Low vitamin D levels linked to increased risk of bladder cancer

Vitamin D deficiency is associated with an increased risk of developing bladder cancer, according to a systematic review of seven studies presented today at the Society for Endocrinology annual conference in Brighton. Though further clinical studies are needed to confirm the findings, the study adds to a growing body of evidence on the importance of maintaining adequate vitamin D levels.

Vitamin D, which is produced by the body through exposure to sunshine, helps the body control calcium and phosphate levels. Vitamin D can also be obtained from food sources such as fatty fish and egg yolks. Previous studies have linked vitamin D deficiency with a host of health problems including cardiovascular disease, cognitive impairment, autoimmune conditions, and cancer.

In countries with low levels of sunlight, it is difficult to obtain enough vitamin D from food alone. In the UK, 1 in 5 adults are vitamin D deficient and 3 in 5 have low levels. This is especially prevalent in people with darker skin: in winter, 75% of dark-skinned people in the UK are vitamin D deficient.
