A massive scar on John Nolan's back from where his lung was removed this year after being diagnosed with mesothelioma, a cancer that is only caused by exposure to asbestos. John is seen at his home in Stevensville, Ontario. Now aged 67, John was exposed to asbestos while a renovation was being done beside his office at a building in Windsor, Ontario in the 1980's.
