ORIGINAL: velvetears If this were true - wouldn't prostitutes have a high rate of this kind of cancer? Do they? Perhaps, but to survey that population, you'd have to give them incentive to participate, get a randomized sample, and so forth. It'd also have to be legal in that country, which is often not the case. Another major obstacle is that you would want a control population that had the same lifestyle components, but not the oral sex, which would mean finding a statistically meaningful number of prostitutes who are demographically representative and do not provide oral sex. In short, the "research materials" are unobtainium. Plus, there's the whole bit about it being considered unethical to do research on stuff that is suspected to be harmful, in most cases. The docs can research themselves, though.
