Check out info on Estrogen Dominance, the underlying condition that may contribute to PCOS. Dr John Lee addresses this in his book,
What Your Doctor May Not Tell You About Pre-menopause. While your daughter is clearly NOT in pre-menopause, the info on ED is very illuminating (and can be caused by the presence of xenoestrogenic compounds in the environment around us). You can probably find the book in your local library.
Good luck!
