Calcium and Vitamin D associated with lower risk of breast cancer in pre-menopausal women

American scientists have found that women who consume higher amounts of calcium and vitamin D may have a lower risk of developing premenopausal breast cancer, in research published in the journal Archives of Internal Medicine.

In this study, researchers prospectively evaluated calcium and vitamin D intake and breast cancer incidence among approximately 11,000 premenopausal and approximately 21,000 postmenopausal women 45 years or older who were free of cancer and cardiovascular disease at the start of the study.

Over an average of 10 years, higher intakes of total calcium and vitamin D were moderately associated with a lower risk of breast cancer in premenopausal women.

Author’s conclusions: ‘Higher intakes of calcium and vitamin D may be associated with a lower risk of developing premenopausal breast cancer.’
