Vitamin D Status is Not Associated with Risk for Less Common Cancers

Despite hopes that higher blood levels of vitamin D might reduce cancer risk, a large study finds no protective effect against non-Hodgkin lymphoma or cancer of the endometrium, esophagus, stomach, kidney, ovary, or pancreas. In this study, carried out by researchers from the National Cancer Institute (NCI), part of the National Institutes of Health, and many other research institutions, data based on blood samples originally drawn for 10 individual studies were combined to investigate whether people with high levels of vitamin D were less likely to develop these rarer cancers.
