Deficiency of Vitamin D Leads to Cancer

Vitamin D deficiency is related to lack of exposure to sunlight. It has been found that there is a correlation between lack of vitamin D and prostate cancer. A basic finding of the following study is that there is an inverse correlation between ultraviolet radiation and mortality from prostate cancer. What this means is that the less sunlight you receive the greater your chances of dying from prostate cancer. Abstracts are usually couched in arcane jargon. But this time researchers stated their findings in unusually clear language:
Prostate cancer is a major cause of cancer death among males, yet little is known about its etiology. We hypothesize that Vitamin (Hormone) D deficiency may underlie the major risks for prostate cancer, including age, Black race, and northern latitudes. These factors all are associated with decreased synthesis of Vitamin D. Mortality rates from prostate cancer in the U.S. are inversely correlated with ultraviolet radiation, the principal source of Vitamin D. This hypothesis is consistent with known antitumor properties of Vitamin D, and may suggest new avenues for research in prostate cancer.
The meaning of this finding is clear. In order to cut the risk of prostate cancer, it is imperative to obtain sufficient sunshine and/or vitamin D.
