An AI tool analyzes cancer patients’ facial expressions and outperforms doctors in predicting their prognosis. Scientists have developed FaceAge, an AI capable of scanning a cancer patient’s face and more accurately predicting short-term survival compared to human doctors. Trained on nearly 59,000 healthy faces and tested on 6,196 cancer patients, the algorithm identifies “biological age,” which is often older than a patient’s actual age. The older the face appeared, the poorer the prognosis. When doctors relied solely on photos, their predictions for 6-month survival were accurate 61% of the time. However, when FaceAge was introduced, the accuracy increased to 80%. While concerns about bias and confounders remain, it is undeniable that AI has the ability to discern mortality from a person’s face.
