Bioresonance therapy – diagnosis and therapy delivered by attaching an electrical device to the patient, on the basis that cancer cells emit certain electromagnetic oscillations. The Memorial Sloan Kettering Cancer Center says that such claims are not supported by any evidence and note that the US Food and Drug Administration has prosecuted many sellers of such devices.
Electrohomeopathy (or Mattei cancer cure) – a treatment devised by Count Cesare Mattei (1809–1896), who proposed that different "colors" of electricity could be used to treat cancer. Popular in the late nineteenth century, electrohomeopathy has been described as "utter idiocy".
Electro Physiological Feedback Xrroid – an electronic device promoted as being capable of diagnosing and treating cancer and a host of other ailments. However, according to Quackwatch: "The Quantum Xrroid device is claimed to balance 'bio-energetic' forces that the scientific community does not recognize as real. It mainly reflects skin resistance (how easily low-voltage electric currents from the device pass through the skin), which is not related to the body's health."
Light therapy – the use of light to treat medical conditions. According to the American Cancer Society, alternative approaches – such as chromotherapy or the use of light boxes – have not been shown to be effective for cancer treatment.
Magnetic therapy – the practice of placing magnets on and around the body in order to treat illness. Although this has been promoted as a treatment for cancer and other diseases, the American Cancer Society says, "available scientific evidence does not support these claims".
Orgone – a type of life force proposed to exist by Wilhelm Reich (1897–1957) which he claimed could be harnessed to cure diseases, including cancer, perhaps by sitting inside an "orgone accumulator" – a cupboard-like box with metal and organic linings. Quackwatch comments that scientists investigating Reich's ideas have been "unable to find the slightest evidence in Reich's data or elsewhere that such a thing as orgone exists".
Polarity therapy – a type of energy medicine based on the idea that the positive or negative charge of a person's electromagnetic field affects their health. Although it is promoted as effective for curing a number of human ailments, including cancer, the American Cancer Society says "available scientific evidence does not support claims that polarity therapy is effective in treating cancer or any other disease".
Rife Frequency Generator – an electronic device purported to cure cancer by transmitting radio waves. Cancer Research UK state, "there is no evidence to show that the Rife machine does what its supporters say it does".
Therapeutic Touch (or TT) – contrary to its name, a technique that does not usually involve touching; rather, a practitioner holds their hands close to a patient to affect the "energy" in their body. According to the American Cancer Society, "available scientific evidence does not support any claims that TT can cure cancer or other diseases".
Zoetron therapy – therapy based around a large electromagnetic device that emitted a weak field which, it was claimed, could kill cancer cells. Patients were charged US$15,000 up-front for treatment in Mexican clinics. In 2005 criminal charges were brought against the owners of the company making the device for their claims of its worth. Quackwatch says: "there is no scientific evidence or reason to believe that exposure to weak magnetic fields will kill any cells".
