Vitamin D and The Relationship to Colon Cancer
Almost every week there a new story about vitamin D and its relationship with some health outcome. Recently a new paper was published that examined the relationship between vitamin D levels and colorectal cancer risk. Vitamin D has for some time been associated with colorectal cancer, in the belief that it can lower colorectal cancer risk via anti-proliferative, pro-apoptotic, and anti-angiogenic properties.
The evidence for supplementation with vitamin D is not that convincing. However, given the modest benefit, low cost, and relative lack of side effects, vitamin D supplementation at modest doses is safe and is not likely to cause harm.
There is little support in treatment guidelines for vitamin D supplementation to prevent colon cancer. However, it adds to the body of evidence about vitamin D and cancer. It would seem the safest things to do to avoid colorectal cancer would be to ensure that you’re getting adequate vitamin D in your diet.
