Laetrile: A Lesson in Cancer Quackery

The laetrile promotion is not different from previous cancer quackery campaigns, and indeed it represents a classic example of such movements. It differs from its predecessors only in the degree of its success. The laetrile crusade has achieved unprecedented triumph by capitalizing on a unique sociopolitical climate characterized by a growing hostility towards "the establishment," a demand for simple solutions. and frustration with the inability to solve the cancer riddle. It is also directed by sophisticated, radical political machinery. and funded by enormous profits. Nevertheless, as one attempts to assay a historical phenomenon without the advantage of the passage of time, the laetrile movement appears to have peaked and begun its inevitable decline. This is clearly indicated by recent, important judicial decisions. It is also evident that the bandwagon effect on state legislation has waned, and one can be skeptical that many more states will follow in the legalization of laetrile. Not only do the data continue to demonstrate the ineffectiveness of laetrile in animal and human cancers, but the public seems to be more knowledgeable about this fact. More importantly, the campaign to inform the public about the substantial toxicity of lactrile seems to have had some measure of success. Of all the factors, though, it is likely that the unnecessary and inexcusable death of five-year-old Chad Green will be the most important in sounding the death knell of the laetrile movement.
Two final questions should be asked when considering the laetrile phenomenon: Will the promoters of the next great quack cancer remedy be able to learn enough from the lesson of laetrile to improve upon it? Or will we in the medical community have learned enough to squelch it promptly and effectively?
