Higher serum 25-hydroxyvitamin D [25(OH)D] concentrations have been associated with a lower risk of multiple cancer types across a range of 25(OH)D concentrations.
The objective of this analysis was to investigate whether the previously reported inverse association between 25(OH)D and cancer risk could be replicated, and if a 25(OH)D response region could be identified among women aged 55 years and older across a broad range of 25(OH)D concentrations. This paper concludes that 25(OH)D concentrations 40 ng/ml were associated with substantial reduction in risk of all invasive cancers combined.
