Artificial intelligence (AI)-supported mammography identifies more cancers during screening and reduces the rate of breast cancer diagnosis by 12% in the years following, finds the first randomized controlled trial of its kind. The trial involved over 100,000 Swedish women, and its results are published in The Lancet.

The interim safety results of the MASAI trial, published in The Lancet Oncology in 2023, found a 44% reduction in screen-reading workload for radiologists. Additionally, a different early analysis of the trial, published in The Lancet Digital Health, found a 29% increase in cancer detection without an increase in false positives.

The full results of the latest trial show that AI-supported mammography also reduces cancer diagnoses in the years following a breast cancer screening appointment by 12%—a key test of screening program effectiveness.
