A recent study published in The Lancet found that using AI in breast cancer screening reduces the rate of later cancer diagnoses by 12%. The study, conducted in Sweden between April 2021 and December 2022, involved 100,000 women and compared AI-supported mammography with standard radiologist readings. The AI system analyzed mammograms, prioritizing high-risk cases for double readings and highlighting suspicious findings. Results showed a higher rate of early cancer detection and fewer aggressive cancer subtypes in the AI-supported group. Researchers suggest AI could reduce radiologist workload and improve early detection, but emphasize the need for careful implementation and monitoring.
