Having a hard time making decision on having chemo or not

redlessi

I am 51 years old. I went for my annual routine mammogram with required additional views. That required a steriotactic biopsy and pathology showed IDC and DCIS. I had lumpectomy on 11/25/13 and sentinal node biopsy which showed negative nodes but unclear margins. I had re-excision lumpectomy 1/3/14. My tumor was 1.9cm. ER and PR positive but Her2 negative, Stage 1 grade 3.  I had the onco test with gave me a score of 26 with recurrence risk of 17%. I am going to receive a total of 34 radiation treatments, 5 times a week for 6 weeks. The medical oncologist said I am in the intermediate or gray area as far as the benefits or risks of chemo. I am also to receive hormone therapy after radiation. Is there anyone here that declined chemo? What were your results? Just looking for some folks with similar situations to offer some feedback.
