^^ autopsies are seldom done any more because of CT and MRI -- people rarely die now without knowing what's going on inside them. But old autopsy data showed a remarkably high percentage of elderly men had prostate cancer they never knew about. Prostate cancer that develops after age 65 tends not to be very aggressive. And prostate cancer remains a source of considerable mortality.
