I would be frustrated with that answer too. I just had the BCI test and I have been on Anastrozole for a little more than 4 years. I was stage 1a. Well the BCI test said I would benefit from an additional 5 years of taking the AI, however, I have already had two other oncologists tell me that don't even order the BCI for stage 1 because they said BCI does not differentiate between Stage 1 and 2 and his view is there is a difference that should be considered. Another oncologist said the risk for continuing in his view is not worth it given my current rate of recurrence would change to .8 of I extended for another 5 years and like 1.3 if I don't. So I have just learned over the last four years that some of the decisions made are based on what the Drs patient experience overall has been and the Drs best advice.
