Cancer risks can be minimized--in some cases--but they cannot really be eliminated, because there are so many possible areas where tumors can develop and various ways in which they can form (genetically-inherited mutations, acquired mutations, etc.) Billions of cell divisions happening over and over, uncountable number of times in a life of an animal (and humans). Supplements to prevent cancer are pretty much a hoax. If it were that simple, such supplements would be supported by government-regulated health services, and human cancer rates, for example, would plummet.
