After the diagnosis of cancer in a child is made, many families complement conventional medical care with lifestyle changes including diet, exercise, environment, and mind-body therapies. Biomechanical, bioenergetic, and other therapies are also sometimes sought. These include massage, chiropractic, acupuncture/acupressure, therapeutic touch, Reiki, homeopathy, and prayer. Some of these complementary therapies have well-established roles in cancer therapy for children, whereas others are controversial and require more research.
