Exactly. The BCI did not say small benefit. Your doctor did. The BCI does not give the amount of benefit, only whether there is any.

My doc said the same (based on low Oncotype) but if the BCI had indicated benefit, I would have continued my meds for 2-5 years. I have read that 7 years may be as good as 10.

I talked with the BCI company about discrepancy between Oncotype and BCI. They said they measure different things. One measures the number of cars, as an analogy, and the other measure the speed of the cars.

Not sure many MD's know that much about the BCI . At least based on what my docs told me. One of them starting using it after I requested it: she did not know about it. I believe it has made its way into the NCCN guidelines finally.
