Not the norm at all if you're over 70, according to the American Cancer Association guidelines. For men 50-69 it is a different story.
It's data-driven. PSA levels for those over 70 have dubious predictive benefits, as established in multiple studies that have cited multiple times.
If test A tells patient type 1 that he has condition B with high certainty (say >75%), then the test is probably awesome for patient type 1.
If test A tells patient type 2 with only 50% certainty he has condition B, with high numbers of both false positives and false negatives, then the test is of little value for patient type 2.
Doctors can go against the guidelines when the patient is on board, but it's silly to argue that going with established guidelines is somehow outside the norms of good medical practice.
