AI in Breast Screening Cuts Later Cancer Diagnoses by 12%, Study Shows

Artificial intelligence reduced later breast cancer diagnoses by 12% in a major Swedish screening trial.
Researchers studied 100,000 women undergoing mammography between 2021 and 2022.
The trial compared AI-supported screening with standard double readings by radiologists.
AI flagged high-risk cases and assigned low-risk scans to single readings.
The study, published in The Lancet, found higher early detection rates with AI.
Early-stage cancers accounted for 81% of cases in the AI group.
Aggressive cancer subtypes fell by 27% compared with standard screening.
Lead author Dr Kristina Lång of Lund University said AI could ease radiologist workloads.
Experts stressed AI should support, not replace, human clinicians.
