Re: Death rate from prostate cancer

But has the DIAGNOSING rate for PC been steady over the timeframe that would have allowed for a stat survey (presumably retrospective) of an actuall cohort of patients?

To me it seams very believable if you looked at a sample of patients diagnosed with PC is 1970 (for example), you would find 30% died of PC. With a low level of screening, you obviously would have a much higher percentage of advanced cancers.

You really can't come much more recently than this for a sample period w/o having too many patients live through the study period.

So, David could be "right" in a formal kind of way, while the best guess for the "current" rate would be much lower.
