Low vitamin D levels have a direct correlation with triple-negative breast cancer, according to research presented at the American Society of Breast Surgeons meeting in Washington, D.C. Researchers looked at prognostic factors for 155 women treated for breast cancer between January 2009 and September 2010 at the University of Rochester Medical Center. According to a news release from URMC:
A growing number of physicians are already monitoring cancer patients and healthy people for vitamin D. Last fall the Institute of Medicine announced new daily recommended intakes of vitamin D for nearly all adults and children in the United States and Canada. Although the IOM did not specifically address vitamin D and cancer, it reported that 600 IUs daily meets the needs of most people. Higher amounts are often prescribed to cancer patients; sometimes a weekly dose of 50,000 IU is necessary to treat severely deficient people.
