マンモグラフィ検診による乳癌死亡率減少効果と本邦の乳癌検診の課題

In Japan, breast cancer screening had been done by physical examination alone. Mammographic screening has been effective for women aged over 50 years in Japan.When mammographic screening is introduced to the screening for breast cancer, how to control the quality of screening is an important problem and it seems necessary to control the qualities of imaging and data analysis. In the Japan Association of Breast Cancer Screening, a central committee on quality control for mammographic screening was established with cooperation of related medical societies. This committee including the education/training subcommittee and facility/image assessment subcommittee was the first system for the cancer screening since such system has not been established in the cancer screening of other organs in Japan.
