Vitamin D and Death Due to Colorectal Cancer

Based upon recent high high quality clinical investigation, only Vitamin D, amongst all vitamins, appears to have potentially significant cancer prevention effects. However, as with all areas of clinical and laboratory study, 1 can obtain contradictory analysis outcomes for Vitamin D, as nicely.

An innovative prospective clinical study study is now reporting its outcomes, which appear to link Vitamin D deficiency to colorectal cancer death rates. As with previous research studies, the findings of this study strongly suggest that Vitamin D deficiency may be linked with a greater risk of death due to colorectal cancer. The findings of this clinical research study appear in the current concern of the journal Cancer.

An intriguing and special aspect of this specific clinical research study was its evaluation of the possible impact of Vitamin D deficiency on the properly-recognized increased risk of death due to colorectal cancer that has been observed in African-Americans when compared to Caucasian patients. As our bodies make active Vitamin D from exposure of our skin to sunlight, and as men and women with darkly pigmented skin are alot more prone to developing Vitamin D deficiency, when compared to lightly-pigmented many people, the authors of this study sought to assess the possible colorectal cancer risk impact of Vitamin D deficiency on patient volunteers with darkly pigmented skin.

In this huge public wellness study, the Third National Health and Nutrition Examination Survey (NHANES III), which was conducted among 1988 and 1994, blood levels of Vitamin D had been measured in study volunteers. Patients with a Vitamin D level of much less than 20 ng/dL were deemed to be deficient in Vitamin D.

As prior public wellness studies have also shown, the results of this study indicated that African-Americans are twice as likely to die of colorectal cancer when compared to Caucasians. When blood levels of Vitamin D had been deemed, specifically, the increased risk of dying from colorectal cancerobserved in African-American patients decreased by 40 percent among those African-Americans who had regular levels of Vitamin D in their blood. (These outcomes, for that reason, suggest that at least 40 percent of the increased risk of dying from colorectal cancer in African-American persons is most likely to be triggered by Vitamin D deficiency.) When patients of all races had been regarded as in terms of Vitamin D deficiency as a risk factor for death due to colorectal cancer, patient volunteers with a blood level of Vitamin D less than 20 ng/dL were even more than twice as likely (i.e., a 211 percent boost in risk)to die of colorectal cancerduring the course of this prospective investigation study, when compared with patients who had typical Vitamin D levels.

In summary, this sizeable prospectively conducted public well being study identified, as have previous studies, a substantial association between Vitamin D deficiency and the risk of dying from colorectal cancer. (Prior Vitamin D studies have also identified a 25 to 40 percent reduction in the incidence of colorectal cancer, and death due to colorectal cancer, in study volunteers with blood Vitamin D levels in the 30 to 40 ng/dL range.) When not all clinical investigation studies have shown this level of colorectal cancer risk reduction associated with normal blood levels of Vitamin D, this specific study joins a growing list of clinical studies that appear to show a significant reduction in colorectal cancer risk linked with adequate levels of Vitamin D in the blood.

As excessive Vitamin D intake can cause substantial wellness troubles (specifically in patients with kidney disease and parathyroid gland illness), you should certainly check with your doctor prior to taking into consideration the use of Vitamin D supplements.
