New research of 175,000 women – the largest NHS study to date – on AI in breast cancer screening shows that AI detected more cases of invasive cancer, more cases overall, had fewer false positives, and recalled fewer women having their first scan than humans did.
For one part of the study, which St George’s Hospital took part in, it found that an AI-assisted system alongside specialist radiologists can detect more cases of invasive breast cancer, while reducing the time radiologists spend reading scans by almost a third.
Dr. Mamatha Reddy, radiology consultant for breast screening at St George’s Hospital, said: “Improving cancer detection and finding cancers earlier means we can treat people sooner and improve their outcomes and survival rates, and this study could pave the way in allowing technology such as AI to aid doctors.
“For the first time, using AI alongside specialist radiologists has increased our accuracy in spotting early signs of cancer, while cutting the time spent reading scans by almost a third - allowing us to focus more time on caring for patients.”
