Stress reduction will not only improve your chances of recovering from cancer it will probably decrease your chances of getting it in the first place. Exercise, relaxation, and behavioral changes are the most important ways to reduce your stress. I recommend a combination of aerobic and relaxing forms of exercise. By relaxing forms, I mean exercise like hatha yoga and tai chi. Both relaxation and behavioral changes can be achieved by self-hypnosis and certain kinds of meditation.
