Researchers say breast cancer patients with higher levels of Vitamin D have higher survival rates, especially premenopausal women. The study, published in the Journal of the American Medical Association Oncology, used date from more than 1,500 hundred survivors over the course of 7 years. During that time, women with vitamin D levels over 25 nanograms had a 28 percent higher likelihood of surviving when compared to women with levels under 17 nanograms.
Scientists say higher vitamin D levels had an even stronger impact on premenopausal women. The study considered many factors including the tumor stage, grade and type.
The Institute of Medicine recommends 600 units of vitamin D daily for people under 70 and 800 for people over 70.
