Brief Summary

According to the Canadian Cancer Society, 1 in 9 Canadian women will develop breast cancer in her lifetime and 1 in 30 will die. The single greatest risk factor of breast cancer is poor estrogen metabolism. EstroSense®/MD is a natural health product that promotes and supports healthy estrogen metabolism. It may increase the ratio of "good estrogen" to "bad estrogen" and potentially reducing the risk of breast cancer. For this proposed study, the investigators will be examining the effect of EstroSense®/MD compared to placebo, on estrogen metabolism in 120 women.
