A high dose of Vitamin D, Omega 3 fatty acid, and a simple home strength training program has been shown to reduce the risk of cancer by 61% in the senior population of 70 and above. Cancer is dubbed the second leading cause of mortality in adults with the risk ratio directly proportional to increasing age.

The study conducted by Dr. Heike Bischoff-Ferrari at University Hospital Zurich determined the combined benefit of these three affordable public interventions in the prevention of cancers. The study results were published in ‘Frontiers of Aging’ and highlighted the mechanism of inhibiting cancer growth by Vitamin D. Similarly, Omega 3 fatty acids inhibit the transformation of normal cells into cancer cells while exercise improves the immune function and decreases cell inflammation.  

The study was a randomized controlled trial conducted over three years in five European countries. The subjects were randomly segregated into eight different groups and received a check-up call every three months followed by a complete check annually. The results showed a significant decrease in the risk percentage however further studies are required to verify the benefits of the combination treatment for cancer over a longer period.
