Researcher: Every year approximately the same number of people die of iatrogenic "disease" -- that is, as a direct result of medical treatments or hospitalization -- as die of all other causes combined. Ttherefore, if medicine could find ways of preventing all iatrogenic disease, the number of deaths per year would decrease by half. The reasoning in the researcher's argument is flawed because the argument fails to consider that ['people who do not die of one cause may soon die of another cause', 'prevention of noniatrogenic disease will have an effect on the occurrence of iatrogenic disease', 'some medical treatments can be replaced by less invasive or damaging alternatives', 'there is no one way to prevent all cases of death from iatrogenic disease']
