Lack of Vitamin D: More Evidence Connected to Breast, Colon Cancer
Posted Oct 21 2010 8:26pm
Two new vitamin D studies from the University of Rochester Medical Center suggest intriguing ties between a deficiency of D and breast and colon cancer, particularly among African Americans.
The research adds to mounting evidence that some connection exists between vitamin D and cancer, although it is not yet known how vitamin D modifies or contributes to cancer risk. Evidence is also inconsistent as to whether vitamin D might be used for cancer prevention. Scientists believe it is possible that some of the benefits attributed to vitamin D may have more to do with body mass index or activity levels.
Still, in a retrospective study of 224 women being treated for breast cancer at the URMC James P. Wilmot Cancer Center, researchers found that 66 percent were either severely deficient or moderately deficient of vitamin D.
