"ACIDOSIS IS THE CAUSE OF MOST CANCERS. SO REMOVE THE CAUSE! The major cause of most diseases and cancers, including breast cancer, pancreatic cancer, colon cancer, liver cancer, lung cancer and even skin cancer, is acidosis. Acidosis causes body tissue to become acidified. Acidified body tissue lacks the proper amount of oxygen required to keep them healthy. Unhealthy body tissue can develop into cancerous cells in any part of your body".....

So...Expect a spike in cancer rates in millions of people worldwide?
