In another study, published last week in the American Journal of Epidemiology, researchers reported that increased exposure to sunlight, which boosts vitamin D levels, may reduce the risk of advanced breast cancer in light-skinned women.
The study compared 1,788 breast cancer patients in San Francisco with a control group of 2,129 women who did not have breast cancer. The study participants had a wide range of natural skin colors. Vitamin D may help slow breast cancer cell growth, the researchers speculated. But the results aren't an endorsement to sunbathe. Instead, they said, vitamin D from diet and supplements may someday be recommended to help reduce breast cancer risk.
