Breast Cancer Index Test

Kessa619 · January 2021

Hello! I am approaching 5 years of ovarian suppression + AI. At my request, my oncologist ordered the Breast Cancer Index test. It showed a 1.9% risk of late recurrence and no benefit to continued use of AI. My question is this: should I trust the test? I am eager to stop the Lupron/Arimidex, but also terrified. How have others’ doctors viewed the test?

Thank you so much for any responses!

kessa - my MO also recommended the BCI test at the 5 year point. Unfortunately I fell into the high risk for recurrence, low benefit from continuing on anti-hormonals, which only one in ten who test do. My MO asked me to remain on Letrozole if I could deal with side effects, which I did for another two and a half years. At that point I needed some jaw/tooth surgery and my maxillofacial surgeon wanted me off any meds that could affect bone so I stopped at that point with the blessing of my MO. He is a believer in the test, and does use it. Here are comments from other members, and if you use the search function and put BCI or Breast Cancer Index in there are some other scattered posts on other threads
