Welcome to Connect @coleva. I know how hard it is to wait for treatment to begin. I had head and neck radiation and the medical staff were insistent on making certain that oral issues are under control so as to avoid ill effects from the radiation. Hopefully the dental team will move along quickly to get things going for him. My tumor was more aggressive in nature by the time it was diagnosed so treatment moved along quickly. I was about 6 weeks after my surgery that my radiation/chemo started. I agree with maratay that the doctors can address your concerns about any delay.
