Low vitamin D levels are associated with some cancers and with worse outcomes in other cancers, but taking supplements does not appear to help people with prostate cancer.[29] Currently evidence is insufficient to support supplementation in those with cancer,[29] although several studies suggest a slightly lower incidence of cancer when subjects were taking the recommended dose of vitamin D each day and one study does support the lower incidence of metastasis in cancer patients when they were found to be taking the recommended daily dose of vitamin D. Results for a protective or harmful effect of vitamin D supplementation in other types of cancer are inconclusive, [7][30] although the number of studies which call for more in-depth and thorough research centered on the connection between vitamin D and the development of any type of cancer reveal a hole in current scientific study.
