A trial of mass screening for breast cancer using both mammography and physical examination (independently) was carried out in women over 50 years of age in Tokushima Prefecture. Breast cancer was detected in eight of a total of 950 examinees by mammography alone, and no cases of breast cancer were detected by physical examination. The detection rate of breast cancer was 0.84%, which is very much higher than that obtained by conventional mass screening using physical examination alone. The detection rate increased especially in the sixth and seventh decades of life. All eight detected breast cancers were in the early stage. Based on these results, it is recommended to employ mammography in breast cancer screening for asymptomatic women aged over 50 years.
在德岛县对50岁以上女性进行了一项同时使用乳房X光摄影和体格检查(独立进行)进行乳腺癌大规模筛查的试验。在总共950名受检者中,仅通过乳房X光摄影就检测出8例乳腺癌,而通过体格检查未检测出乳腺癌病例。乳腺癌的检出率为0.84%,这比仅使用体格检查的传统大规模筛查获得的检出率高得多。检出率在60岁和70岁年龄段尤其增加。所有8例检测出的乳腺癌均处于早期阶段。基于这些结果,建议在对50岁以上无症状女性进行乳腺癌筛查时采用乳房X光摄影。
