Summary

This study tests whether a special light therapy (photobiomodulation) combined with a mobile health app can improve dry mouth and quality of life in people who have had head and neck cancer and completed radiation. Sixty participants will receive either real light therapy or a sham placebo, plus the app, over 3 months. Researchers will measure changes in dry mouth, swallowing, mouth opening, and overall well-being.

Active substance: photobiomodulation (light therapy) device
What this could lead to: If it works, this could offer a non-drug way to reduce dry mouth and improve quality of life for head and neck cancer survivors after radiation.
What could go wrong: This is a small, early-stage trial with only 60 people. The light therapy may not provide lasting relief, and results may not apply to all patients.
