You can use any diet you want to try to avoid cancer. Some diets and exercise seem to reduce the risk.
But once you get diagnosed with cancer, for god's sake listen to your oncologist. The strategy at that point changes entirely, and diets are not going to reverse your cancer. Steve Jobs might be alive today if he hadn't dicked around with alternative approaches for so long. My mom survived because although she wanted to try alternative approaches, all 3 of her kids insisted that she listen to her oncologist.
Hi Mom!
