what to eat if you have cancer

years ago when i was working in health and body store, there was one girl working there and her mom had had cancer. She told me he mom became a 100% vegan eating only organic stuff and in two years she improved so much that it considered to be combat.
well, i dont want to say that every one should do it, i have no idea wjat stage or what type of cancer she had, but i ve heard about nutrition connection to pretty much any illness… so… we all, who have it, had it, or dont ever want to have it , should look into nutrition… very important…
