South Dakota has become the 37th state to mandate that women be told of their dense breast condition and the associated risks.
The bill (HB 1124) was signed into law on March 5 by Gov. Kristi Noem and goes into effect on July 1.
South Dakota State Rep. Taffy Howard introduced the legislation due to the inconsistencies in density notification across the state and the lack of information about the risks associated with dense breast tissue.
South Dakota's state law follows the February 15 passage of federal legislation directing the U.S. Food and Drug Administration to develop reporting language to ensure that mammography reports and summaries received by patients and their providers include appropriate information about breast density.










![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)
