Cancer seems to take a disproportionate number of broadcast hosts: Rush, Matt Patrick, Jay Severin, Tony Snow...
Observational bias!
In actual fact, cancer takes a disproportionate number of 1) airplane pilots (due to UV exposure); 2) lifeguards (UV); 3) desk jobs (sitting); 4) nail salon workers (fumes); farmers / agricultural workers (exposure to pesticides); 5) firefighters (smoke inhalation).
Though I do suppose that radio hosts do sit a lot.
