Animal fat ingested by bacteria in the human gut metabolizes into cancer causing toxins. Meat eaters have twice as much of this toxin in their blood stream as vegetarians. Walking removes the toxin. That is why cancer improves with exercise. Water Fasting improves digestion, the real cause of all sickness- poor digestion. Water Fasting gives the body a chance to digest all unwanted growths, dead cells, etc. I am sad that this lady has chosen to see mds that are not nutritionally aware. They will not bring about a change to her health, as the surgery will not cure what caused the cancer in the first place.
