Vitamin D- Breaking News in Cancer Highlights (Dr. Mercola):
According to Dr. Garland:
It is projected that raising the minimum year-around serum 25(OH)D [vitamin D] level to 40-60 ng/ml would prevent approximately 58,000 new cases of breast cancer and 49,000 new cases of colorectal cancer each year, and three quarters of deaths from these diseases, in the US and Canada.”
And
“The first event in cancer is loss of communication among cells due to, among other things, low vitamin D and calcium levels. In this new model, we propose that this loss may play a key role in cancer by disrupting the communication between cells that is essential to healthy cell turnover, allowing more aggressive cancer cells to take over.”
This is different from the genetic theory…
Just a naturopathic side note: Remember that your liver is responsible for conversion of vitamin D, so don’t just supplement with high doses of Vitamin D without having your practitioner run some basic liver tests or check symptomology. Also request a vitamin D level, it is a fat soluble vitamin and can become toxic in high doses.
