Hi Lia, My score was a 13 so I faced the same decision.  My oncologist also wanted me to do Taxotere following 4 treatments of A/C dose dense chemo.  I chose the AC but skipped the taxotere.  I just completed the chemo yesterday.  The side effects were not too severe.  I get headaches, some nausea, insomnia and fatigue.  I did have a bout with ulcerations at the juction of my esophogus and stomach which was severe enough for a 1 day hospital visit but my oncologist started me on a liquid called carafate which has been very successful. I had IDC and chose a modified mastectomy.  My margins and nodes were clear and I'm ER/PR positvie HER2 negative so I too could have gone either way.  The Doc told me the chemo gave me an additional 5% which for me was enough to decide to do the chemo.  I have never been a worrier regarding my health because I have always been in perfect heath.  This cancer was a shock to me as I was sure my results would be negative.  Now I'm not as confident and I worry about it coming back.  I also know that I would kick myself forever if I didn't do the chemo and it came back. Best of luck with your decision. Dianec
