Hi @charlotte1953,,
Welcome. I had a different type of cancer than yours. Lumpectomy, AC and Paclitaxel chemo, 6 wks rads and on Tamoxifen. There has been another post today "Newly diagnosed, about to start Ac" which has a lot of the answers to your questions on it. Have a look at that one, there is some great info on it.
As @Sister has said, some people have a rough time and others not so much. It is scary at the start with all the unknown variables. I chose to proceed with the chemo as I had 5 lymph nodes that the cancer had spread to already and although my CT was clear for all other parts, the chemo was a bit of insurance to mop up any small strays that couldn't be detected as yet.
Check out the other thread and keep asking questions. Every one is here to help and support you.
xoxoxo.
