AI inhibitors inhibit the bodies ability to produce estrogen. People who have had estrogen positive cancers are those for whom an AI inhibitor can help prevent a recurrence of the hormone positive cancer. Certainly there are people who do not react well to medication’s. There are also people who have little or no issues with medication’s.

It is possible that you'll have no side effects on aromatase inhibitors. People react differently, and often on a chat the folks with problems post, which makes sense. But that is not the whole view. I've been on letrozole for three years with zero side effects and my bone density is normal. Certainly bad side effects can be intolerable, but don't assume you'll have these side effects. I told my oncologist initially I'd take it and go off it if the side effects were unbearable. And it has been fine. Actually better than fine, as I've outlived my original prognosis.

I made the decision not to take them. Had surgery and radiation and just had my first set of scans and testing eight months out and all clear. Like you, I am very low risk and AIs decreased that risk only slightly so not worth it to me. All of us have different perspectives and experiences and certainly no judgment here at all. Good luck to you, quality of life at my age, won out in making my decision
