I personally have abandoned my old ways of eating. No more caffeine, caffeine can cause urging and irritate an already irritated organ. I drink decaffeinate green tea now,
I don't smoke or drink.
I have made it point to eat a diet rich in nutrients found in colorful fruits and vegetables. And I eat allot now.
No junk food, no processed food, or as little as possible.
A diet rich in protein, less the fat, Whey protein concentrates Blended with blueberry's or other organic fruit extracts instead of milk for breakfast to start the day.
I eat much smaller meals but more of them.
I snack on a variety of nuts (from bulk) mixed in with dehydrated cherry's, cranberry's, raisins in the form of a home made trail mix sticking with the better for you nuts.
IMHO, I have lost 25 pounds in 8 weeks and my blood pressure is dropping, I have more energy and don't go into food overload.
Just common sense stuff. High fiber breads and cereals.
If your going to have cancer, you should be healthy, your own body can do wonders.
