Vitamin D deficiency common in cancer patients study is needed to continue to understand the relationship between vitamin D and cancer.". The vitamin D–cancer prevention hypothesis has been evaluated through several . {CIs}]) for the association between vitamin D deficiency and Stage II and III cancers . Many studies examining the relation between cancer incidence and. Vitamin D deficiency is too common today affecting an estimated 1 billion people worldwide or 90 percent of the world's population.

But just as vitamin D can promote good health, a lack of it may lead to health issues. If you fit this description, consider voicing your concerns to your primary care provider or a registered dietitian. These professionals can work with you to modify your diet or lifestyle and correct the problem. Depending on where you live, your sun exposure during the wintertime may be minimal, leading to lower levels of vitamin D. Dementia involves a decline in thinking, behavior, and memory that negatively affects daily life.

Compared with people with normal vitamin D levels, those with low levels of the vitamin had a 53 percent increased risk of developing all-cause dementia, while those who were severely deficient had a percent increased risk, researchers observed. Considering the devastating toll that dementia can have on patients and their families alike, those findings may seem alarming.

Nonetheless, they theorized that the sunshine vitamin might help clear plaques in the brain that are linked to dementia.

Vitamin D and Cancer: An Unclear Relationship

Calcitriol is active Vitamin D which responds more like a hormone than a vitamin. Scientists argue that calcitriol is in fact the most powerful hormone in the human body responsible for stimulating more than 1, genes or about 5 percent of the human genome. Ideally, individuals should seek to receive 10, to 20, IU of Vitamin D3 from sun exposure when 60 percent of the body is exposed. Protect your skin with antioxidants from moisturizing with coconut oil, green tea extract and aloe vera before and after sun exposure.

Cancer Tutor is here for you. The other study looked at vitamin D3 supplementation for colorectal cancer patients. Robert Heaney outlined how vitamin D clinical trials could be conducted.

The key points include the following: Start with an understanding of the 25 OH D concentration—health outcome relationship. Measure 25 OH D concentration of prospective participants and try to enroll those with concentrations near the low end of the relationship.

Give vitamin D3 doses high enough to raise 25 OH D concentrations to the upper part of the relationship. Measure 25 OH D concentration again during the trial to determine the success of the dosing and assess compliance Guidelines for designing vitamin D trials more likely to find beneficial effects were outlined in two recent papers 5 It was suggested that all trial outcomes be related to 25 OH D concentrations, measured several times during the trial, with adjustments in dosing to produce desired achieved concentrations Comparing cancer survival between black and white Americans.

Another way to assess vitamin D's role in cancer is to examine the disparity in cancer survival rates between black and white Americans. According to a review of the journal literature, disparities are evident for 13 cancers after consideration of socioeconomic status, stage at diagnosis, and treatment in most cases: Of course, other lifestyle factors could also be involved. One concern is that black Americans have a different biologically available 25 OH D concentration. That effect was believed to be a result of a different relation between total and free 25 OH D due to a different effect of the vitamin D—binding protein But a recent study dispelled that concern by showing nearly identical odds ratios for free and total 25 OH D concentrations for colorectal cancer incidence for black Americans Table V presents findings of ecological and observational studies regarding cancer incidence, survival, and mortality rates with respect to indices of solar UVB or 25 OH D concentration, as well as results regarding disparities in cancer-specific survival rates between black and white Americans.

The ecological study findings are taken from the review in 2. The occupational exposure results are primarily from an analysis of SIRs by occupation The observational results for 25 OH D concentrations are generally the latest meta-analysis. If no meta-analysis has been published, the most recent paper is used. The results for African Americans are from 11 along with results from later papers.

The cancers are grouped into epithelial or hematopoietic hematological categories and arranged in descending order according to estimated incidences in That order is used because the likelihood of finding effects of UVB or vitamin D is expected to increase with the annual number of cases.

In a new window Table V. Summary table of significant inverse relationships regarding UVB dose, 25 OH D concentration, on cancer incidence, survival, mortality rate or survival disparities for African Americans compared to white Americans. In addition, seven of those 17 also have studies reporting significantly poorer survival rates for black Americans than white Americans. The findings are less robust for hematological cancers, with little support for protective effects against cancer incidence.
