The Affordable Care Act (ACA) increased the number of diagnoses of early-stage colorectal cancer by 8% among U.S. seniors ages 65 and older between 2011 and 2013, according to a study published in the January issue of Health Affairs.
Study authors Nengliang Yao, PhD, and doctoral candidate Brett Lissenden used information from the Surveillance, Epidemiology, and End Results (SEER) program, which consolidates cancer data from 18 different registries (Health Affairs, January 2017, Vol. 36:1, pp. 101-107).
The researchers also found that the ACA had no noticeable effect on the number of diagnoses of early-stage breast cancer over the same time period, which they attributed to the fact that the decrease in out-of-pocket spending was greater for colorectal screening than for breast cancer screening.
Yao and Lissenden's research contrasts with a study published January 9 in Cancer, which found that the ACA increased compliance with mammography screening by eliminating out-of-pocket costs, but it did not increase colonoscopy rates among poorer patients.











![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)
