Hi David,
I've just looked at Martin's home file and it is IMRT that he went for, he had to have a green mould of his head and torso made and the mould was clipped to the table during the radiation.
We went for that because as he was of unknow primary, this treatment seemed more thorough and target more places. They also said they thought it was less harmful to the taste buds and saliva glands in the long term. It will be a year next month since the first operation so i suppose it's still a bit too soon to judge but martin isn't too impressed. But I think he is doing well he can eat things as long as there is a sauce. That's not bad really.
