Max Gerson (October 18, 1881 – March 8, 1959) was a German-born American physician who developed the Gerson Therapy, a dietary-based alternative cancer treatment that he claimed could cure cancer and most chronic, degenerative diseases.
Gerson described his approach in the book A Cancer Therapy: Results of 50 Cases (1958). The National Cancer Institute evaluated Gerson's claims and concluded that his data showed no benefit from his treatment.The therapy is both ineffective and dangerous.
Gerson was born to a Jewish family in Wongrowitz, German Empire (Wągrowiec, now in Poland), on October 18, 1881. In 1909, he graduated from the Albert-Ludwigs-Universität Freiburg. He began practicing medicine at age 28 in Breslau (Wrocław, now in Poland), later specializing in internal medicine and nerve diseases in Bielefeld.By 1927, he was specializing in the treatment of tuberculosis, developing the Gerson-Sauerbruch-Hermannsdorfer diet, claiming it was a major advance in the treatment of tuberculosis. Initially, he used his therapy as a supposed treatment for migraine headaches and tuberculosis. In 1928, he began to use it as a claimed treatment for cancer. When the Nazis came to power in 1933 Gerson left Germany, emigrating to Vienna, where he worked in the West End Sanatorium. Gerson spent two years in Vienna, before moving to France in 1935, associating with a clinic near Paris before moving to London in 1936. Shortly thereafter, he moved to the United States, settling in New York City.
Gerson emigrated to the United States in 1936, passed his medical board examination, and became a U.S. citizen in 1942. [ citation needed ] In the U.S., Gerson applied his dietary therapy to several cancer patients, claiming good results, but other workers found his methodology and claims unconvincing. Proponents of the Gerson Therapy believe a conspiracy headed by the medical establishment prevented Gerson from publishing proof that his therapy worked. In 1958, Gerson published a book in which he claimed to have cured 50 terminal cancer patients: A Cancer Therapy: Results of 50 Cases. In 1953, Gerson's malpractice insurance was discontinued and, in 1958, his medical license in New York was suspended for two years. Gerson died March 8, 1959 of pneumonia.The rest of his family died at the hands of the Nazis.
Initially, Gerson used his therapy as a treatment for migraine headaches and tuberculosis. In 1928, he began to use it as a supposed treatment for cancer.
Gerson Therapy is based on the belief that disease is caused by the accumulation of unspecified toxins, and attempts to treat the disease by having patients consume a predominantly vegetarian diet including hourly glasses of organic juice and various dietary supplements. Animal proteins are excluded from the diet under the unproven premise that tumors develop as a result of pancreatic enzyme deficiency.In addition, patients receive enemas of coffee, castor oil and sometimes hydrogen peroxide or ozone.
After Gerson's death, his daughter Charlotte Gerson (March 25, 1922 - February 10, 2019) continued to promote the therapy, founding the "Gerson Institute" in 1977.The original protocol also included raw calf's liver taken orally, but this practice was discontinued in the 1980s after ten patients were hospitalized (five of them comatose) from January 1979 to March 1981 in San Diego, California, area hospitals due to infection with the rare bacterium Campylobacter fetus. This infection was seen only in those following Gerson-type therapy with raw liver (no other cases of patients having sepsis with this microbe, a pathogen in cattle, had been reported to Centers for Disease Control and Prevention in the previous two years). Nine of ten hospitalized patients had been treated in Tijuana, Mexico; the tenth followed Gerson therapy at home. One of these patients who had metastatic melanoma died within a week of his septic episode. Many of the patients had low sodium levels, thought to be associated with the very low sodium Gerson diet. The photographer Garry Winogrand died of gallbladder cancer in a Gerson Clinic in Tijuana.
Gerson's therapy has not been independently tested or subjected to randomized controlled trials, and thus is illegal to market in the United States.The Gerson Institute promotes the therapy by citing patient testimonials and other anecdotal evidence. Gerson published a book discussing the alleged success of the therapy in 50 patients, but a review by the U.S. National Cancer Institute was unable to find any evidence that Gerson's claims were accurate. The NCI found that no in vivo animal studies had been conducted. Similarly, case series by Gerson Institute staff published in the alternative medical literature suffered from methodological flaws, and no independent entity has been able to reproduce the claims.
Attempts to independently check the results of the therapy have been negative. A group of 13 patients sickened by elements of the Gerson Therapy were evaluated in hospitals in San Diego in the early 1980s; all 13 were found to still have active cancer.An investigation by Quackwatch found that the institute's claims of cure were based not on actual documentation of survival, but on "a combination of the doctor's estimate that the departing patient has a 'reasonable chance of surviving', plus feelings that the Institute staff have about the status of people who call in".
A 1994 article in the Journal of Naturopathic Medicineattempted to follow 39 Gerson patients in Tijuana. Patient interviews were used to confirm the existence and stage of cancer; most patients were unaware of the stage of their tumor, and medical records were not available. Most patients were lost to follow-up; of the patients successfully followed, 10 died and six were alive at their last follow-up. Review of this study pointed out its "obvious flaws", including "the majority of patients lost to follow-up, lack of access to detailed medical records, and reliance upon patients for disease stage information"; the authors themselves regarded the results as unclear.
The American Cancer Society reported that "[t]here is no reliable scientific evidence that Gerson therapy is effective in treating cancer, and the principles behind it are not widely accepted by the medical community. It is not approved for use in the United States."In 1947, the National Cancer Institute reviewed 10 claimed cures submitted by Gerson; however, all of the patients were receiving standard anticancer treatment simultaneously, making it impossible to determine what effect, if any, was due to Gerson's therapy. A review of the Gerson Therapy by Memorial Sloan-Kettering Cancer Center concluded: "If proponents of such therapies wish them to be evaluated scientifically and considered valid adjuvant treatments, they must provide extensive records (more than simple survival rates) and conduct controlled, prospective studies as evidence". In 1959, the National Cancer Institute (NCI) again reviewed cases of patients treated by Gerson. The NCI found that the available information did not prove the regimen had benefit. Cancer Research UK states that "Available scientific evidence does not support any claims that Gerson therapy can treat cancer [...] Gerson therapy can be very harmful to your health."
Gerson therapy can lead to several significant health problems. Serious illness and death have occurred as a direct result of some portions of the treatment, including severe electrolyte imbalances. Continued use of enemas may weaken the colon's normal function, causing or worsening constipation and colitis. Other complications have included dehydration, serious infections and severe bleeding.
The therapy may be especially hazardous to pregnant or breast-feeding women.
Coffee enemas have contributed to the deaths of at least three people in the United States. Coffee enemas "can cause colitis (inflammation of the bowel), fluid and electrolyte imbalances, and in some cases septicemia".The recommended diet may not be nutritionally adequate. The diet has been blamed for the deaths of patients who substituted it for standard medical care.
Relying on the therapy alone while avoiding or delaying conventional medical care for cancer has serious health consequences.Jessica Ainscough, better known as "The Wellness Warrior", was a major proponent of the Gerson diet after her diagnosis with cancer. She rejected medical treatment and followed the diet strictly, documenting her progress in a popular blog. She died from the cancer in February 2015, aged 30.
An enema, also known as a clyster, is an injection of fluid into the lower bowel by way of the rectum. Also, the word enema can refer to the liquid so injected, as well as to a device for administering such an injection.
Quackery, often synonymous with health fraud, is the promotion of fraudulent or ignorant medical practices. A quack is a "fraudulent or ignorant pretender to medical skill" or "a person who pretends, professionally or publicly, to have skill, knowledge, qualification or credentials they do not possess; a charlatan or snake oil salesman". The term quack is a clipped form of the archaic term quacksalver, from Dutch: kwakzalver a "hawker of salve". In the Middle Ages the term quack meant "shouting". The quacksalvers sold their wares on the market shouting in a loud voice.
Orthomolecular medicine is a form of alternative medicine that aims to maintain human health through nutritional supplementation. The concept builds on the idea of an optimal nutritional environment in the body and suggests that diseases reflect deficiencies in this environment. Treatment for disease, according to this view, involves attempts to correct "imbalances or deficiencies based on individual biochemistry" by use of substances such as vitamins, minerals, amino acids, trace elements and fatty acids. The notions behind orthomolecular medicine are not supported by sound medical evidence, and the therapy is not effective; even the validity of calling the orthomolecular approach a form of medicine has been questioned since the 1970s.
Quackwatch is a United States–based website, self-described as a "network of people" founded by Stephen Barrett, which aims to "combat health-related frauds, myths, fads, fallacies, and misconduct" and to focus on "quackery-related information that is difficult or impossible to get elsewhere". Since 1996 it has operated the alternative medicine watchdog website quackwatch.org, which advises the public on unproven or ineffective alternative medicine remedies. The site contains articles and other information criticizing many forms of alternative medicine.
Proponents of Metabolic typing believe that each person has a unique metabolism, and that the proportion of macromolecules which are optimal for one person may not be for a second, and could even be detrimental to them.
Megavitamin therapy is the use of large doses of vitamins, often many times greater than the recommended dietary allowance (RDA) in the attempt to prevent or treat diseases. Megavitamin therapy is typically used in alternative medicine by practitioners who call their approach orthomolecular medicine. Vitamins are useful in preventing and treating illnesses specifically associated with dietary vitamin shortfalls, but the conclusions of some medical research are that the claims of disease treatment by advocates of megavitamin therapy are unsubstantiated by the available evidence. This seems to point to doses of any vitamin greatly in excess of nutritional requirements resulting either in toxicity or in the excess simply being metabolised; thus the evidence in favour of vitamin supplementation supports only doses in the normal range. Critics have described some aspects of orthomolecular medicine as food faddism or even quackery. Research on nutrient supplementation in general suggests that some nutritional supplements might be beneficial, and that others might be harmful; several specific nutritional therapies are associated with an increased likelihood of the condition they are meant to prevent.
Gary Michael Null is an American talk radio host and author who advocates for pseudoscientific alternative medicine and produces a line of questionable dietary supplements.
William Donald Kelley was an orthodontist who developed "non-specific metabolic therapy," an alternative cancer treatment, now known to be ineffective, which he based on the unsubstantiated belief that "wrong foods [cause] malignancy to grow, while proper foods [allow] natural body defenses to work."
Hulda Regehr Clark was a Canadian naturopath, author, and practitioner of alternative medicine. Clark claimed all human disease was related to parasitic infection, and also claimed to be able to cure all diseases, including cancer and HIV/AIDS, by "zapping" them with electrical devices which she marketed. Clark wrote several books describing her methods and operated clinics in the United States. Following a string of lawsuits and eventual action by the Federal Trade Commission, she relocated to Tijuana, Mexico where she ran the Century Nutrition clinic.
The specific carbohydrate diet (SCD) is a diet originally created to manage celiac disease; it limits the use of complex carbohydrates. Monosaccharides are allowed, and various foods including fish, aged cheese and honey are included. Prohibited foods include cereal grains, potatoes and lactose-containing dairy products. It is a gluten-free diet since no grains are permitted.
Hoxsey Therapy or Hoxsey Method is an alternative medical treatment promoted as a cure for cancer. The treatment consists of a caustic herbal paste for external cancers or an herbal mixture for "internal" cancers, combined with laxatives, douches, vitamin supplements, and dietary changes. Reviews by major medical bodies, including the U.S. Food and Drug Administration (FDA), the National Cancer Institute, the American Cancer Society, M. D. Anderson Cancer Center, and Memorial Sloan-Kettering Cancer Center, have found no evidence that Hoxsey Therapy is an effective treatment for cancer. The sale or marketing of the Hoxsey Method was banned in the United States by the FDA on September 21, 1960 as a "worthless and discredited" remedy and a form of quackery.
Alternative cancer treatment describes any cancer treatment or practice that is not part of the conventional standard of cancer care. These include special diets and exercises, chemicals, herbs, devices, and manual procedures. Most alternative cancer treatments do not have high-quality evidence supporting their use. Concerns have been raised about the safety of some of them. Some have even been found to be unsafe in certain settings. Despite this, many untested and disproven treatments are used around the world. Promoting or marketing such treatments is illegal in most of the developed world.
A coffee enema is the injection of coffee into the rectum and colon via the anus, i.e., as an enema. There is no medical, scientific evidence to support any positive health claim for this practice, and medical authorities advise that the procedure may be dangerous. Coffee enemas carry a risk of adverse effects, some of them serious, including infection, seizures, heart and lung problems, and death.
Nicholas James Gonzalez, M.D., was a New York-based physician known for developing the Gonzalez regimen, an alternative cancer treatment. Gonzalez's treatments are based on the belief that pancreatic enzymes are the body's main defense against cancer and can be used as a cancer treatment. His methods have been generally rejected by the medical community. and he has been characterized as a quack and fraud by other doctors and health fraud watchdog groups. In 1994 Gonzalez was reprimanded and placed on two years' probation by the New York state medical board for "departing from accepted practice".
The Oasis of Hope Hospital is a clinic in Tijuana, Mexico providing alternative cancer treatments to its customers. The clinic was founded by the physician Ernesto Contreras. After his death in 2003, the management of the hospital was taken over by his son, Francisco Contreras, and nephew, Daniel Kennedy.
Grape therapy, also known as ampelotherapy, is a form of naturopathic alternative medicine that involves heavy consumption of grapes, including seeds, and parts of the vine, including leaves. The concept has no scientific basis and is widely regarded as quackery.
Jessica Ainscough was an Australian teen magazine editor who became a writer and wellness entrepreneur following a rare cancer diagnosis at the age of 22 years. Ainscough went by the self-coined nickname "The Wellness Warrior" and used her popular blog by the same name to share her personal story of using alternative cancer treatments. Ainscough died of her untreated cancer at the age of 29.
Anthony J. Sattilaro (1931-1989) was an American physician and promoter of macrobiotics as a cancer cure.
Kefford is particularly concerned about cancer patients persuaded to undergo the much-hyped U.S. Gerson diet program, which involves the use of ground coffee enemas, which can cause colitis (inflammation of the bowel), fluid and electrolyte imbalances, and in some cases septicaemia. The U.S. Food and Drug Administration has warned against this regime, which is known to have caused at least three deaths.
