Dr. Weeks’ Comment: When the pathologist determines your estrogen receptors are positive in cancer, then by all means stop taking estrogen agents and increase Calm Cream (transdermal bioidentical progesterone) as well as agents to lower your estrogen since estrogen is well- understood to be carcinogenic. But when your progesterone receptors (PR) are determined to be positive, what then? What does the science instruct us to do? Well, since progesterone is ANTI-CANCER the logical conclusion is that when the progesterone receptors are positive (receptive and functional and ready to serve) then give progesterone and allow progesterone to do what it does best: counter-balance the cancer causing effect of estrogen. Progestins are another story – being as they are synthetic near-miss progesterone mimickers. So by all means avoid progestins (an ingredient in the lethal drug PremPro which was recalled). Progestins cause cancer. Does your oncologist understand that progestins are NOT actually synthetic progesterone but rather synthetic near-miss knock-offs of progesterone? If not, either share the following research with him or her or simply find a more informed doctor!
John Lee MD (who published what he learned from Ray Peat ND) is quite persuasive.
