A bipartisan bill that would standardize communication to women regarding whether they have dense breast tissue on mammography was introduced in both the U.S. House of Representatives and the U.S. Senate on October 25.
The Breast Density and Mammography Reporting Act (S 2006 and HR 4122) is sponsored in the Senate by Sens. Dianne Feinstein (D-CA) and Dean Heller (R-NV). In the House, it is sponsored by Reps. Rosa DeLauro (D-CT) and Brian Fitzpatrick (R-PA).
The bill would set a minimum federal standard, as designated by the U.S. Secretary of Health and Human Services (HHS), for notification about dense tissue and recommend that women discuss with their healthcare providers whether they would benefit from additional screening. It also directs HHS to study improved screening options for women with dense tissue.
In 2009, Connecticut was the first state to pass a bill mandating that women be notified if they have dense tissue and advised of supplemental screening options. Since then, 31 other states have passed their own versions of the legislation.











![A normal mammogram confirmed by three-year radiologic follow-up illustrates reader-marked regions of interest (ROIs) during (A) unaided (round 1) and (B) artificial intelligence (AI)–assisted (round 2) reading. Each colored dot represents an ROI for recall by a human reader. Readers could mark more than one ROI per case, represented by multiple dots of the same color. During AI-assisted reading, the AI system displayed three visible prompts: two with suspicion of malignancy scores of 35% (left mediolateral oblique [L MLO] and craniocaudal [L CC]) and one with a suspicion of malignancy score of 10% (right craniocaudal [R CC]), shown as polygonal overlays. Without AI, six of 10 readers (60%) marked a false-positive ROI. With AI assistance, this fell to two of 10 (20%). R MLO = right mediolateral oblique.](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/07/2026-07-14-radiology-mammogram-ai-auto-bias.H0bYO8QlWs.jpg?auto=format%2Ccompress&fit=crop&h=112&q=70&w=112)
