I'm in pretty much the same boat you are: small tumor, no positive (or at least no "reallly" positive) lymph nodes. I had one very conservative oncologist who recommended chemo, and another who thought I could skip it. I had the Oncotype DX test in January as a sort of 3rd opinion. My recurrence rate came back at about 12%, which was low enough for me to be comfortable skipping chemo and taking Arimidex. I am still arguing with my insurance company, Aetna, over payment for the test. They have a clinical bulletin in which they list it as "experimental", but that bulletin predates the New England Journal of Medicine article in Dec. 2004 that validated the test. I'm keeping my fingers crossed that Aetna pays, but even if they don't, I'm happy I had the test done.
