Summary

This study compares proton beam radiation to standard photon radiation (IMRT) for people with head and neck cancer. The goal is to see if proton therapy causes fewer side effects, like painful mouth sores, by exposing less healthy tissue to radiation. About 108 adults with certain cancers (salivary gland, skin, melanoma, or head and neck) will be randomly assigned to one of the two radiation types.
