Colon Cancer Reduced with Antioxidants

Colon cancer is the second leading cancer killer in the U.S.  In fact, in 2009, 136,717 people were diagnosed with colon cancer and 51,849 died from it.(1)  Colonoscopies are one of the most common medical procedures done today.  A colonoscopy is performed in order to identify a growth or a polyp at an early stage so that it can be removed it before it becomes cancerous.  Colonoscopies are one of the few preventive procedures in conventional medicine that actually improve mortality.

It is well known that patients who have colonic polyps removed at an increased risk of recurrence.  A recent study looked at the efficacy of using antioxidants to prevent recurrent colonic polyps in patients who have undergone colonoscopic removal of polyps.(2)

The scientists conducted a randomized, double-blind placebo-controlled trial which began in 1988.  411 subjects were randomized to receive either a placebo or an active compound—taken daily–containing selenium (200ug), zinc (30mg), vitamin A (2mg), vitamin C (180mg), and vitamin E (30mg).

The authors found that the 15-year cumulative incidence of recurrent polyps in the antioxidant group was 39% reduced as compared to the placebo group.

Comments:  This is an important study as colon cancer affects too many people.   Simply taking an antioxidant supplement significantly reduced the recurrence of pre-cancerous lesions in the colon. Antioxidant therapy is inexpensive and has little side effects.  It makes sense to ensure that you eat food high in antioxidants—fruits and vegetables.  Avoid food that depletes the body of antioxidants such as refined carbohydrates—bread, pasta, and cereal made from refined sources.

The results of this study are not surprising to me.  I have seen the positive results patients experience when they correct nutrient imbalances.  I suggest supplementing with a good multivitamin that has natural sources of nutrients.  Biomultiplus from Biotics Research is one such product.  A health care practitioner knowledgeable about natural products can help you choose a product that is optimal for your personal biochemistry.
