flaxseed lignans inhibit estradiol induced growth, angiogenesis, and VEGF secretion

[TSund]

Has there ever been any proof that phytoestrogens ARE indeed bad for ER+?

I understand the theory, however I've also heard the hypotheses that phytoestrogens will actually help as while mildly estrogenic, they take the place on the receptors of much more dangerous forms of estrogen and lower the bodie's instinct to make more estrogen, which may be of the "bad" or "strong" variety.

I don't know which side has definitive evidence...

There was a trial underway in Australia but I have not seen any more. I will try and find out.

I use flax because its positive effects on Her2 are almost undisputable. I use it about 2X per week (the ground seed which would be more concerning if ER+ of which I am 50%). I use the oil too which I do not get the high lignan. That is not concerning. I use soy the way I used to before bc, if it came in some Chinese food we all ordered and shared (usually one meal or the soup has it). I was never a biggie on soy - maybe that was bad as I feel these foods are beneficial as a preventative to get bc. Once had, who knows but I believe flax is good so I will purposefully have it about 2X per week.
