The Association of Vitamin D Deficiency with Colorectal Cancer: A Wake-up Call for Physicians and Health Authorities %R %X Although there is evidence that vitamin D deficiency leads to the development of several cancers, including colorectal cancer, research has shown gaps in establishing a relationship between hypovitaminosis D and the incidence of colorectal cancer. There are controversial reports and inadequate scientific evidence about the role of age and race-specific dosage of vitamin D supplementation for chemoprevention.
