Oncotype dx and Mammaprint discordance early stage breast cancer

I had grade 3, LVI but low Oncotype of 8 with risk halved by Femara. (Thirty percent of grade 3's have low Oncotype.) Breast Cancer Index at year 5 showed high risk at 5.5% (just over the line and not too different from Oncotype), and low effectiveness of meds. The Prosigna had me at high risk at 10%, 5 years out. You can call each test company to discuss. It's tough that they don't agree.

Thank you! I did contact Mammaprint who explained that they review other factors and that their test should be trusted. I will contact Oncotype Dx and am currently scheduled for BCI test. Thank you again.
