Vitamin D May Significantly Decrease Breast Cancer Risk

Welcome to Weekly Health Update


A new research study suggests that breast cancer risk can be cut in half with adequate Vitamin D levels in the blood.



VITAMIN D MAY SIGNIFICANTLY DECREASE BREAST CANCER RISK

As I discuss in detail in my recent book, A Cancer Prevention Guide for the Human Race, there is considerable research evidence linking low Vitamin D levels in the blood with a higher risk of some types of cancer, and colorectal cancer in particular.As I have discussed previously in this column, there is also some research evidence available to suggest that low levels of Vitamin D may, similarly, be associated with an increased risk of breast cancer, as well as a possible increase in the risk of recurrence of prior breast cancers (although the results of still other studies have not supported these conclusions). Now, a new analysis of recent breast cancer prevention research studies suggests that higher levels of Vitamin D in the blood may indeedsignificantly decrease the risk of developing breast cancer.

Meta-analysis studies use powerful statistical formulas to combine the results of multiple smaller research studies into a single larger and more conclusive “meta-study.” This form of statistical analysis is especially useful for evaluating clinical research studies that have utilized different research methods to arrive at their final conclusions. A new meta-analysis of 11 previously published breast cancer risk research studies has just been published, and this new comprehensive meta-analysis appears in the current issue of the journal Anticancer Research.

Following meta-analysis of the results of 11 different breast cancer risk studies, this new study determined that high-normal levels of Vitamin D in the blood were associated with a significantly lower risk of developing breast cancer when compared to low Vitamin D levels. Indeed, in this meta-analysis, a Vitamin D level of 47 ng/ml in the blood was associated with a whopping50 percent reduction in breast cancer risk, when compared to women who had very low blood levels of this hormone-like vitamin.(While there is no uniform agreement on “normal” blood levels of Vitamin D, most experts recommend that Vitamin D levels be maintained in the 30 to 50 ng/ml range.)

While increased Vitamin D intake has been repeatedly linked with a lower risk of some cancers, as well as a decreased risk of heart disease, excessive Vitamin D levels in the blood can cause serious illnesses, including kidney failure, calcium deposits throughout the body, gastrointestinal ulcers, and other serious health problems. Therefore, prior to beginning Vitamin D supplementation (or, indeed, before starting any new supplement or medication), please consult with your personal physician first!
