Recent medical research has concluded that patients who get their cancer surgery cure in the warmer months - and as a result an intake of frequent doses of vitamin D - have a much better chance of surviving some forms of cancer. The rate of success in the struggle to fight cancer is higher than those patients who have their surgery in the winter and therefore they take smaller doses of vitamin D from sunlight.
In 2005 a group of scientists and researchers from the United States published a study released in the magazine "American Journal of Public Health", that seems to show and prove a curative inter-dependence between the intake of vitamin D and cancer prevention. So, cancer and vitamin D are interconnected. Based on the findings from their review of sixty three recent studies, the scientists maintained the fact that taking 25 micrograms - or 1,000 international units (IU) - of those vitamin every day could reduce a person's risk of cancer in colon cancer by 50%, and in ovarian and breast cancer by 30%. However, cancer specialists say that subsequent investigations should prove specific proof concerning prevention of cancer by vitamin D.
Proof of vitamin D's cancer protective effect is insuperable. For more than fifty years, medical literature documentation has stated that constant sun exposure refers with essential reduces in rates of death from definite cancers and a reduction in overall death cancer rates. Recent studies and investigations suggest this is an accidental relationship which acts through metabolic pathways of vitamin D in the human body. For example, some proofs indicate the fact that a colon, colon and prostate cancer belt in the USA that is located in northern latitudes and has more cloud coverage than other USA regions all year long. Levels of those cancers are from 2 to 3 times stronger than in regions with lower cloud coverage.
It is a very interesting fact about cancer and vitamin D that people with dark skin require more volume of sunlight to produce protection of cancer - vitamin D. The skin thickness layer (it is called stratum corneum) so that layer has a special influence on the UV radiation absorption. Black skin of the humans is thicker than skin of white humans and that's why transmits about forty percent of the ultraviolet rays, which are needed for production of vitamin D.
People who live in sunny climates and have dark pigments experience higher rate of mortality (not incidence) because of shortage of vitamin D and prostate cancer destroy their organisms, especially when they move to another areas that are divested of ultraviolet rays` exposure as a rule in winter months. The increase rate differs, and scientists falter to quote figures because of the fact that most of the migrant black populations as a rule have poor food and deficient health care that confuse data somewhat.
It is very interesting about cancer and vitamin D, that vitamin D also helps our organism at another cancer development stage. Tumor cells are new, but they are immortal cells, ripen and after that die off. Thanks to vitamin D derivatives have such possibility to promote growth and maturation of normal cells; some drug companies now try to design some patentable forms of anti-cancer therapy with vitamin D.
Thus, now you know enough about cancer and vitamin D, also about vitamin D cancer prevention, therefore your chances to avoid those problems are higher.
