Hi @Pommy8
I did Oncotype. It was expensive, but I needed to be told about the necessity of my chemotherapy with the scientific test results.
The test takes 21 business days. I went back to work during this waiting time. That was a great time to give me a break from my breast cancer stress and focus on something different. I loved spending a few weeks of normalised life.
I also think the experience going through treatment, especially AC, would be different if I did not see the test results. I would have had doubts about if I needed chemotherapy. Even though my oncologist is very experienced, he is only a human. No one is perfect. All the doctors have insurance.
Please think about what is best for you. We are all different.
Wishing you a best
