I am/was in exactly the same position as you. I even got a second opinion to see if I really needed chemo. I didn't want to go through all of it if I didn't have to. All precautionary. An insurance policy as one doctor described it. I did a lot of research and it really reduces the odds of it returning. Of course, there is no guarantee, but I have 6 kids still living at home and I can't risk not being here to take care of them. It was not fun at all, it literally does bring you to the brink of death and back. I was unable to function for about a week after each treatment. I completed chemo in January 2012 and radiation in March 2012 and I am glad I did it. I am feeling "back to normal." If it comes back now, at least I know I did everything possible to prevent it.
