IARC has established a Working Group (WG) of international experts to investigate whether or not a causal relationship exists between vitamin D status and cancer risk. The WG has systematically reviewed the epidemiological literature on vitamin D and cancer and has performed a meta?analysis on observational studies of serum 25?hydroxyvitamin D levels (the best available biomarker of an individual’s vitamin D status) and the risk of colorectal, breast and prostate cancers and of colorectal adenomas.
