“…CAM perceives health and disease in a more holistic perspective of body, mind, and spirit. 1,2 There is a broad array of CAM practices, which can be classified into the following major categories: (1) alternative medical systems that evolved apart from conventional medicine, such as Ayurveda and homeopathy; (2) energy therapies involving the use of energy fields, such as Qigong and Reiki; (3) exercise therapies that include health-enhancing systems of exercise and movement, such as Tai chi; (4) body-based methods, including the manipulation and/or movement of body parts, such as chiropractic; (5) mind-body interventions that aim to enhance the mind's capacity to affect bodily functions and symptoms, such as meditation or art therapy; (6) nutritional therapeutics, such as nutrients and nonnutrients, bioactive food components, and specific foods such as a macrobiotic diet or vegetarianism; (7) pharmacologic and biologic treatments that use prescription drugs, hormones, complex natural products, or vaccines not yet accepted in mainstream medicine, such as antineoplastons; and (8) spiritual therapies that focus on a person's deep, often religious, beliefs and feelings, such as spiritual healing. 2 Approximately half of the patients with cancer worldwide use CAM as part of their oncologic care.…”
