Ill do some research on the estrogenic effects of Milk thistle and try to determine how clinically significant these effects are. If you are on estrogenic blocking drugs like Tamoxifen, Evista or Faslodex these possible effects are likely to be minimized. Cant say for sure.

Aromatase Inhibitors prevent Estrogen formation but don't block estrogen action so AIs probably wouldnt be protective. Its all kind of up in the air.
