Re: Soy and ER/Her2 pos: not yet

Who knows whether it's an issue in acquiring cancer. But in light of the recent suggestion that it's now ok for ER+ breast cancer, figured this wrinkle regarding the 15% or so of BC that's Her2/ER pos is worth noting. It's too bad. In Her2 negative, soy seems to make estrogen receptors more susceptible to endocrine therapy. Damn crosstalk...
