AI Selfie Cancer Test: Can One Photo Predict Survival?
Can a simple selfie tell a doctor how strong a cancer patient really is? It sounds like science fiction, but a new study suggests the answer may be closer to "yes" than we think. Researchers at Mass General Brigham in the United States have built an artificial intelligence tool that can estimate a person's biological age and predict a cancer patient's chances of survival from a single photograph of their face. This is one of the most detailed demonstrations so far of AI in healthcare using an everyday photo. The model was trained on more than 40 million facial images across many ages and ethnicities, and the results were published in the medical journal The Lancet Digital Health . This guide explains what the new AI selfie tool is, how it reads a face, what the study found, why doctors are interested, and why experts say more research is still needed.
