Objective：To explore a new screening way for early breast cancer，for the early discovery，early diagnosis and treatment of the disease. Methods：Retrospective analysis was made on the mammography screening of 3 107 women by our hospital from March 2010 to May 2011. Results：6 cases of breast cancer were detected by screening，with the detection rate of 193.11/100 000，all ranging from 40 to 60，including stage 0 DCIS in 1 case，stage Ⅰ in 4 cases，and stage Ⅱ in 1 case. Primary malignant lymphoma of the breast was in 1 case.Precancerous lesions was in 17 cases，including papillomatosis in 5 cases，ductal epithelial hyperplasia in 1 case，atypi－cal hyperplasia in 11 cases；the age of the screening targets was mainly between 40 and 49，which occupied 88%. Axillary accessory breast was in 629 cases，with the detection rate of 20.24%，and the incidence of accessory breast increased with the breast density． Conclusion：The detection rate of this screening for breast cancer is high. Mammography in breast cancer screening is extremely im－portant so that treating all objects with mammography may improve breast cancer detection rate；color ultrasonography and clinical breast examination （CBE） can be taken as the joint inspection measures of mammography screening.
