Doctors receive very little education on nutrition, therefore, they prescribe what they are taught: drugs or surgery. I have had a pancreatic tumor and metatastic liver cancer, but am now cancer-free. I've done a lot of research on how to beat cancer and the answer seems to be good nutrition and exercise. I'm a firm believer that the earth provided us with the tools we need to heal ourselves, because that is what the body is designed to do, if treated correctly. I walk daily, get lots of rest, drink green or black tea daily, and take a nutritional supplement called Ambrotose. (It is comprised of ingredients from vine ripened fruits and vegetables, colostrum, and aloe.) Most of our produce is no longer vine-ripened so we don't get the nutrients we need. Doctors don't believe this, though. Check out the website Glycoscience.org. It explains our nutritional needs better than I can.
