Could less radiation be better for head and neck cancer patients?

This study tests whether giving less radiation after surgery for certain head and neck cancers can reduce long-term side effects, like trouble swallowing, without allowing the cancer to come back. About 508 adults who have had surgery and need standard post-op radiation will be randomly assigned to either the usual radiation or a reduced version that skips some neck areas. The goal is to see if the gentler approach leads to fewer feeding tube dependencies and similar cancer control.
