Rates for these cancers are two to three times higher than sunnier areas. Although excessive sun exposure may give rise to skin cancer patients have reduced rates of other cancers. One researcher estimates moderate sunning would prevent 30,000 annual cancer deaths in the United States Vitamin D may also go beyond cancer prevention and provide tumor therapy. Much ado has been made of pharmaceutical angiogensis inhibitors-agents that help inhibit the growth of new, undesirable blood vessels that tumors require for nutrient supply and growth. Laboratory tests have shown vitamin D to be a potent angiogenesis inhibitor.
Vitamin also works at another stage of cancer development.
Tumor cells are young, immortal cells that never grow, mature and die off. Because vitamin D derivatives have been shown to promote normal cell growth and maturation, drug companies today are attempting to engineer patentable forms of vitamin D for anti-cancer therapy.
