Low Vitamin D and cancer

Low vitamin D status may raise cancer risk NutraIngredients USA 11/30/06 "The link between vitamin D intake and protection from cancer dates from the 1940s when Frank Apperly demonstrated a link between latitude and deaths from cancer, and suggested that sunlight gave “a relative cancer immunity.”..."Vitamin D levels have been linked to skin colour – darker skinned people produce less vitamin D on exposure to the sun, relative to fair-skinned people...Giovannucci and his colleagues calculated that, after accounting for various risk factors, darker skinned men had a significantly higher risk of total cancer incidence (30 per cent increase), total cancer mortality (89 per cent increase) and death from digestive system cancers (124 per cent increase), than their white counterparts..."

The study doesn't prove low vitamin D causes cancer. But it appears that high levels of vitamin D do seem to help prevent and fight a very large number of organ cancers. You can either get it through exposure to the sun, or through the diet. There have been studies and meta studies that show UV exposure and the protective effect against organ cancers outweighs the risk of skin cancer. But obviously if you've had skin cancer or think you might be prone to it, that's a big reason to go the supplement route.
