Unconventional Cancer Treatments

Appendix B: Glossary of Terms

Acupuncture: A treatment that involves piercing the skin with very fine needles at certain key "acupoints" on the body. Acupuncture is based on the theory that energy flows along specific pathways or "meridians" connecting the organs deep in the body with the acupoints on the surface of the body. The flow of energy is believed to be disrupted by disease, and may be restored to equilibrium by acupuncture.

Adjuvant: A substance added to a medical drug that enhances the effect of the active ingredient. In immunology, a substance added to a vaccine that non-specifically enhances its antigenicity. In cancer treatment, "adjuvant chemotherapy" refers to drug therapy used to complement surgical removal of the tumor.

Allopathy/allopathic practitioner: Terms used to refer to mainstream medicine its practitioners. The term was coined by Samuel Hahnemann, the founder of homeopathy, originally as a pejorative term, though it has largely lost that connotation.

Anthroposophy: A spiritual tradition encompassing all aspects of life, including medicine, founded by the Austrian-born clairvoyant Rudolf Steiner in the early 20th century.

Autogenous: Self-generated; originated within the body. As applied to bacterial vaccines, the term denotes those vaccines that are made for each specific patient from cultures originating from that patient, as opposed to stock vaccines which are made from standard cultures.

Autoimmune: Referring to a response of the immune system directed against the body's own tissue, an abnormal state (the immune system is designed to response foreign tissue) believed to contribute to a number of chronic diseases (e.g., rheumatoid arthritis, diabetes mellitus).

Behavioral treatments: Referring to treatments based on physical and mental activities, e.g., exercise, relaxation, qi gong.

Benign: Not malignant; in reference to tumors, lacking the capacity to invade normal tissue and metastasize to distant sites.

Biofeedback: A technique based on the theory that one can learn to regulate one's own internal state, including the autonomic nervous system, which had been thought to be beyond conscious control.

Biopsy: The removal and examination, usually microscopic, of tissue from the living body, performed to establish precise diagnosis.

Blinding: In randomized clinical trials, keeping secret which treatment is assigned to participants. When only the patient is kept unaware of his or her treatment assignment, the study is "single-blind." When the person administering treatment (e.g., the physician) also is unaware, the study is "double-blind." Additional layers of blinding can be added, as, for example, when a third individual (usually the evaluator of outcomes) also is unaware of treatment assignments.

Brucellosis: A generalized infection involving the reticuloendothelial system caused by species of microorganism genus Brucella, that is contracted through contact with goats, cattle, pigs, and dogs.

Cachexia: In cancer, the progressive wasting that occurs in the late stages of disease, resulting from derangements in various metabolic processes.

Cancer: A tumor with the potential for invading neighboring tissue and/or metastasizing to distant sites, or one that has already done so. Cancers are categorized into major classes by their cell types. See also carcinoma, sarcoma, lymphoma, and leukemia.

Carcinogen: An agent that causes cancer.

Carcinoma: A cancer arising from epithelial cells, including the external epithelia (mainly skin and linings of the gastrointestinal tract, lungs, and cervix) and the internal epithelia that line various glands (e.g., breast, pancreas, thyroid). See cancer.

Chemotherapy: The use of specific chemical agents to arrest the progress of, or eradicate, disease in the body.

Chiropractic: A system of treatment based on the theory that disease is produced by disruptions in the normal flow of a natural life force termed "Innate Intelligence." This life force flows through the nervous system and is disrupted by displacements of the spinal vertebrae called subluxations. Chiropractic manipulation is intended to correct the subluxations allowing the uninterrupted flow of Innate Intelligence to return the body to full health. As practiced currently in the United States, most chiropractic is limited to treating skeletal abnormalities.

Chiropractor: A practitioner of chiropractic.

Chronic: Lingering, lasting, as opposed to acute. A term used to describe persistent disease.

Clinical trial: A scientific research activity undertaken to define prospectively the effect and value of prophylactic, diagnostic, or therapeutic agents, devices, regimens, procedures, etc., applied to human subjects.

Control group: In a randomized clinical trial, the group receiving no treatment or some treatment with which the group receiving experimental treatment is compared. The control treatment is generally a standard treatment, a placebo, or no treatment. Compare experimental group.

Its biological activities include the ability to penetrate plant and animal tissues and to preserve living cells during freezing. In mainstream medical treatment, it has been shown efficacious for one condition, interstitial cystitis. It is used in a number of unconventional cancer treatment, applied topically in conjunction with other agents.

Drug: Any chemical or biological substance that may be applied to, ingested by, or injected into humans in order to prevent, treat, or diagnose disease or other medical conditions.

Endogenous: Developing or originating within the organism, or arising from causes within the organism.

Enema: A rectal injection for the purpose of clearing out the bowel, or administering drugs or food.

Etiology: The cause or origin (of disease).

Experimental group: In a randomized clinical trial, the group receiving the treatment being evaluated for safety and efficacy. The experimental treatment may be a new technology, an existing technology applied to a new problem, or an accepted treatment about whose safety or efficacy there is doubt. Compare control group.

Health fraud: False or unsupported claims for a medical treatment's effectiveness.

Homeopathy: A philosophy of treatment founded by Samuel Hahnemann (1755-1843), in which micro-doses of medicines are believed to stimulate the body's vital force. Some of these medicines are not known to contain even one molecule of the original compound per dose, but are considered by the homeopath to be extremely powerful. The power of these doses is enhanced by "succussion" (violent shaking) performed at various stages in their preparation.

Immune system: A specialized group of body cells and cell products that respond to foreign organisms and substances in the body. The cell products are largely immunoglobulins (antibodies), produced by specialized white blood cells known as lymphocytes. Some lymphocytes and various other cells of the immune system directly attack foreign organisms.

Immunity: The condition of being immune; an organism's capacity to resist disease. Immunity may be either innate or acquired. Innate immunity is natural or inherited. Acquired immunity may be active (resulting from either previous exposure to the disease-causing agent or vaccination) or passive (resulting from the transfer of preformed antibodies in immune serum or from mother to fetus).

Immunotherapy: Cancer treatment that produces antitumor effects primarily through the action of natural host defense mechanisms or by the administration of natural mammalian substances. Also called biotherapy and biological therapy.

In vitro: Literally, "in glass," pertaining to a biological process or reaction taking place in an artificial environment, usually a laboratory. Sometimes used to include the growth of cells from multicellular organisms under cell culture conditions.

In vivo: Literally, "in the living," pertaining to a biological process or reaction taking place in a living organism. In biomedical research, used to describe experiments or processes in whole animals (e.g., mice, rats, humans), as opposed to those in a test tube or other experimental system.

Macrobiotics: A lifestyle and diet adapted from the Far East and popularized in America by Michio Kushi and others. Macrobiotics is not primarily a treatment for cancer, but it is adopted by some cancer patients. The principles of the diet consist of balancing the "yin" and "yang" energies of foods. Different types of cancer are considered either yin or yang and the macrobiotic program must be adapted to the particular type of cancer and to individual traits.

Oral: Pertaining to the mouth, taken through of applied in the mouth as an oral medication.

Osteopathy: A system of treatment founded by Andrew Taylor Still (1828-1917) and based on the theory that the body is capable of making its own remedies against disease and other toxic conditions when it is in normal structural relationship and has favorable environmental conditions and adequate nutrition. It utilizes generally accepted physical, medicinal, and surgical methods of diagnosis and therapy, while placing chief emphasis on the importance of normal body mechanics and manipulative methods of detecting and correcting faulty structure.

Physician: An authorized practitioner of medicine, as one graduated from a college of medicine or osteopathy and licensed by the appropriate board.

Placebo effect: A beneficial effect of a medical technology that cannot be attributed to properties of the technology itself. Often considered psychologically-engendered well-being or improvement in a condition brought on by the belief of the patient that the technology itself is beneficial.

Placebo: A drug or procedure with no intrinsic therapeutic value. In a randomized clinical trial, a placebo is given to patients in control groups as a means to blind investigators and patients as to whether an individual is receiving the experimental or control treatment.

Pleomorphic: A term used in microbiology to refer to bacteria that change in size and shape during their life cycle (also called "cell wall deficient" bacteria).

Prognosis: A forecast as to the probable outcome of an attack of disease; the prospect as to recovery from a disease as indicated by the nature and symptoms of the case.

Recurrence: In cancer, the regrowth of tumor tissue after all evidence of it had apparently been eradicated either by surgery or other means (e.g., radiotherapy). A recurrence may occur at the site of the original tumor or elsewhere in the body, as metastatic disease.

Regression (or remission): In relation to cancer, regression refers generally to the shrinking of a tumor by other than surgical means. A complete regression occurs when a tumor that was at one time measurable disappears completely. Partial regression describes the condition where the measurable tumor is reduced by at least 50 percent in size.

Staging: In oncology, an attempt to define the true extent of cancer in its three compartments, TNM. These refer to the primary tumor (T), regional nodes (N), and metastasis (M). Subscripts ranging from 0 to 4 are used to denote size and degree of involvement; 0 indicates undetectable, and 1,2,3, and 4 a progressive increase in size or involvement.

Subcutaneous: Beneath the skin.

Systemic: Pertaining to or affecting the body as a whole.

Terminal: In cancer prognosis, forecasting death due to the growth and progression of the cancer.

Third-party payer: Private insurers or government insurance programs that pay providers for medical care given to patients they insure, either directly or by reimbursing patients for payments they make.

Toxicity: Referring to medical treatments, the degree to which they produce unwanted, adverse effects.

Treatment IND: A provision of the Federal Food, Drug and Cosmetic Act that allows patients with life-threatening or serious diseases to obtain certain drugs that are in late stages of clinical testing, but have not yet been approved by FDA for marketing.

Tumor: A new growth of tissue in which the multiplication of cells is uncontrolled and progressive. Also called neoplasm.

Unapproved drug: A drug that has not been approved by the FDA for marketing in the United States.

Unconventional Cancer Treatment: As used in this report, unconventional cancer treatments include the wide variety of treatments that fall outside the bounds of mainstream medicine. Other terms used by proponents to describe all or some of these treatments include: alternative, complementary, non-toxic, holistic, natural, and non-invasive. Those used by the sharpest of critics include: unproven, questionable, dubious, quackery, and fraudulent. The term unorthodox is used at times by both proponents and critics.

Vaccine: A preparation of living, attenuated, or killed bacteria or viruses, fractions thereof, or synthesized antigens identical or similar to those found in the disease-causing organisms, that is administered to produce or increase immunity to a particular disease.

Visualization: The use of mental imagery to create positive beliefs that will activate the body's defenses against disease. In one type of visualization, patients are taught to see their cancer cells as vulnerable and disorganized, and their treatment as powerful and directed only at the cancer cells, sparing the healthy cells. They are also instructed to see their immune systems flushing away the cancer cells.
