Blog — Breast Cancer Risk

By Sherry LaBeck, ND. ZRT Laboratory. It is highly likely that women aged 60 to 90 have vivid memories of the astonishing healthcare news from 2002 when the Women's Health Initiative (WHI), a comprehensive long-term national health study, was abruptly terminated earlier than expected. The initial trial results sent shockwaves through the medical community and had a profound impact on the lives of numerous women. Furthermore, this news fundamentally transformed the perception of routine menopausal hormone replacement prescriptions for years to follow. The WHI was launched in 1991 as a 15-year trial, one of the largest women’s health studies in the...

  Single nucleotide variations (SNVs – formerly single nucleotide polymorphisms, SNPs) are the most common genetic variations in individuals. Research shows that some SNVs can help predict an individual’s risk of developing certain diseases, such as breast cancer. Although future studies are necessary to further characterize the involvement of SNVs in the etiology of breast cancer, this blog will review up to date literature of what science has discovered so far regarding SNVs within the steroid metabolism pathway and their relationship to breast cancer. First things first – a crash course in genetics. To make an enzyme, just as for...

A Recipe for Beating (and Preventing) Breast Cancer The latest research on natural progesterone and breast cancer clearly indicates how important it is for women to maintain healthy, normal levels of progesterone that are in proper balance with estrogen. Doing so could not only increase many womens’ chances of recovering from breast cancer – as the latest research indicates – but could also help them to avoid getting breast cancer in the first place. As Dr. John Lee and Dr. David Zava point out in their book, hormonal imbalances have reached epidemic proportions in most developed countries over the last...

 A large team of scientists working on multiple continents published a research study that came to startling conclusions about breast cancer and natural progesterone. The team determined that unlike synthetic progestins, which increase breast cancer risks, natural progesterone has the potential to slow the growth of many breast cancer tumors or even shrink them. While this finding is stunning, it is not new. It is one of several conclusions about progesterone that Dr. John R. Lee, M.D. and Dr. David Zava, Ph.D. made more than a decade ago when they co-wrote the book, What Your Doctor May Not Tell You...
