Abstract
Many therapies have been proposed for the treatment of cancer. Some of these therapies disappear with time, while others remain highly visible. Three cancer therapies still in use and highly visible today are named Gerson, Kelley, and the Kelley Modified. The Kelley and the Kelley Modified therapies are based on the theory that cancer is caused by a deficiency of pancreatic enzymes. Gerson, in contrast, believed that cancer is caused from both an accumulation of toxins systemically and a deterioration of the body's metabolism. All three therapies treat the whole person. The physical, emotional, psychological, and spiritual aspects of the client are addressed, and each therapy has the client take an active role in the healing process. Other similarities of the three therapies are: the inclusion of fresh fruits, fresh vegetables, fresh fruit juices, fresh vegetable juices, and whole grains. Sugar, processed foods, meat, salt, and dairy products are avoided. Differences between the therapies are the adjunctive treatments recommended, the detoxication regimens used, and the length of time clients are on the nutritional programs. Various degrees of effectiveness have been demonstrated by all three therapies.
