AI could spot mouth cancer early from a simple photo
NCT ID NCT07529769
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study will collect thousands of photos of mouth lesions from patients seen over 50 years at a French hospital. Experts will review each photo to confirm the diagnosis. Researchers will then use these images and patient data to train an AI system to automatically identify cancerous and precancerous lesions. The goal is to create a tool that helps doctors detect oral cancer earlier and more accurately.

- Active substance
- Artificial intelligence algorithm
- What this could lead to
- If successful, this AI tool could help dentists and doctors spot oral cancers earlier, potentially improving survival rates.
- What could go wrong
- This is an early-stage development study using historical photos. The AI may not work as well in real-world settings or on diverse populations.
