Now we're seeing more colon cancer in young people. All of the discussion is around factors that change slowly (diet, alcohol, exercise), no one I've heard has pointed out that a pathogen would explain a quick change.
Have always been fascinated with Paul Ewald's arguments (as laid out in his books The New Germ Theory of Disease and Evolution of Infectious Disease) that most chronic illnesses are due to pathogens.
And yet the only ones listed in detail are the ones in Ukraine, huh.
