While I may be willing to believe that the incidence of cancer in humans could dramatically increase with changes to diet and environment that result from increases in population density, industrialization, pollution, and other factors that are, essentially, caused by human habitation, to me this is a far cry from trumpeting that "cancer is man-made".
Smoking, getting no exercise, and eating lots of saturated fats increases risk factors for coronary heart disease: does this mean that it also is man-made?
What the heck is not man made in this case? Presumably death caused by animal predation? (But then why are you walking around in the predator's catchment area?) Lightning strike? (Why are you walking around in a thunder storm?)
Hrm.
