## Tool posts biological age estimate
Within seconds, the tool posts an estimate of how old your body appears to be.
## Tool tracks aging over time
Users can add new images to track how their biological age changes over time.
## Study published in The Lancet
Researchers published a study in The Lancet Digital Health showing the AI predicts cancer survival from photos.
## Biological age linked to cancer risk
Among 38,000 patients, those looking at least five years older than their age had a 21 percent higher death risk.
## AI tool tested in clinical trials
The tool is being tested in two trials: one for lung cancer patients and another for surgical complications.
## Key takeaway

Mass General Brigham's AI tool estimates biological age from selfies and links older-looking faces to higher cancer mortality risk.
