I initially posted this query in the 'Ask an Expert' section and it was suggested I post over here, so here goes.


An acquaintance is convinced that his cancer has been cured by a device called a 'Rife machine': http://www.spooky2.com/ As far as I can tell from my online searches, there is no recogniseable scientific, reproducible research into the relevant biological responses to electromagnetic stimulation at various frequencies, other than those looking for adverse effects such as those feared in the early days of mobile phone use.


I want to be supportive of him and his new-found enthusiasm, but my concern is that the device is purely a form of placebo generator (it's complicated, it's electronic, and 'the authorities' want to suppress reports of its usefulness). Is anybody aware of a possible mechanism by which this device could, albeit indavertently, provide positive therapeutic effects?
