Two Studies Test Google's Breast Cancer Detection Models in Real-World Clinics

Two studies evaluated Google's mammography AI system—introduced in 2020 but not yet deployed for live patient care—against real-world UK NHS clinical workflows. In retrospective testing on 116,000 scans, the system achieved higher sensitivity (0.541 vs 0.437) than the first human reader while identifying 25% of cancers initially missed by doctors. A live integration test across 12 clinics showed the system processed scans in under 18 minutes versus over two days for human readers, with comparable accuracy, though some clinicians reported distrust of the system's outputs.
