John Lee, MD, along with David Zava, PhD, in Dr. Lee's final book, bring us up to date with the latest information on progesterone and its role in breast cancer.

Published by Dr. Lee's estate, this compilation is a comprehensive, easy-to-follow handbook based upon Dr. Lee's lifetime works.

The third edition of The Estrogen Alternative includes many studies showing how progesterone opposes estrogen's stimulatory effect on cell growth, as found in endometriosis, fibroids and cancers of the breast, uterus and ovaries.

The Estrogen Alternative translated into Spanish.
