Study Links Vitamin D Status to Cancer Risk

Vitamin D and CancerA new cohort study finds Vitamin D levels may have an effect on a person’s risk of developing cancer.  An inverse association between blood levels of Vitamin D and the risk of developing liver cancer and total cancer.

Data from over 33,500 adults between the ages of 40 and 69 who participated in the Japan Public Health Centre-based Prospective (JPHC) study was used for this study.  Participants were observed over a period of 16 years.  During this study period over 3,300 new cases of cancer were reported.  A sub grouping of over 4,000 participants was also studied.

Participants who were in the 3 highest groups of serum blood levels of Vitamin D showed a reduction of between 20% – 25% in the risk for developing all types of cancers and a reduction of between 30% and 55% in the risk for developing liver cancer.   It was observed that after having reached a certain level of serum Vitamin D further risk reductions were not seen in the total cancer risk reductions; this is called a ceiling effect.

A significant inverse association between serum Vitamin D levels and pre-menopausal breast cancer were also seen, however the same association was not seen for prostate or lung cancers.

Further studies are needed to clarify the optimal amounts of serum Vitamin D levels needed for cancer prevention and to clarify the dose-response pattern.
