From the Vitamin D Council
Solar radiation is associated with a decreased incidence and mortality rate of leading cancers in the United States, according to a new study published in the journal Dermato-Endocrinology.
Research continues to support the role of vitamin D and sun exposure in maintaining a healthy immune system. Vitamin D not only enables proper communication between immune cells, but also promotes programmed cell death (apoptosis) when a cell is no longer needed or is not functioning properly.
Since cancer occurs as a result of uncontrolled cell division, researchers believe that vitamin D is crucial for decreasing the risk of cancer through its relationship with the immune system. There have been many studies published over the years that have supported this relationship. Dr. Bill Grant, a board member of the Vitamin D Council, discussed the latest research on the relationship between vitamin D and ultraviolet B radiation (UVB) on cancer back in 2013.
The researchers gathered the NLDAS statistics for the continental United States from 1999-2011. The age-adjusted invasive cancer incidence and mortality rate was collected from the Centers for Disease Control and Prevention (CDC) during the same time period. Invasive cancers refer to cases in which cancer has spread to surrounding tissues.
