AI system 'near perfect' at spotting prostate cancer

In another step toward using artificial intelligence in medicine, a new study shows that computers can be trained to match human experts in judging the severity of prostate tumors. Researchers found that their artificial intelligence system was "near perfect" in determining whether prostate tissue contained cancer cells. And it was on par with 23 "world-leading" pathologists in judging the severity of prostate tumors. No one is suggesting computers should replace doctors. But some researchers do think AI technology could improve the accuracy and efficiency of medical diagnoses.
