The Impact of Breast Density Reporting Laws on Women's Awareness of Density-Associated Risks and Conversations Regarding Supplemental Screening With Providers.

Objective: We conducted a national survey to understand the impact of state-level density reporting laws on women's level of density risk awareness and their engagement in conversations with providers regarding supplemental screening.

Methods: In all, 1,500 US women aged 40 to 74 years who obtained a mammogram within 2 years were surveyed in February 2018. The sampling design yielded 300 respondents in each of five groups categorized based on density reporting law features.

Interest in breast density reporting legislation has accelerated in the past several years, driven primarily by patients turned advocates under the mentorship and leadership of Are You Dense, Inc, and Are You Dense Advocacy, Inc. The history of the density reporting movement and the birth of education and advocacy nonprofits are described, along with how legislative efforts began. The decades of scientific research on dense tissue's masking effect and its being established as an independent risk factor for breast cancer are summarized.
