This is a Cancer that forms in the tissues of the colon (the longest part of the large intestine). We might add that most colon cancers are adenocarcinomas (cancers that begin in cells that make and release mucus and other fluids). A diet mostly of cooked and processed foods devoid of enzymes is the main cause of colon cancer. Enzymes are especially found in raw foods. By the time the digestion process is in the final stages if the food is devoid of enzymes the colon which is the final process of digestion is robbed of necessary enzymes for proper digestion. Eventually this is a major contributing factor in Colon cancer.
