29%more cancers, 44% less workload
Because of AI, Swedish mammography screening found 29% more cancers with 44% less radiologist reading time, and 12% fewer cancers surfaced between screens.
MASAI, the first RCT of AI in cancer screening (105,934 women; Lancet, Jan 2026), reported interval cancers of 1.55 vs 1.76 per 1,000 with AI-supported reading vs standard double reading, with fewer invasive, T2+, and non-luminal-A interval cancers, on top of earlier results showing higher detection and lower workload at the same specificity.
