Hi Everyone, New to this whole thing. My dad just got out of surgery for his mouth cancer. They are saying they found cancer in his lymph nodes and it is an aggressive cancer so we are now going to have to do Radiation and Chemo. I am starting to research about Radiation and have come across some different methods. One being IMRT (intensity Modulated Radiotherapy) as well as Radioimmunotherapy both which seem to lessen the damage to the salivary glands. I was wondering on any advise on what radiation treatment people have used
