Calcium and vitamin D cut breast cancer risk in pre-menopausal women

A study from researchers at Harvard Medical School suggest that pre-menopausal women who consume high amounts of calcium and vitamin D from diet and supplements could reduce their risk of breast cancer by up to 40 percent.

However, researchers note that post-menopausal women may not benefit from the mineral/vitamin combo.

Researchers assessed the medical history and food frequency questionnaires from over 10,500 pre-menopausal women and over 20,900 post-menopausal women.

After a 10-year follow up period, researchers found that pre-menopausal women with the highest intake of calcium had a 39 percent lower risk of breast cancer, while women with the highest intake of vitamin D had a 35 percent lower risk of the disease, compared to women with the lowest intakes.

No protective effect was observed in post-menopausal women.

While further studies are needed, these findings add to a growing body of research linking vitamin D intake to a decreased risk of cancer, including breast cancer.
