Ditto what Gary and Cathy said. You need to throw everything you can at this and aim for a currative response if possible. I briefly when we meet with my Father's MO the first time mentioned should we do all of this with the first occurrence as we will have nothing left if it returns. He informed me that you throw everything you can at cancer. You don't save anything for the "next time". As a doctor he said he wanted to cure my Father and the only way to do that was to aim with all of your ammunition and fire. Don't mean to be harsh here as sounds like your husband has been through alot and radiaton is no picnic - but it is your chance at trying to beat this thing.
Good luck and keep posting........
