Re: Chemo or not?
Now days 6 nodes is actually quite a few for an early stage cancer, so I think they have been very cautious.
Re: Chemo or not?
Molly - the doctors weight the benefits vs. the risks of chemo. Taking out 6 nodes is quite a bit and typically breast cancer would move to the sentinel (first) nodes initially. I also had Stage 1, grade 1 BC. It was just a bit larger than yours and my Mammaprint was similar to your Oncotype. Many doctors do not use the Ki-67 in calculating benefit of chemo as studies have not shown a benefit and Oncotype is considered more accurate.
If you are concerned you can always get a 2nd opinion. I am older than you (63 at diagnosis) but even with my genetic mutation that causes a high risk for breast and ovarian cancer, my treatment was a lumpectomy and radiation. My surgeon refused to give me a mastectomy as survival rates are equal between the two surgical options.
Re: Chemo or not?
I would go with my doctor's recommendation. Less than 1% benefit is not worth all the potential (and sometimes lifelong0 side effects chemo can have.
