Using food, vitamins, and other supplements to fight cancer

Many people want to know how they can help their body fight cancer by eating certain foods or taking vitamins or supplements. But, there are no studies that prove that any special diet, food, vitamin, mineral, dietary supplement, herb, or combination of these can slow cancer, cure it, or keep it from coming back. In fact, some of these products can cause other problems by changing how your cancer treatment works. Talk with your doctor, nurse, or dietitian before going on a special diet or taking any supplements. To avoid problems, be sure to follow their advice.
