Artificial intelligence is now more accurate than doctors in diagnosing breast cancer from mammograms.
Google has developed an artificial intelligence system that can detect the presence of breast cancer more accurately than doctors. The program was trained to detect cancer using tens of thousands of mammograms from women in the United Kingdom and the United States. Unlike the human experts, who had access to the patient's history, AI had only the mammograms to go on. Compared to human experts, the program reduced false positives by 5.7% for US subjects and 1.2% for UK subjects. It reduced false negatives by 9.4% for US subjects and 2.7% for UK subjects. "This is one of those transformational discoveries you have in your hand, which could disrupt the way we deliver screening in terms of improving accuracy and productivity," professor Ara Darzi, one of the authors of the paper and the director of the Cancer Research UK Imperial Centre said.
The detection and diagnosis of breast cancer sits alongside other Google research that demonstrates how AI can help doctors to more accurately predict lung cancer and prevent serious eye disease. Dominic King from Google Health said: "Our team is really proud of these research findings, which suggest that we are on our way to developing a tool that can help clinicians spot breast cancer with greater accuracy."
