It also sounds like he didn't go to the doctor from 2003 to 2011. Either he had an extremely virulent prostate cancer (which is often the case if you get prostate cancer before 50), or he carried it a long time, and a normal physical would have caught it years earlier, when he would have had a chance at cure or long-term survival.
Would he have even gone to the doctor every year or two if he was insured? Maybe.
