That would be tough to call, I know when I started my treatment I was asked to be the first to trial a new protocol for the medication ethyol. It's main purpose is to protect your saliva glands against radiation. It had always been given by IV before but it made everyone extremely nauseated to the point they would quit taking it. They wanted to give it in an injection between the layers, just under the skin. There was a chance of some pretty nasty side effects but given all the options and discussing it with my family I opted to do it. I completed 40 treatments and was able to withstand the side effects, which proved to be minimal. To date this is how the medication is being administered to everyone. I had laryngeal cancer in it's first stage. I underwent 40 radiation treatments, post 6 months and the cancer is gone. For me I don't have any regrets but your situation sounds to be different. Wish you all the best and I would like to konw what happens. Mike
