According to the International Agency for Research in Cancer "...80-90 per cent of human cancer is determined environmentally and thus theoretically avoidable." (5) Environmental causes of cancer include lifestyle factors such as smoking, a diet high in animal products and low in fresh fruit & vegetables, excessive exposure to sunlight, food additives, alcohol, workplace hazards, pollution, electromagnetic radiation, and even certain pharmaceutical drugs and medical procedures. But unfortunately, as expressed by medical historian Hans Ruesch, "Despite the general recognition that 85 per cent of all cancers is caused by environmental influences, less than 10 per cent of the (U.S.) National Cancer Institute budget is given to environmental causes. And despite the recognition that the majority of environmental causes are linked to nutrition, less than 1 per cent of the National Cancer Institute budget is devoted to nutrition studies. And even that small amount had to be forced on the Institute by a special amendment of the National Cancer Act in 1974."
According to Dr. Robert Sharpe, " . . . in our culture treating disease is enormously profitable, preventing it is not. In 1985 the U.S., Western Europe and Japanese market in cancer therapies was estimated at over 3.2 billion pounds with the 'market' showing a steady annual rise of 10 per cent over the past five years. Preventing the disease benefits no one except the patient. Just as the drug industry thrives on the 'pill for every ill' mentality, so many of the leading medical charities are financially sustained by the dream of a miracle cure, just around the corner."
