Glow-in-the-dark mouth checks could catch cancer early

This study tests whether shining special lights in the mouth can help spot early signs of oral cancer. About 338 people at higher risk for mouth cancer (such as those with white or red patches, heavy tobacco use, or certain conditions) will have their mouth tissues examined with fluorescence imaging and spectroscopy. The goal is to see if these light-based methods can detect pre-cancerous or early cancerous changes better than standard white-light exams, potentially allowing earlier and easier treatment.
