"""My grandfather. WWII Navy Veteran.
As a Navy man and an Power & Light employee he was exposed to asbestos.
He was exposed to radiation in Nagasaki 15 day after we nuked it, when he picked up the POW's to bring them home.
He also smoked for years in his younger days. Although he did quit 30 or so years before his death.
All could be contributing factors to his cancer."""
Steve McQueen also smoked for years, yet the good doctors blamed his lung cancer on asbestos exposure.
I bet you that that today no doctor would blame lung cancer on anything BUT smoking if the patient ever lit up a cigarette or was exposed to second hand smoke for longer then two weeks during his lifetime.
Actually asbestos exposure trumps smoking. I worked in a law firm that defended an asbestos company, I know.
