Laser light may soothe chemo mouth pain in kids
NCT ID NCT02604329
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether a low-level laser can be used to treat painful mouth sores caused by chemotherapy or radiation in children with cancer. The laser was applied to the inside of the mouth every two days while sores were present. The main goal was to see if the treatment could be given at least three times in the first week. Only 22 children took part, and the study did not compare the laser to any other treatment, so it cannot say if the laser actually helps.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
low-level laser therapy (Oncolase Digi device)
What this could lead to
If this approach works, it could offer a non-drug way to ease mouth sore pain and speed healing in children undergoing cancer treatment.
What could go wrong
This is a very small feasibility study (22 children) with no control group, so it cannot prove effectiveness. The procedure may be difficult to apply consistently in young, sick children.
