@kware75 and @auntieoakley the Oncotype is used for 1-3 nodes. Micro mets in one node isn't too different from lymphovascular invasion, which I had, and I did not have chemo thanks to the Oncotype.

If your doctor won't order one, I think a second opinion would be helpful.

How does your doctor "know" the Oncotype will be low? There is no way to tell in advance. Thirty percent of grade 3's have low scores and grade 1's may have a high score. Of course, most results are as expected but you cannot predict.

I know women who had a positive node and did not do chemo. It all depends. If you are making the choice, I have you have correct information to base it on.

I have never heard that if it makes it to the lymph nodes it has traveled elsewhere. I have heard that shows the cells "want to go somewhere" and have the capacity to travel, but not that they have.

If your cancer is highly responsive to estrogen, hormonal meds can help a lot without chemo. The Oncotype is really important to guide your treatment.
