PARIS – An AI computer model can diagnose and identify 10 of the most common types of brain cancer with the same accuracy as human doctors, researchers said Monday. More than 15 million people worldwide are diagnosed with cancer every year, and 80 percent of those will undergo surgery. In the United States alone more than 1 million cancer samples are biopsied annually, and each one must be analyzed and diagnosed by a pathologist, placing enormous strain on health services. Writing in the journal Nature Medicine, a team of U.S.-based experts described how they trained an AI algorithm to analyze brain cancers from more than 2.5 million images. They found that the computer was able to diagnose common cancers in under three minutes -- more than 10 times faster than a human expert.
