Generate text that refutes this claim: Although there are many accounts of the efficacy of alternative cancer treatments, not one has been demonstrated to work in a clinical trial  The National Centre for Conventional and Alternative Medicines has spent over $2.5bn on research since 1992. The Dutch government funded research between 1996 and 2003. Alternative therapies have been tested in mainstream medical journals and elsewhere. Not only have thousands of research exercises failed to prove the medical benefit ”alternative” treatments for severe and terminal diseases, serious peer-reviewed studies have routinely disproved them.  It’s all well and good to pick at mistakes in individual studies. Indeed, this tactic often forms the mainstay of pleas for legitimacy made by members of the alternative medical community. However, the odds against such consistently negative results would be extraordinary.  By contrast, conventional medicine only prescribes medicines and treatments that are proven, and vigorously proven, to work.

Partly the problem here may well be that clinical research is simply looking for the wrong things. There is enough anecdotal evidence of success to at least suggest further research – it is worth noting that there’s no money in many of these treatments so they actually get relatively little academic discussion.  A meta-study of the available material on analyses of the effectiveness of complementary medicine by the Cochrane Library found positive or confirmatory outcomes in 34 percent of those papers it reviewed on the subject.  It is also worth reiterating that there is a massive financial interest in ignoring, sidelining or condemning therapies that pose a threat to the medical establishment.  It seems incredibly unlikely that people would come back for more than one dose of a treatment that was having no effect, and yet they do.
