Wow! If you want to start an argument in polite company, add PSA (prostate specific antigen) screening for prostate cancer to the list of topics (politics & religion) not to be discussed in polite company. And if you want to make yourself unpopular, advocate against PSA screening for prostate cancer as the US Preventive Services Task Force did online yesterday prior to print in July in the Annals of Internal Medicine.
I don't know where you stand on the topic but I suspect that it's colored by whether you're a generalist or a specialist, and whether you've been affected in some manner or not. Not to paint with too broad a brush stroke, but generalists and those who haven't been affected tend to advocate against screening for prostate cancer w/PSA while specialists and those who've been touched tend to recommend mass screening.
