treatment option

I had a modified radical mastectomy and am trying to decide on treatment options.  My cancer was invasive ductal, 1.9 cm. My lymph nodes (sentinal + 6 nodes)were clear and there was a clean margin.  My choices are chemo (either AC or CMF)followed by tamoxifen, or just tamoxifen. The oncologist says the chemo increases my survival rate by only 2-3 percent.  Because of the low percent of benefit,I am leaning toward just the tamoxifen because of the side effects of the chemo,especially adriamyican,which has the potential for heart problems-a prominent health problem in my family.  I am currently seeking a second opinion,but would like to get as many opinions as possible.  Thank you.
