Some doctors in Canada are warning women that they are courting risks they may not even be aware of when they turn to bio-identical hormone replacement therapy to treat the symptoms of menopause.

The therapy, also known as BHRT, uses hormones derived from plants such as yam and soy. BHRT has been growing in popularity because of fears over risks from traditional hormone replacements, derived from the urine of pregnant horses.

The use of standard hormone therapy for women suffering hot flashes, mood swings and other symptoms of menopause plunged after a landmark study in 2002 linked it with an increased risk of breast cancer.
