I believe that county specific studies seem to support your thesis. For instance, countries that eat less processed food (eg Italy) and have stricter rules about pesticides didn't see an increase in stuff like colorectal cancer [1]. Some cancers incidence did grow, but others decreased keeping incidence more or less the same.
