Does anyone know what Estradiol should be after using an AI?

Is there any evidence demonstrating lowering estrogen levels is actually beneficial for recurrence or survival? I would like to see the evidence.

you don't need to have zero estrogens (estradiol, estrone, estriol) estrogen dominance only means that your estrogen is out of balance with your progesterone, you estrogens can be high, as long as your progesterone is higher, the ratio should be approx 300 to 1.

For what it's worth, I was listening to a couple of womens health docs discussing hormones on Dr. Radio (Sirius) recently, and they said that any estrogen test you have only shows your estrogen at that particular time -- that our estrogen levels fluctuate a lot throughout the day, so 20 minutes later, the reading could be totally different.  Doesn't that make testing somewhat pointless?   

Interesting, they also both wholeheartedly endorsed estrogen rings for low estrogen dryness, including for women who have had bc.  They said they're perfectly safe for us.  The host docs on this station are out of NYU Medical Center, and sound pretty top notch to me.  After listening to them, I wondered if the reason most oncs won't RX an estrogen ring might have more to do with liability fears than any real risk.   Deanna

Luna!  The progesterone should be he highest, so the ratio should be 300 to 1 progesterone to the estrogens, so if your estradiol/estrone etc is high, as long as your progesterone levels are higher it should be ok.  For instance, my latest saliva tests showed that my estradiol was still pretty high, however my progesterone had gone from almost zero to almost 3 times the level of the estradiol, so the doc was ok with the higher estrogen. Its also so flippin complicated in my opinion.  I still think that the more important indicator is the 2:16 ratio, I prefer to look at that.
