Here, in one eloquently worded, organized and argued paper was the same basic argument that Dr. Lee, Dr. Zava and myself made our 2002 book, What Your Doctor May Not Tell You about Breast Cancer about why
progesterone is protective against breast cancer and progestins cause it.
Even one full - term pregnancy
is remarkably
protective against breast cancer, probably because
progesterone and other pregnancy hormones cause permanent changes in
breast tissue that
are protective, and because
progesterone levels
are very high in the last few weeks of a full - term pregnancy.
