It now seems clear that your oncologist was probably not referring to Breast Cancer Index results, which are an absolute yes or no.

My oncologist also cited "small benefit," but not based on the BCI.

BCI's don't give that information. I found the test frustrating for that reason and would ask the company about retesting if they are now quantifying benefit or no benefit. 40% benefit is different from 5% benefit, for instance.

I don't need to talk to my oncologist. I am all set. Your post just confused me and now I understand that your MD was not referring to the results of the BCI.

Maybe you could dig out your results. It should say benefit or no benefit, not small or large benefit 🙂
