Breast density notification laws have grown from the first state legislation in Connecticut in 2009 to a federally mandated update to the Mammography Quality Standards Act in 2019. The increasing recognition of limited mammographic sensitivity in women with dense breasts has led to greater utilization of supplemental screening ultrasound. Robust data support improved detection of small node-negative invasive breast cancers with adjunctive ultrasound. Digital breast tomosynthesis and other emerging modalities may also play a role in screening guidelines.
乳腺密度通知法规从 2009 年康涅狄格州的首个州立法开始发展，到 2019 年联邦政府对乳腺 X 线摄影质量标准法案进行了强制更新。越来越多的人认识到致密乳腺女性的乳腺 X 线摄影敏感性有限，导致更多地使用补充性筛查超声。大量数据支持通过辅助超声提高对小的淋巴结阴性浸润性乳腺癌的检出率。数字乳腺断层合成术和其他新兴模式也可能在筛查指南中发挥作用。
