You are absolutely correct. Many cancers are the result of a poor diet (soda, fast food, and other nutritionally bankrupt "foods"). Chemo destroys the very immune system that your body needs to fight the cancers.
The surgeon himself told me that at first they thought they had removed the wrong lobe. The tumor was obvious in an X-ray they took the day before the surgery.
I don't pretend to have all the answers but I do believe that the diet alone, along with prayer of course, might reverse cancers that are considered inoperable or badly metastasized.
