I did some quick research and even Dr Andrew Weil cautions against ER positive patients taking milk thistle. Other reports mention experiments with female mice given very high doses of milk thistle extract (2700mg/kg) way above what a human would take and the effects on prevention of breast cancer and apoptosis of breast cancer cells were postitive not negative.

You can avoid (apparently) the estrogenic effects of milk thistle by purchasing milk thistle seed extract rather than the plant.This assumes the plant is really harmful. Go to Amazon and type in milk thistle seed extract. Ill do some more research as it keeps my retired mind active.
