Google's AI system, better than human doctors?

Google says its new AI system can detect breast cancer more accurately than doctors. 

According to a study published in the journal Nature, the artificial intelligence system reduced false positives by 5.7% and false negatives by 9.4% for U.S. participants.

Among UK subjects, false positives were reduced by 1.2% and false negatives by 2.7%.

The study used the mammograms of women in the U.S. and UK Results show the AI system was more accurate even though it was working off of less information. It did not have access to patient histories or prior mammograms.

According to the American Cancer Society, mammograms miss about one in five breast cancers.

Breast cancer is also the second-leading cause of cancer deaths among women.

The AI system could help with a shortage in radiologists in places like the UK. 

A 2018 report from the Royal College of Radiologists says 75% of UK radiology department directors believe there aren't enough radiologists, threatening patient care.
