Change in PSA levels over time can help predict aggressive prostate cancer
I think I read years ago that earlier testing - in the mid 40's - was perhaps more useful than a first test in one's 50's, perhaps for the same reason.
I never got around to it then, though, but last night I got the form for some blood tests and PSA is included. The doctor basically said "well, it's the only way we've got of detecting anything", which is true, I guess. He agreed though that it may well result in unnecessary further investigation or treatment.
My impression is Australian doctors are more reluctant to give up testing PSA routinely than are some American doctors. But I could be wrong.
