Chinese researchers have developed an artificial intelligence system to diagnose cancerous prostate pathology samples. Confirmation of a prostate cancer diagnosis normally requires a biopsy sample to be examined by a pathologist. The ML team took 918 prostate samples from 283 patients and ran these through the system, with the software gradually learning and improving diagnosis. The pathology images were subdivided into 40,000 smaller samples of which 30,000 were used to train the software while the remaining 10,000 were used to test accuracy. The results showed an accurate diagnosis in 99.38 per cent of cases, using a human pathologist as a gold standard.
