I think PSA can pick it up earlier than that, no?
Not being someone who has the equipment that requires such testing, I'm somewhat limited in my need to know and, therefore, my knowledge. But I do have friends and family of the male persuasion who have been down that road who have spoken about it to me, including my father who died from prostate cancer. I don't think they can definitively diagnose it without a biopsy, which I'm told is not something to be undertaken lightly, and not regularly done, particularly in older people, because prostate cancer grows so slowly.
Just seems to me that if you have a group of people who get regular screenings and a group who doesn't, you can figure out statistically what the value of the screenings might be.
The question on the table was outcomes in country A vs country B, not the value of screenings. Sure, it's easy to compare the post-diagnosis life expectancy of screeners vs non-screeners. (BTW, did you know that getting regular mammograms is not cost effective? The push for them is largely political.)
