Does Milk Thistle SEED extract have estrogenic effects?

Calling all herbal experts...

Recently I have received indication that I have estrogen overload (uterine fibroids, suspicous areas in breast). I'm reading a lot of conflicting info on MTS ---

Milk thistle extract DOES mimic estrogen - but the extract from the seeds does NOT?

One MD even commits that plant compounds - phytoestrogens have POSITIVE estrogenic effects. I know there is some misunderstanding about estrogen receptors and what blocks and what binds although I'm not sure I actually understand it. Dr Weil suggests that the MTS does not have the same estrogenic effect as the plant extract.

I had a breast thermography done by a specialist who has followed up studies on soy estrogen link to breast cancer and she developed studies showing flax seed effects on estrogen and breast cancer. She is suggesting I go off MTS.

But is this simply a confusion over forms of milk thistle - and what is extracted from the seed?

Thoughts?

I would love to know this answer as well.
