Vitamin D's role in breast cancer prevention is still up for debate. There's some evidence that vitamin D does protect against the disease, but a 2008 National Women's Health Initiative study of more than 36,000 menopausal women found that those who took 400 international units (IUs) of vitamin D per day were no more protected from breast cancer than those who swallowed a placebo (a sugar pill containing no active ingredients). Plus, the Institute of Medicine recently said there's no evidence to show that vitamin D helps prevent breast cancer. Even so, some experts argue that more research needs to be done to see if higher doses of vitamin D might be useful in fighting breast cancer.

Cells need to be turned on to fight breast cancer; vitamin D can penetrate cells and turn on the genetic code to fight cancer.A study shows that vitamin D interacts with some genes associated with breast cancer.
