I ve recently had breast cancer surgery. My surgeon is suggesting hormone therapy for follow up treatment. My cancer was found in the early stages, no lymph nodes were involved. I am 77 years old, and her feeling is that aromatase therapy will be what is prescribed for me for follow-up. I had oncatype DX genetic testing done and everything was negative. My recurrence score result is 20. In reading my results from the report do I see the score of 20 as a high low risk, if so, do we have a way of figuring what my risk of recurrence would be if I chose not to do anything?
