I guess I'll chime in here,

I read on another forum a woman who had taken PM with Grapeseed extract to increase estroil while decreasing the estradoil.

I guess for most women, when diagnosed with estrogen dominance, its most often estradiol that causes the bloating, weight gain, flashes etc. So taking these two together gave her healthy estrogen balance while effectively decreasing the dangerous, cancerous estradoil levels.

Estriol is the weakest estrogen and Estradiol is the strongest and most feminizing estrogen. While it's true that in women, higher does of Estradiol strongly acts on breast cancer cells, I'm not sure the same effect is seen in men. In any event, men who want to feminize want the Estradiol since it's the most feminizing estrogen.

I honestly can't say anything about Grapeseed oil from the point of view of feminization but if it converts Estradiol to Estriol then yes it ought to limit the growth of breast cancer cells in women all else being equal.
