Your multivitamin can give you cancer
CNN Medical Associate Producer
A new study with an alarming headline has been published in the American Journal of Clinical Nutrition that may have some Americans thinking twice before popping their daily vitamin.
The study looked at data from 35,000 Swedish women, ages 49 to 83, who were cancer-free at the beginning of a 10-year period. A decade later, they found that older women who took a multivitamin were 19 percent more likely to develop breast cancer compared with women who didn’t take a vitamin. That finding was true regardless of whether the women smoked or took postmenopausal hormones over that 10-year period.
