Are you trying to decide which to do? For me, I would ask the Dr. which I need. I don't like being the one to decide which is best, I didn't go to school to be the Dr. He did. So I want to be told, with confidence, that I need "this" treatment. Because it would be the best thing to do.
given that, if I still had to decide, I would take the Radiation over the chemo, just because it's easier. but if there is any doubt that the chemo would do a better job. I'm taking the chemo.
Best of luck to you, I hope its a quick and easy treatment for you, whichever you choose.
