Does not cause Ca: A number of different additives are present in food and drugs where in the latter instance they serve as preservatives. The minor cause of cancer is hereditary, while the major cause is from carcinogens or viruses. The effect of mercury is cumulative so that in diet or in vaccines, the mercury will migrate to neural tissue of brain and may in the long run diminish neural function.
