Because of the scattered medical facilities in Hokkaido and the region's vastness, it is often difficult for patients (especially those with breast diseases) to visit a medical center. Such geographical conditions make it economically difficult for patients in this area. Considering Hokkaido's regional peculiarity, mammography and aspiration cytology (usually secondary screening) are performed immediately after the primary screening.<BR>As a result, during the past 15 years, 149 cases (0.15%) of breast cancer have been detected. The detection rate at initial screening was 0.24%, whereas that at subsequent screening was 0.10%. Interval cancer was found in eight cases. With regard to the detection rate of early lesions in cases of consecutive breast cancer, the rate for mass screening was higher than that for outpatients; 77.5% of cancers screen-detected in asymptomatic women were at an early stages.<BR>The present system of mass screening in Hokkaido is discussed in terms of regional peculiarity and various problems associated with the screening program itself. In conclusion, on the basis of our experience, we consider that examinations utilizing diagnostic imaging methods such as mammography should be introduced to enhance the effectiveness of mass screening.
