There are many, many individuals including doctors, who have refused mainstream cancer treatments and instead treated their cancer through nutrition.
There is much to learn if you open your mind. My mother is 82 and was diagnosed with NHL 20 months ago. Her doctors told her she wouldn't live 4 weeks if she didn't opt for 12 months (16 to 18 treatments) of CHOP. She has treated her cancer holistically and has changed her diet and is now taking digestive enzymes, probiotics (as opposed to antibiotics). She's amazing and her doctors are shocked.
