Many women are scared off by connections that have been made between hormones and cancer. It is important to understand that these studies link synthetic hormones to breast cancer, ovarian cancer and uterine cancer. There have been no studies that look only at bioidentical hormones and cancer . This is because the studies are expensive and the manufacturers of synthetic hormones provide the synthetics for free. Bioidentical hormones are created by a compound pharmacy to match an individual’s body chemistry, so the hormones cannot be used for studies unless they have been matched to each of the participants. It is also important to note that a woman’s natural estrogen has essentially no connection to endometrial cancer and bioidentical hormones, unlike synthetic hormones, are identical to a woman’s natural estrogen.

Synthetic estrogen has been found to increase a woman’s chances of developing these various cancers. Some of those risks were dimmed with the addition of synthetic progesterone, but still it was balancing a risky synthetic hormone with another synthetic hormone. High levels of estrogen are linked to breast cancer. These high levels can occur when your progesterone is too low, not uncommon in menopause, and when synthetic estrogen replacement therapy is being used. Bioidentical hormones and breast cancer have been found to have no negative correlation; in fact, bioidentical hormones reduce the risk of breast cancer by correcting the menopause hormone imbalance.

Bioidentical hormones risks are by no means equal or even similar to synthetic hormones.
