I totally understand your thoughts. I am 73 and have had a good prognosis with surgery, neg. nodes and clear margins with a very small, early detection. Chemo now due to my onco score being 31. Half way through chemo, it was so hard that I talked to my oncologist saying I wanted to quit because of the time and challenges this has caused. Long story short, he has given me an option for the 3rd treatment that may help the horrendous chemo reactions that I have had so I will go for one more of the 4 they are planning. I would say, weight your options. You don't say where you are on that journey, but I understand where you are coming from. I decided to take them one at a time and decide then. I am planning to do the radiation thinking that cannot take nearly the time or the side effects chemo has been. But, again, I had no idea how hard the chemo was going to hit me either. Probably naive. Anyway, the thought of this coming back is so frightening it spurs me on. God bless you. I know he will guide you.
