Although excessive sun exposure may give rise to skin cancer, researchers as early as 1936 were aware that 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. 3 Vitamin D may also go beyond cancer prevention and provide tumor therapy. Laboratory tests have shown vitamin D to be a potent angiogenesis inhibitor. 4 Vitamin D also works at another stage of cancer development.
Tumor cells are young, immortal cells that never grow up, 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 patent able forms of vitamin D for anti-cancer therapy. Determine Your Current State of Health.
