Topical Progesterone, Not Synthetic Progestins or Oral Progesterone, Should Be Considered as a Companion for Estradiol Replacement Therapy

Posted by Ben White on

By Dr.David Zava, ZRT Laboratory In 2002 several large-scale clinical studies were published on the risks of breast cancer in postmenopausal women using conventional FDA-approved hormone therapy. These were the Women’s Health Initiative (WHI) and Million Women’s studies of women using FDA-approved estrogens and progestogens in the United States and Great Britain, respectively [1,2]. Both studies came to the same conclusion – that estrogen therapy, mostly in the form of oral conjugated equine estrogens, by itself did not significantly increase the risk of breast cancer and, to the surprise of many, was associated with a lower risk. However, when estrogen was...

Genetic Sequence Variations and Breast Cancer Risk

Posted by Ben White on

  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...

What Exactly Are We Talking About Breast Cancer

Posted by Ben White on

Having breasts, or just being a woman, is indeed the biggest risk factor, since the disease is 100 times more common in women than in men. But given the controversies that continue to rage about the benefits of screening (for example, a mammogram may not pick up the most invasive and deadly types of breast cancer) it seems appropriate to step back and look at what breast cancer really is, what it is not, and who is at the most risk.  What Breast Cancer Is Not Breast cancer is not the leading cause of death in women, or even the...

Breast Cancer: Prevention is the Cure

Posted by Ben White on

October is Breast Cancer Awareness month, with a flurry of activity directed towards “Race for the Cure,” pink ribbons on posters and products, and people on street corners with butterfly nets to accept donations to defeat breast cancer. Yet with all this activity over the past 30 years we are no closer to any cure, and breast cancer rates have escalated. According to the National Cancer Institute, incidences of breast cancer in the US have risen during the past thirty years from 1 in 30, to 1 in 8 women life time risk (1). Agencies that track these statistics are concerned that...

Natural Progesterone Can Help Treat Breast Cancer- New Research Shows (Part 2)

Posted by Ben White on

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...
