I certainly was not the same as you and didn’t even have all the tests you did since it was a time ago and they weren’t thought of yet.
That being said I did look at what I was eating. I didn’t make crazy unsustainable changes. I did start buying dairy that was hormone free, grass fed hormone free beef on the rare meat meal. I also eliminated commercial corn, we don’t eat a lot of processed stuff, but you would be surprised where you find it.
I didn’t give up my coffee, or my tea, even the fancy stuff on occasion. I did not give up pasta, or cake. 😂😂
Do you have planned changes that won’t cost you a happy quality of life?

I used to think we should avoid soy with cancers that are responsive to estrogen, but have since that is not true. I am not sure what other foods are estrogenic. But the Tamoxifen addresses the estrogen receptors so my understanding- check with your doc- is that in some ways it doesn't matter what level of estrogen is floating around in your body, the receptors are being shut off by the med and the estrogen is not getting to any potential cancer cells. I hope your doc can clarify this.

Aromatase inhibitors used after menopause, on the other hand, deal with the amount of estrogen in the body, not the receptors, so estrogenic foods would seem to be more of an issue there, but I am not aware of any so maybe someone else can enlighten us.
