How Carole’s Breast Cancer Experience Sparked the Beginning of GrassrootsHealth, 15 Years Ago

Carole Baggerly was diagnosed with breast cancer in 2005. As she describes it, the cancer was bad enough, but then, she had the treatment for cancer. She had a mastectomy, chemotherapy (which permanently damaged some of her body), and radiation (until she bled), and all of that led her to an intense desire to find a better way to address breast cancer. Through her research and the research of the scientists she met in the months that followed, she found a way to address it – through prevention.

Carole was invited to attend a two day seminar in May of 2007, sponsored by the National Cancer Institute, with researchers from all over the world presenting what they knew about vitamin D and cancer. So much was already known about vitamin D and cancer! Yet what were they going to do with the information? What was the researchers’ response to how they were going to get the message out? Carole immediately realized that, while these researchers had spectacular scientific knowledge about the role of vitamin D in cancer prevention, their message would fail to get out without a dedicated “sales” team!

It was from this realization that GrassrootsHealth and D*action were born – to help get the message out of the importance of vitamin D and achieving a blood level of 40-60 ng/ml (100-150 nmol/L), to give access to many individuals who did not have a way to test their vitamin D level at the time, and to further define the health outcomes related to a level within the 40-60 ng/ml range.
