    This web site is dedicated to vitamin D and cancer. This is because exciting new research indicates that vitamin D-whether produced in the skin as a result of exposure to ultraviolet radiation (from sunlight or sun lamps) or obtained from supplementation with cholecalciferol (vitamin D3)-may help cancer patients. However, the research is far from complete.

    Maintaining adequate levels of vitamin D during winter months requires a daily dose of 20 micrograms, four times the current recommended dose, says a new study. The study, led by Susan Sullivan from the University of Maine, has important implications for ongoing consultations on vitamin D recommendations, with the current level of five micrograms (200 International Units) seen by many as insufficient.

    "A study conducted by Cedric Garland and other prominent vitamin D researchers determined that women with vitamin D levels above 52 ng/ml have half the risk of developing breast cancer as those with 13 ng/ml! Garland (et al) estimates that 58,000 new cases of breast cancer in the U.S. could be prevented per year by raising vitamin D levels to 52 ng/ml. Imagine what the global impact could be! "

    ScienceDaily (Feb. 8, 2006) - Vitamin D can inhibit the spread of prostate cancer cells by limiting the activity of two specific enzymes, University of Rochester Medical Center scientists report. \n\nThe finding means that Vitamin D could provide beneficial treatment to prostate cancer patients with high levels of the enzymes, the scientists said.\n

    Vitamin D's days of obscurity seem pretty much over. Once just an afterthought to most people-relegated to the sides of milk cartons and the pages of medical texts-it's now on the cusp of becoming a full-fledged disease prevention star. Although vitamin D has long been known as an important factor in bone health, a quickly growing body of evidence now shows that it may also help lower the risk of cancer, heart disease, and even premature death.[1], [2] Not surprisingly, scientists and the public have started to take note, particularly of vitamin D's potential to protect against cancer

J Steroid Biochem Mol Biol. 2007 Mar;103(3-5):708-11. PMID: 17368188 CONCLUSIONS: Intake of 2000 IU/day of Vitamin D(3), and, when possible, very moderate exposure to sunlight, could raise serum 25(OH)D to 52 ng/ml, a level associated with reduction by 50% in incidence of breast cancer, according to observational studies.

    Sept. 12, 2006 -- Getting the recommended intake of vitamin D from diet, supplements, or even the sun may cut your risk of pancreatic cancer. The results of two large, long-term surveys show that adults who got 300 IU to 449 IU (international units) per day had a 43% lower risk of pancreatic cancer. The recommended intake of vitamin D for adults aged 51-70 is 400 IU per day.

    Vitamin D production in human skin occurs only when UV radiation exceeds a threshold. From simulations of UV irradiances, the VitD www page ( http://zardoz.nilu.no/~olaeng/fastrt/VitD.html) computes the daily duration of dermal vitamin D production at midday when UV radiation exceeds the required threshold. The daily duration depends on latitude, time, total ozone, clouds, aerosols, surface reflectivity and altitude all of which can be specified by the user

    Low doses of the active form of vitamin D and non-steroidal anti-inflammatory drugs act as a powerful combination to halt the growth of prostate cancer cells, say US scientists. Writing in Cancer Research, a team from Stanford University says it discovered that the amount of both activated vitamin D, or calcitriol, and NSAIDs could be reduced by half to one-tenth the dosage to thwart prostate cancer cell growth in cell lines and primary tissue culture

  • The researchers conclude: “This study shows a strong association between 25(OH)D levels and cause-specific mortality in patients with prostate cancer. The strength of the association indicates that prostate cancer patients can benefit from increasing the level of serum 25(OH)D if it is below 50 nmol/l.”

    Association between plasma 25-hydroxyvitamin D and breast cancer risk. Crew KD, Gammon MD, Steck SE, Hershman DL, Cremers S, Dworakowski E, Shane E, Terry MB, Desai M, Teitelbaum SL, Neugut AI, Santella RM. Cancer Prev Res (Phila Pa). 2009 Jun;2(6):598-604. Epub 2009 May 26. PMID: 19470790 In summary, these results add to a growing body of evidence that adequate vitamin D stores may prevent breast cancer development. Whereas circulating 25-OHD levels of >32 ng/mL are associated with normal bone mineral metabolism, our data suggest that the optimal level for breast cancer prevention is ≥40 ng/mL. Well-designed clinical trials are urgently needed to determine whether vitamin D supplementation is effective for breast cancer chemoprevention.

    ScienceDaily (Dec. 5, 2009) - A new study has found that the amount of vitamin D in patients being treated for diffuse large B-cell lymphoma was strongly associated with cancer progression and overall survival. The results will be presented at the annual meeting of the American Society of Hematology in New Orleans. Also, several recent reports have concluded that vitamin D deficiency is associated with poor outcomes in other cancers, including breast, colon and head and neck cancer. This is the first study to look at lymphoma outcome.

    What is VITAL? The VITamin D and OmegA-3 TriaL (VITAL) is a research study in 20,000 U.S. men and women investigating whether taking daily dietary supplements of VITamin D (about 2000 IU) or fish oil (about 1 gram of omega-3 fatty acids) reduces the risk of developing cancer, heart disease, and stroke in people who do not have a prior history of these illnesses. Recruitment for the study will begin in January 2010.
