United Kingdom, Oct. 20 -- Doctors have developed an artificial intelligence system that can predict a cancer patient's chances of survival from a single photograph of their face.

The technology, developed by researchers at Mass General Brigham in Massachusetts, was trained using more than 40 million facial photographs spanning different ages and ethnicities.

Details of the research were published in The Lancet Digital Health.

The system, known as FAHR-Face, was used to create two complementary tools. FAHR-FaceAge estimates a person's biological age, based on how old they appear, while FAHR-FaceSurvival predicts cancer survival directly from a facial photograph.

The researchers found that the two tools drew on different areas of the f...
