Just got back home had MRI of my brain done today and I'm unofficialy all clear which is obviously really good news . I have been wrestling with the decision whether or not I should do the prophylactic radiation , I had pretty much decided to do it. But now doc asked me to do a clinical trial designed to prove survival rates are better with the treatment . They basically will do same low dose radiation except they avoid the area that controls short term memory, which would make the decision to do the treatment a lot easier basically elliminating side effects. The down side is of course if that area is where the loose cells are the treatment won't destroy them. People in the trial don't get to decide if they want whole treatment or new treatment avoiding that area , it's like receiving placebo medication. So now I really don't know which way to go any more, any advise will be greatly appreciated.
