I am glad you made a choice, I can't say if it is right or wrong, but it is your decision!!! Any stats that shows it helps is worth it in my book
I was at 1A which was kind of a no brainer for most oncologists --there were no stats at all that showed that it helped at 1A and I was not going to put chemo in my body unless I knew it would help
so far I am doing ok---
good luck to you and I hope you have the same results that I have had!
