There's more evidence the "sunshine vitamin" has anti-cancer properties: according to the report, breast cancer patients with low levels of vitamin D were more likely to die of their disease or have it spread.

Researchers say more then three-quarters of woman with breast cancer had a vitamin D deficiency. What they don't know is why there is the association.

This study involving more than 500 women comes from Mount Sinai Hospital in Toronto. Researchers say it would be a good idea for women to have their vitamin D levels checked so a doctor can prescribe safe amounts of the supplement if needed.
