This isn't something that biased scientists just started doing. G. Edward Griffin explains in A World Without Cancer how similar tactics were used to prove that amygdalin (vitamin B17) was an unsuccessful treatment for cancer.

Haven't read that one yet but you should read Goodbye Germ Theory by William Trebing and Murder by Injection by Eustace Mullins, if you haven't.
