Are you reluctant to try an AI or did you try one and have side effects? Many of us had few side effects (though bone loss needs to be monitored).

What do you mean by "cancer free"? Five years, ten, twenty?

Even if someone answers your question by saying yes, they remained cancer free without meds, that would not tell much about your own personal risk.

Have you had an Oncotype Dx test? That should tell you your risk of recurrence with and without meds. Everyone's score and overall profile is different.

If your case would seem to suggest AI's reduce risk, I hope you will try one!
