Four years ago this month I was in the same position you're in right now (stage 2, clear margins, micro-met in one node). For two weeks I prayed so hard that my oncotype no. would be low and I could avoid chemo. It ended up not being a terrible no., but it was high enough that my onc. recommended chemo. I was so disappointed, but I went ahead with the chemo.
Looking back, it was the right decision for me. If the cancer ever comes back - and that is a possibility for all of us - I won't blame myself for not doing all I could the first time around. And, like Cheryl said, while chemo is not fun, it is do-able.
Everyone is different, and you will have to decide what is best for you, regardless of oncotype number you end up with. Your dr. will be able to give you some good insights when he/she knows more.
God's blessings with whatever you choose. You will be fine.
