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.
Alternative cancer treatments are typically contrasted with
Since the late 19th century, medical researchers have established modern cancer care through the
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 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
Alternative treatments, by contrast, are used in place of mainstream treatments. The most popular alternative cancer therapies include restrictive
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.
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.
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
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]

Areas of research
Specific methods
- Curcumin is a component of turmeric. It is under preliminary research for therapeutic potential but according to Cancer Research UK no reputable organization supports claims that it can "cure" cancer.[34]
- Psilocybin is a psychedelic compound found in more than 100 mushroom species.[35] Three small trials have demonstrated decreased cancer-related psychiatric distress, including anxiety and depression with its use.[35]
- HuaChanSu, traditional Chinese medicine derived from the parotoid gland secretion of toads of the genus Bufo.[36][37]
- Medical cannabis (for "appetite stimulation" and "pain")[38][39]
- Selenium

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]
- Acupuncture may help with nausea but does not treat the disease.[43] A 2015 Cochrane review found unclear usefulness for cancer pain,[44] though other reviews have found tentative evidence of benefit.[45][46] It is of unclear effect in hot flashes in people with breast cancer.[47]
- The effects of aromatherapy are unclear with no peer-reviewed research in regards to cancer treatment.[48]
- Psychotherapy may reduce anxiety and improve quality of life as well as allow for improving patient moods.[23]
- Massage therapy may temporarily reduce pain.[42]
- There is no evidence that cannabis has a beneficial effect in preventing or treating cancer in humans.[49]
- Hypnosis and meditation may improve the quality of life of cancer patients.[50]
- Music therapy eases cancer-related symptoms by helping with mood disturbances.[23]
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
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
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

This dubious amplification of pseudoscience diminishes trust in the medico-scientific sphere. Cancer misinformation is harmful even when it is not fully embraced or believed, precisely because it creates a lingering impression that no medical consensus exists on the topic or that official sources of information lack credibility.

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'.
