For ONCOTYPE a pre menopausal woman needs a score equal to or less than 15 ( 18?) to find NO BENEFIT from chemotherapy.

Recommendations will be different for you regarding AI. Tamoxifen is also an oral AI that has been used pre-menopausal. Recently oncologists are sometimes using the Post menopausal AIs plus an injectable to shut down ovarian estrogen.

Your oncologist will review these options with you.

The waiting is so difficult. Wishing you the best on your journey. This is a safe place to get support. We have all gone through the devastation of a BC diagnosis but we each have unique variables and circumstances. We are not medical professionals but we share our journey. Your medical team will advise you on best steps forward. Hugs 🌸
