Sophia, I don't know what I would do in your shoes. The questions you are asking are questions you should be asking your doctors--they can give you answers better than us. We aren't doctors. It's perfectly reasonable to be asking about the tradeoff between treatment benefits and possible bad side effects at any point in cancer treatment but certianly in your situation where they are recommending reradiation for a recurrence.

Some questions might be whether the treatment will have any chance of permanently making the cancer disappear or just slowing it down? If the answer is just slowing it down, how much benefit does research show there is? How much chance it will even slow it down at all? If it does slow it down, what's the average extra time you get? Are the side effects so severe I could end up dying from them? What will you do to be sure they don't get life-threateningly severe? Those are the questions to take to your doctor. And be clear you want honest answers, even if the answers might be hard to hear.
