Do progesterone supplements cause cancer?

What kind of cancer does progesterone cause?

Studies have also shown that a woman’s risk of breast cancer is related to the estrogen and progesterone made by her ovaries (known as endogenous estrogen and progesterone). Being exposed for a long time and/or to high levels of these hormones has been linked to an increased risk of breast cancer.

Can progesterone supplements cause breast cancer?

The short answer is NO! However, we have no randomized controlled trial data (the most important kind of scientific study) documenting that. (Note that some short, exploratory studies are now, finally, starting to be done2). There has been no risk of breast cancer ever documented from taking progesterone alone1.
