Artificial intelligence spots more skin cancers than experts

Artificial intelligence is better than doctors at spotting skin cancer, a study has shown. A Google algorithm devised to recognise unusual moles not only picked up more cancers but also ruled out more benign lesions. Experts are increasingly optimistic that within a few years machine learning will automate many diagnoses, helping doctors to become more efficient and reducing mistakes. Last week Theresa May said AI that harnessed genetic information and medical records to spot disease early was crucial to Britain's future prosperity. The latest study, led by Professor Holger Haenssle, of the University of Heidelberg, is one of the first in which AI convincingly comes out on top against specialists in spotting cancer.
