This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
After radiation therapy for head and neck cancer, some patients develop long-term side effects like neck stiffness, difficulty swallowing, and tissue scarring. This trial is testing photobiomodulation (PBM), a treatment using special light-emitting diodes applied to the skin of the neck and face, to see if it can reduce these side effects. Half of the participants will receive active light therapy, and half will receive a sham (fake) treatment so researchers can compare the results fairly.
Radiation fibrosis syndrome—the stiffness, scarring, and swallowing problems that can follow neck radiation—is a common problem that can persist for years and affect quality of life. While early research suggests this light-based treatment may help prevent mouth sores during radiation, there is limited evidence about whether it can treat scarring and swelling that has already developed.

If you join, you'll be randomly assigned to receive either active light therapy or sham (fake) therapy applied to 12 sites on your neck and face. You'll have treatment sessions at two different time points after your radiation finished. Each session involves positioning the light device against your skin in the scarred or swollen areas, similar to other outpatient procedures. The study team will measure changes in your neck tissue thickness and symptoms over time to see if the light therapy helps reduce stiffness, swelling, and other side effects.
