Health studies about vitamin D and prostate cancer:

Serum Vitamin D Profile In Black African Men with Prostate Cancer at Tertiary Referral Facility in Sub-Saharan Africa (2014)

Conclusion: The vitamin D blood levels of 162 black African prostate cancer patients were analyzed. 88.9% of them were vitamin D-deficient.


Prostate Cancer Incidence in Australia Correlates Inversely with Solar Radiation (2011)

Conclusion: There is an increased rate of prostate cancer incidences in areas of Australia that receive less solar radiation compared to areas that receive more solar radiation.


Serum 25 OH Vitamin D Concentrations and Calcium Intake are Low in Patients with Prostate Cancer (2011)

Conclusion A study of 91 prostate cancer patients found that 78% had low vitamin D levels.


Exposure to Ultraviolet Radiation: Association with Susceptibility and Age at Presentation with Prostate Cancer (2011)

Conclusion: “A positive association between latitude and prostate cancer mortality has been interpreted to indicate that ultraviolet radiation (UVR) protects against development of this cancer.”


The Role of Vitamin D in Cancer Prevention (2006)

Conclusion: Sun exposure and vitamin D prevent colon, breast, prostate, and ovarian cancer


Phytoestrogens and Vitamin D Metabolism: A New Concept for the Prevention and Therapy of Colorectal, Prostate, and Mammary Carcinomas. (2004)

Conclusion: Optimization of vitamin D levels is important for tumor prevention


Vitamin D and Prostate Cancer Prevention and Treatment (2003)

Conclusion: Vitamin D causes prostate cancer cells to kill themselves (apoptosis), decreases their growth rate (proliferation), and hinders the cancer from spreading to other parts of the body (metastasis)


Sunlight and Mortality From Breast, Ovarian, Colon, Prostate, and Non-Melanoma Skin Cancer: A Composite Death Certificate Based Case-Control Study (2002)

Conclusion: Sun exposure lowers your risk of developing breast, ovarian, prostate, and colon cancer


An Estimate of Premature Cancer Mortality in the U.S. Due to Inadequate Doses of Solar Ultraviolet-B Radiation (2002)

Conclusion: Lack of midday sun exposure increases one’s risk for developing and dying from breast, colon, ovary, prostate, bladder, esophageal, kidney, lung, pancreatic, rectal, stomach, and uterine cancer.


Prostate Cancer Risk: Associations With Ultraviolet Radiation, Tyrosinase and Melanocortin-1 Receptor Genotypes (2001)

Conclusion: “Exposure to ultraviolet radiation may reduce prostate cancer risk”


Prostate Cancer Risk and Prediagnostic Serum 25-Hydroxyvitamin D Levels (Finland) (2000)

Conclusion: Men with lower vitamin D levels have an increased risk of developing prostate cancer


Human Prostate Cells Synthesize 1,25-Dihydroxyvitamin D3 From 25-Hydroxyvitamin D3 (1998)

Conclusion: Vitamin D3 “inhibits the invasiveness of human prostate cancer cells.”


Vitamin D and Prostate Cancer (1995)

Conclusion: Vitamin D inhibits the growth of prostate cancer cells


Geographic Patterns of Prostate Cancer Mortality. Evidence for a Protective Effect of Ultraviolet Radiation (1992)

Conclusion: There are lower prostate cancer mortality rates in the southern regions of America compared to the northern regions due to the south receiving stronger sunlight with more vitamin D-producing UVB radiation.
