9 years old. The 43.5% of onsets were located at the upper outer quadrant (UOQ). In terms of the age group, group for 40-49 ages were highest 37.6 (32/85)%. As for breast composition, fatty and dense breast were 30.6% (26/85) and 69.4% (59/85) respectively. The average age of the patients with fatty breast is 62.4 years old, whereas those with dense breast was 46.5 years old. The false negative rate of mammography images was 27.1% (23/85) and the sensitivity of mammography was 72.9% (62/85). The false negative rate of the patients with dense breast was 32.2% (19/59). the sensitivity of them was 67.8% (40/59).
