This literature review presents the substantial evidence for the safety and efficacy of bioidentical hormone therapy, including estradiol, estriol, and progesterone, which shows that it presents lower risks for breast cancer and cardiovascular disease than synthetic or animal-derived hormones. Studies show that progestins have a number of negative effects on the cardiovascular system and an association with breast cancer risk that can be avoided by using bioidentical progesterone.
