The primary modality for breast cancer screening is mammography. Recent investigations, however, have indicated that an insufficient number of life-threatening cases have been detected by mammography while mammography can often results in a large number of overdiagnoses. To make breast cancer screening more effective, potential factors that influence screening efficacy need to be elucidated. Breast density is one of limiting factors for breast cancer detection using mammography. In this article, influence of breast density on breast screening is explained. Current topics related to breast density, objective assessment of breast density using applications, revision of breast composition classification in Breast Imaging-Reporting and Data System Mammography fifth edition, and legislative movement regarding breast density in the United States, are also mentioned in this review article.
乳腺癌筛查的主要方式是乳房X线摄影。然而，最近的调查表明，乳房X线摄影检测出的危及生命的病例数量不足，同时往往会导致大量的过度诊断。为了使乳腺癌筛查更有效，需要阐明影响筛查效果的潜在因素。乳腺密度是使用乳房X线摄影进行乳腺癌检测的限制因素之一。本文解释了乳腺密度对乳房筛查的影响。这篇综述文章还提到了与乳腺密度相关的当前话题、使用应用程序对乳腺密度进行客观评估、《乳腺影像报告和数据系统乳房X线摄影第五版》中乳腺成分分类的修订以及美国关于乳腺密度的立法动态。
