Higher Levels of Vitamin D have been associated with a reduced risk of colon cancer in many observational studies. A new analysis has found a possible reason. A malignant tumour contains not just cancer cells but many types of cells, some of which affect how fast a tumour may grow or spread. Vitamin D, the authors suggest, interacts with the immune system to prevent the growth of this type of malignancy.
