Q. do-bioidentical-hormones-cause-breast-cancer?

No, bioidentical hormones do not cause cancer. This false impression began in 1991 when the very controversial Women’s Health Initiative (WHI) was halted due to increased incidence of chronic disease among subjects. This study used the synthetic hormone, Prempro, and subjects of the study were an average age of 63 years. Meta-analyses following this study have shown that most of the subjects had pre-existing conditions that led to the development of disease during the study and that hormones actually reduce the risk of cancer and other chronic diseases in women.

In fact, more than 15 major medical organizations now endorse hormone therapy as a safe and effective treatment plan for many adverse health conditions (2013). And, according to a 2015 survey conducted by the North American Menopause Society, more than 60 percent of clinicians prescribe or support the use of bioidentical hormones.
