In conclusion, we still need further studies to evaluate the association of vitamin D insufficiency and cancer incidence and mortality, but the multiple health benefits of vitamin D and the easy, safe and inexpensive way by which vitamin D can be supplemented should already guide current public health strategies to achieve 25(OH)D levels of at least 75 nmol/l (30 ng/ml) in the general population.
