A growing body of research links the prevalence of cancer with
vitamin D deficiency. We’ve seen it connected to breast and
colon cancer, as well as melanoma (the most deadly form of skin
cancer), but a new study out of Spain says people who are
deficient in what’s known as the “sunshine vitamin” are also at
a higher risk of bladder cancer. According to the Journal of the
National Cancer Institute, people with the lowest levels of
25-hydroxy-vitamin D3 were 1.83 times more likely to have
bladder cancer. In the United States, bladder accounts for
15,000 deaths annually, with over 73,000 new cases each and
every year. In Spain, where the study was conducted, bladder
cancer rates are some of the highest in the world. The
researchers looked at blood samples from 1,125 patients with
bladder cancer from 18 different Spanish hospitals. After
accounting for those with the most aggressive forms of the
cancer, they found those with the lowest levels of vitamin D to
be 5.94 times more likely to have the disease. “These r
