Can a simple photo of your face reveal how ill you are?
Summary
Researchers in the US have developed an AI tool that can analyze a single photo of a person's face to estimate how ill they are and predict how long cancer patients might live. The tool looks closely at areas around the eyes and nose and is designed to help doctors, not replace their judgment.Key Facts
- The AI, called FaceSurvival, uses photos of 35,000 cancer patients and millions of healthy faces to learn how to estimate illness severity and survival chances.
- Key facial features used include the skin under the eyes and around the nose bridge.
- The cancer patients studied were mostly between their 50s and 60s, but also included children and older adults.
- The AI tool is still in early testing and not yet suitable for hospital use.
- Another tool, FaceAge, predicts biological age by analyzing facial wrinkles and lines.
- Lifestyle factors like smoking and drinking can influence how the AI estimates biological age.
- The AI works consistently across different lighting, facial expressions, and some cosmetic surgery effects.
- Researchers need more data, especially from diverse ethnic groups, to improve the tools.
- The public is invited to upload photos to receive a personalized biological age estimate.
