Vitamin D, Calcium Might Lower Breast Cancer Risk…Women who consume higher amounts of calcium and vitamin D may have a lower risk of developing premenopausal breast cancer, according to a recent report. Researchers used questionnaires to assess medical history, lifestyle and food frequencies of 10,578 premenopausal and 20,909 postmenopausal women, 45 and older. Every six months during the first year and every following year, participants returned follow-up questionnaires indicating whether they had been diagnosed with breast cancer. Over an average of 10 years of follow-up, 276 premenopausal women and 743 postmenopausal women developed breast cancer. Calcium and vitamin D intake were moderately associated with the lower risk of breast cancer before but not after menopause. The inverse associated in premenopausal women appeared more pronounced for more aggressive breast tumors. (Archives of Internal Medicine, volume 167, pages 1050-1059)
