Alternative cancer treatment describes any cancer treatment or practice that is not part of the conventional standard of cancer care. [2] 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 and many have been described as fundamentally pseudoscientific. [3] [4] [5] [6] Concerns have been raised about the safety of some purported treatments and some have been found unsafe in clinical trials. Despite this, many untested and disproven treatments are used around the world.

Contents

Alternative cancer treatments are typically contrasted with experimental cancer treatments  – science-based treatment methods – and complementary treatments, which are non-invasive practices used in combination with conventional treatment. All approved chemotherapy medications were considered experimental treatments before completing safety and efficacy testing.[ citation needed ]

Since the late 19th century, medical researchers have established modern cancer care through the development of chemotherapy, radiation therapy, targeted therapies, and refined surgical techniques. As of 2019, only 32.9% of cancer patients in the United States died within five years of their diagnosis. [7] Despite their effectiveness, many conventional treatments are accompanied by a wide range of side effects, including pain, fatigue, and nausea. [8] [9] Some side effects can even be life-threatening.[ citation needed ] Many supporters of alternative treatments claim increased effectiveness and decreased side effects when compared to conventional treatments. However, one retrospective cohort study showed that patients using alternative treatments instead of conventional treatments were 2.5 times more likely to die within five years. [10]

Most alternative cancer treatments have not been tested in proper clinical trials. Among studies that have been published, the quality is often poor. A 2006 review of 196 clinical trials that studied unconventional cancer treatments found a lack of early-phase testing, little rationale for dosing regimens, and poor statistical analyses. [11] These kinds of treatments have appeared and vanished throughout history. [12]

Terminology

Complementary and alternative cancer treatments are often grouped together, in part because of the adoption of the phrase complementary and alternative medicine by the United States Congress. [13] The World Health Organization uses the phrase traditional, complementary, and integrative medicine (TCIM) to describe a similar set of treatments. [14]

Complementary treatments are used in conjunction with proven mainstream treatments. They tend to be pleasant for the patient, not involve substances with any pharmacological effects, inexpensive, and intended to treat side effects rather than to kill cancer cells. [15] Medical massage and self-hypnosis to treat pain are examples of complementary treatments.

About half the practitioners who dispense complementary treatments are physicians, although they tend to be generalists rather than oncologists. [12] As many as 60% of American physicians have referred their patients to a complementary practitioner for some purpose. [12] While conventional physicians should always be kept aware of any complementary treatments used by a patient, many physicians in the United Kingdom are at least tolerant of their use, and some might recommend them. [16]

Alternative treatments, by contrast, are used in place of mainstream treatments. The most popular alternative cancer therapies include restrictive diets, mind-body interventions, bioelectromagnetics, nutritional supplements, and herbs. [12] The popularity and prevalence of different treatments varies widely by region. [17] Cancer Research UK warns that alternative treatments may interact with conventional treatment, may increase the side effects of medication, and can give people false hope. [16]

Prevalence

Survey data about how many cancer patients use alternative or complementary therapies vary from nation to nation as well as from region to region. Reliance on alternative therapies is common in developing countries, because people cannot afford effective medical treatment. [14] For example, in Latin America, most cancer patients have used natural products, nutritional supplements, and spiritual practices (such as praying) in addition to, or instead of, medical care. [14] In Africa, where millions of people do not have financial or geographical access to an oncologist, many Africans with cancer rely on traditional African medicine, which uses divination, spiritualism, and herbal medicine. [14] About 40% of African cancer patients take herbal preparations. [14] Three-quarters of Chinese people with cancer use some form of Traditional Chinese medicine, especially Chinese herbal preparations. [14] About a third of people with cancer in India use Ayurveda or other elements of AYUSH. [14]

A 2000 study published by the European Journal of Cancer evaluated a sample of 1023 women from a British cancer registry who had breast cancer and found that 22.4% had consulted with a practitioner of complementary therapies in the previous twelve months. The study concluded that the patients had spent many thousands of pounds on such measures and that use "of practitioners of complementary therapies following diagnosis is a significant and possibly growing phenomenon". [18]

In Australia, one study reported that 46% of children with cancer have been treated with at least one non-traditional therapy. Further 40% of those of any age receiving palliative care had tried at least one such therapy. Some of the most popular alternative cancer treatments were found to be dietary therapies, antioxidants, high dose vitamins, and herbal therapies. [19]

In the United States, nearly all adults who use non-conventional medical therapies do so in addition to conventional medical treatment, rather than as an alternative to it. [20] Use of unconventional cancer treatments in the United States has been influenced by[ citation needed ] the U.S. federal government's National Center for Complementary and Alternative Medicine (NCCAM), initially known as the Office of Alternative Medicine (OAM), which was established in 1992 as a National Institutes of Health (NIH) adjunct by the U.S. Congress. More specifically, the NIC's Office of Cancer Complementary and Alternative Medicine sponsors over $105 million a year in grants for pseudoscientific cancer research.[ citation needed ] Over thirty American medical schools have offered general courses in alternative medicine, including the Georgetown, Columbia, and Harvard university systems, among others. [12]

People who choose alternative treatments

People who are drawn to alternative treatments tend to believe that evidence-based medicine is extremely invasive or ineffective, while still hoping that their own health could be improved. [21] They are loyal to their alternative healthcare providers and believe that "treatment should concentrate on the whole person". [21] Among people who (correctly or incorrectly) believe their condition is untreatable, "desperation drives them into the hands of anyone with a promise and a smile." [22] Con artists have long exploited patients' perceived lack of options to extract payments for ineffectual and even harmful treatments. [22]

No evidence suggests that the use of alternative treatments improves survival. [23] In 2017, one retrospective, observational study suggested that people who chose alternative medicine instead of conventional treatments were more than twice as likely to die within five years of diagnosis. [10] Breast cancer patients choosing alternative medicine were 5.68 times more likely to die within five years of diagnosis. [10]

Although they are more likely to die than non-users, some users of alternative treatments feel a greater sense of control over their destinies and report less anxiety and depression. [24] They are more likely to engage in benefit finding, which is the psychological process of adapting to a traumatic situation and deciding that the trauma was valuable, usually because of perceived personal and spiritual growth during the crisis. [25]

In a survey of American cancer patients, baby boomers were more likely to support complementary and alternative treatments than people from an older generation. [26] White, female, college-educated patients who had been diagnosed more than a year ago were more likely than others to report a favorable impression of at least some complementary and alternative benefits. [26]

Unproven and disproven treatments

Many therapies without evidence have been promoted to treat or prevent cancer in humans. In many cases, evidence suggests that the treatments do not work. Unlike accepted cancer treatments, unproven and disproven treatments are generally ignored or avoided by the medical community. [3]

Despite this, many of these therapies have continued to be promoted as effective, particularly by promoters of alternative medicine. Scientists consider this practice quackery, [27] [28] and some of those engaged in it have been investigated and prosecuted by public health regulators such as the US Federal Trade Commission, [29] the Mexican Secretariat of Health [30] and the Canadian Competition Bureau. In the United Kingdom, the Cancer Act makes the unauthorized promotion of cancer treatments a criminal offense. [31] [32]

In 2008, the United States Federal Trade Commission acted against some companies that made unsupported claims that their products, some of which included highly toxic chemicals, could cure cancer. Targets included Omega Supply, Native Essence Herb Company, Daniel Chapter One, Gemtronics, Inc., Herbs for Cancer, Nu-Gen Nutrition, Inc., Westberry Enterprises, Inc., Jim Clark's All Natural Cancer Therapy, Bioque Technologies, Cleansing Time Pro, and Premium-essiac-tea-4less. [33]

Areas of research

Specific methods

Pain relief

Most studies of complementary and alternative medicine in the treatment of cancer pain are of low quality in terms of scientific evidence. Studies of massage therapy have produced mixed results, but overall show some temporary benefit for reducing pain, anxiety, and depression and a very low risk of harm, unless the patient is at risk for bleeding disorders. [40] [41] There is weak evidence for a modest benefit from hypnosis, supportive psychotherapy and cognitive therapy. Results about Reiki and touch therapy were inconclusive. The most studied such treatment, acupuncture, has demonstrated no benefit as an adjunct analgesic in cancer pain. The evidence for music therapy is equivocal, and some herbal interventions such as PC-SPES, mistletoe, and saw palmetto are known to be toxic to some cancer patients. The most promising evidence, though still weak, is for mind–body interventions such as biofeedback and relaxation techniques. [42]

Examples of complementary therapy

As stated in the scientific literature, the measures listed below are defined as 'complementary' because they are applied in conjunction with mainstream anti-cancer measures such as chemotherapy, in contrast to the ineffective therapies viewed as 'alternative' since they are offered as substitutes for mainstream measures. [12]

Alternative theories of cancer

Some alternative cancer treatments are based on unproven or disproven theories of how cancer begins or is sustained in the body. Some common concepts are:

Mind-body connection

This idea says that cancer progression is related to a person's mental and emotional state. Treatments based on this idea are mind–body interventions. Proponents say that cancer forms because the person is unhappy or stressed, or that a positive attitude can cure cancer after it has formed. A typical claim is that stress, anger, fear, or sadness depresses the immune system, whereas that love, forgiveness, confidence, and happiness cause the immune system to improve, and that this improved immune system will destroy the cancer. This belief that generally boosting the immune system's activity will kill the cancer cells is not supported by any scientific research. [51] In fact, many cancers require the support of an active immune system (especially through inflammation) to establish the tumor microenvironment necessary for a tumor to grow. [52]

Toxin theory of cancer

In this idea, the body's metabolic processes are overwhelmed by normal, everyday byproducts. These byproducts, called "toxins", are said to build up in the cells and cause cancer and other diseases through a process sometimes called autointoxication or autotoxemia. Treatments following this approach are usually aimed at detoxification or body cleansing, such as enemas.

Low activity by the immune system

This claim asserts that if only the body's immune system were strong enough, it would kill the "invading" or "foreign" cancer. Unfortunately, most cancer cells retain normal cell characteristics, making them appear to the immune system to be a normal part of the body. Cancerous tumors also actively induce immune tolerance, which prevents the immune system from attacking them. [51]

Epigenetic disregulation

This claim uses research into the mechanism of epigenetics to understand how mutations in the epigenetic machinery of cells will altered histone acetylation patterns to create cancer epigenetics. DNA damage appears to be the primary underlying cause of cancer. [53] [54] If DNA repair is deficient, DNA damage tends to accumulate. Such excess DNA damage can increase mutational errors during DNA replication due to error-prone translesion synthesis. Excess DNA damage can also increase epigenetic alterations due to errors during DNA repair. Such mutations and epigenetic alterations can give rise to cancer.[ citation needed ]

Acupuncture is a form of alternative medicine and a component of traditional Chinese medicine (TCM) in which thin needles are inserted into the body. Acupuncture is a pseudoscience; the theories and practices of TCM are not based on scientific knowledge, and it has been characterized as quackery.

Alternative medicine is any practice that aims to achieve the healing effects of medicine despite lacking biological plausibility, testability, repeatability or evidence of effectiveness. Unlike modern medicine, which employs the scientific method to test plausible therapies by way of responsible and ethical clinical trials, producing repeatable evidence of either effect or of no effect, alternative therapies reside outside of mainstream medicine and do not originate from using the scientific method, but instead rely on testimonials, anecdotes, religion, tradition, superstition, belief in supernatural "energies", pseudoscience, errors in reasoning, propaganda, fraud, or other unscientific sources. Frequently used terms for relevant practices are New Age medicine, pseudo-medicine, unorthodox medicine, holistic medicine, fringe medicine, and unconventional medicine, with little distinction from quackery.

<span class="mw-page-title-main">Acupressure</span> Alternative medicine technique similar to acupuncture

Acupressure is an alternative medicine technique often used in conjunction with acupuncture or reflexology. It is based on the concept of life energy, which flows through "meridians" in the body. In treatment, physical pressure is applied to acupuncture points, or ashi trigger points, with the aim of clearing blockages in these meridians. Pressure may be applied by hand, by elbow, or with various devices.

<span class="mw-page-title-main">Quackery</span> Promotion of fraudulent or ignorant medical practices

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 at markets by shouting to gain attention.

Apitherapy is a branch of alternative medicine that uses honey bee products, including honey, pollen, propolis, royal jelly and bee venom. There has been no scientific or clinical evidence for the efficacy or safety of apitherapy treatments.

<span class="mw-page-title-main">Pain management</span> Interdisciplinary approach for easing pain

Pain management is an aspect of medicine and health care involving relief of pain in various dimensions, from acute and simple to chronic and challenging. Most physicians and other health professionals provide some pain control in the normal course of their practice, and for the more complex instances of pain, they also call on additional help from a specific medical specialty devoted to pain, which is called pain medicine.

<span class="mw-page-title-main">Auriculotherapy</span> Pseudoscientific ear stimulation treatment

Auriculotherapy is a form of alternative medicine based on the idea that the ear is a micro system and an external organ, which reflects the entire body, represented on the auricle, the outer portion of the ear. Conditions affecting the physical, mental or emotional health of the patient are assumed to be treatable by stimulation of the surface of the ear exclusively. Similar mappings are used by several modalities, including the practices of reflexology and iridology. These mappings are not based on or supported by any medical or scientific evidence, and are therefore considered to be pseudoscience.

<span class="mw-page-title-main">Ozone therapy</span> Unproven alternative medicine

Ozone therapy is an alternative medical treatment that introduces ozone or ozonides to the body. The United States Food and Drug Administration (FDA) prohibits all medical uses of ozone "in any medical condition for which there is no proof of safety and effectiveness", stating "ozone is a toxic gas with no known useful medical application in specific, adjunctive, or preventive therapy. In order for ozone to be effective as a germicide, it must be present in a concentration far greater than that which can be safely tolerated by man and animals."

<span class="mw-page-title-main">Craniosacral therapy</span> Pseudoscientific alternative medicine technique

Craniosacral therapy (CST) or cranial osteopathy is a form of alternative medicine that uses gentle touch to feel non-existent rhythmic movements of the skull's bones and supposedly adjust the immovable joints of the skull to achieve a therapeutic result. CST is a pseudoscience and its practice has been characterized as quackery. It is based on fundamental misconceptions about the anatomy and physiology of the human skull and is promoted as a cure-all for a variety of health conditions.

Anthroposophic medicine is a form of alternative medicine based on pseudoscientific and occult notions. Devised in the 1920s by Rudolf Steiner (1861–1925) in conjunction with Ita Wegman (1876–1943), anthroposophical medicine draws on Steiner's spiritual philosophy, which he called anthroposophy. Practitioners employ a variety of treatment techniques based upon anthroposophic precepts, including massage, exercise, counselling, and substances.

<span class="mw-page-title-main">Energy medicine</span> Pseudo-scientific alternative medicine

Energy medicine is a branch of alternative medicine based on a pseudo-scientific belief that healers can channel "healing energy" into a patient and effect positive results. The field is defined by shared beliefs and practices relating to mysticism and esotericism in the wider alternative medicine sphere rather than any sort of unified terminology, leading to terms such as energy healing or vibrational medicine being used as synonymous or alternative names. In most cases there is no empirically measurable energy involved: the term refers instead to so-called subtle energy. Practitioners may classify the practice as hands-on, hands-off, and distant where the patient and healer are in different locations. Many schools of energy healing exist using many names: for example, biofield energy healing, spiritual healing, contact healing, distant healing, therapeutic touch, Reiki or Qigong.

Alternative veterinary medicine is the use of alternative medicine in the treatment of animals. Types alternative therapies used for veterinary treatments may include, but are not limited to, acupuncture, herbal medicine, homeopathy, ethnomedicine and chiropractic. The term includes many treatments that do not have enough evidence to support them being a standard method within many veterinary practices.

Cancer treatments are a wide range of treatments available for the many different types of cancer, with each cancer type needing its own specific treatment. Treatments can include surgery, chemotherapy, radiation therapy, hormonal therapy, targeted therapy including small-molecule drugs or monoclonal antibodies, and PARP inhibitors such as olaparib. Other therapies include hyperthermia, immunotherapy, photodynamic therapy, and stem-cell therapy. Most commonly cancer treatment involves a series of separate therapies such as chemotherapy before surgery. Angiogenesis inhibitors are sometimes used to enhance the effects of immunotherapies.

<span class="mw-page-title-main">Virginia Livingston</span> American physician

Virginia Livingston (1906–1990) was an American physician and cancer researcher who advocated the unsupported theory that a specific species of bacteria she named Progenitor cryptocides was the primary cause of cancer in humans. Her theories about P. cryptocides have not been duplicated by researchers, and a clinical trial of her therapy did not show any efficacy in the treatment of cancer. The American Cancer Society, which did not support Livingston's treatment protocol for cancer, categorically denied her theory of cancer origins.

Blood irradiation therapy is an alternative medical procedure in which the blood is exposed to low-level light for therapeutic reasons. The practice was originally developed in the United States, but most recent research on it has been conducted in Germany and in Russia. Low-level laser therapy has been tested for a wide range of conditions, but rigorous double-blinded studies have not yet been performed. Furthermore, it has been claimed that ultraviolet irradiation of blood kills bacteria by DNA damage and also activation of the immune system. Blood irradiation therapy is highly controversial, and has fallen from mainstream use since its heyday in the 1940s and 1950s.

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.

Alternative medicine describes any practice which aims to achieve the healing effects of medicine, but which lacks biological plausibility and is untested or untestable. Complementary medicine (CM), complementary and alternative medicine (CAM), integrated medicine or integrative medicine (IM), and holistic medicine are among many rebrandings of the same phenomenon.

Alternative cancer cures (ACCs) typically have a common life cycle (Ernst, 2000). At the origin of almost every ACC is a charismatic individual who claims to have found the answer to cancer. He (the male sex seems to dominate) often supports his claims with pseudoscientific evidence referring to (but rarely presenting) many cured patients. Thus he soon gathers ardent supporters who lobby for a wider acceptance of this ACC. The pressure on the medical establishment increases to a point where the treatment is finally submitted to adequate testing. When the results turn out to be negative, the ACC's proponents argue that the investigations were not done properly. In fact, they were set up to generate a negative result so that the commercial interests of orthodoxy would not be threatened. A conspiracy theory is thus born, and the ACC lives on in the 'alternative underground'.
