There are two numbers you receive from the OncotypeDX. The "Recurrence Score Result (RS) and the "Distant Recurrence Risk at 9 Years." So I'm guessing that, in your case, the former is 13 and the latter is 4%? [My numbers were 9 and 3, respectively. The risk number is derived from the RS by some OncotypeDX algorithm but is not a linear, direct calculation from what they told me.]

That's good news and I hope it provides a bit of comfort. You might decide to 'throw everything at" the remaining cancer risk, or not, but take comfort that that cancer doesn't put you squarely in the country-wide risk with people who might have comorbities or negative lifestyle factors that you know don't apply to you.

I found the OncotypeDX test very helpful. For one thing, even if I took anti-hormone therapy drugs, I'd still have the remaining 3% risk in theory. I decided that the additional 2 percentage points of "no drugs and 5%" was my path. And if the cancer does recur, I'll know it had a 3% chance even if I had taken the anastrozole. Cancer is like a lot of situations in life where there are no perfect decisions except, maybe, in hindsight.
