New research shows that bladder cells activate and respond to vitamin D, which can stimulate an immune response. Experts say this finding is important because the immune system may help prevent cancer by identifying and destroying abnormal cells before they develop into cancer. The body usually produces vitamin D through exposure to sunshine, but it’s also obtained from foods such as fatty fish, cheese, and eggs. Lead author Dr. Rosemary Bland writes, “As vitamin D is cheap and safe, its potential use in cancer prevention is exciting and could potentially impact on the lives of many people.” Society for Endocrinology, November 2016
