Beating the cancer backlog is AI's largest test yet

They had been staring at a mammogram for several minutes, and couldn't work out what was wrong. They sent the scan on to an arbitrator radiologist who declared that it was clear. That's when Mia, an artificial intelligence (AI) system developed by British start-up Kheiron Medical, stepped in. The AI immediately highlighted in green an area of concern, a pair of grey clouds which appear to the human eye exactly like the rest of the scan. This section of the scan, Mia concluded, was a sign of cancer.
