Red light may soothe radiation mouth sores
NCT ID NCT04251949
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether shining a red LED light on mouth sores caused by radiation therapy can help them heal. 28 people with head or neck cancer who already had mild sores received a 7-minute light treatment before each radiation session. The main goal was to see if the sores would get worse and require a feeding tube.
