If you want to fight cancer, you must have a diet that fights stress, body acidity and alkaline fixing foods. You can avoid the huge costs of cancer treatment associated with chemotherapy which is actually a poison therapy that doesn't work 100 percent. Better to fight off stress and cancer by eating antioxidant laden fruits all the time like the soursop or guyabano, a very delicious tropical fruit that you can snack on or turn into healthy juices.
