I know that using high doses of phytoestrogens is quite common, such as missmadscientist's soy and flax method, which is quite popular on this forum. However, the more that I look into it, there are a few things that don't make sense to me.

Phytoestrogens mimic real estrogen by binding into the same receptors that estrogen would. This is why it is believed to reduce the risk of breast cancer, by reducing the amount of estrogen that bind to the receptors. By this logic, it should hinder breast growth, not increase it. I'm not sure why breast growth from phytoestrogens would have any less of a cancer risk than using natural estrogenic methods like PM or BO etc. It seems like whatever method you use, breast growth = increased cancer risk. What is the cancer risk of NBE methods, realistically?

On the same topic, why is it that natural breast growth from puberty or pregnancy doesn't have a risk of breast cancer (at least that I know of), but using hormonal methods have the risk? As someone with a family history of cancer, this is a big concern of mine that's looming on me as I go through my NBE journey. I'd love to know what you guys think.
