Summary

This study tests if proton radiation causes fewer side effects than standard photon radiation in people with head and neck cancer. About 400 adults aged 40 and older will receive either proton or photon therapy, plus possible chemotherapy. The main goal is to see if protons reduce problems like dry mouth, trouble swallowing, pain, and speech issues during the year after treatment.
