It's interesting how those of us who have had the disease seem to understand the role of PSA better even than its inventor. There seems to be a common misunderstaning among these articles: that a man gets an automatic PSA test, and if it's over 4 they are subject to needless treatment that can ruin their quality of life. I can understand the average person on the street falling for this misconception but experts such as the one in the article know better. And even if they don't explicitely state the misconception, they certainly fan those same flames.
In reality, as we know, PSA is only an early indicator that something may be going on that needs to be checked out. It may be PC, but more likely it's an infection, BPH, or nothing at all -- maybe just riding a bike or having sex just before the test. A repeat high PSA, especially a higher one, might indicate the need for a biopsy. And this about a "painful" biiopsy, especially coming from a doctor, is alarmist and utrue. Sure, there are painful biopsies, just as there are painful tooth fillings. But no one would argue that a filling is painful therefore don't have one if you need it. I didn't feel a thing during my biopsy. My uro game me a shot and, other than a tiny twinge from the needle, no more than when getting a flu shot, I felt nothing. If there is a problem with paiful biopsies, I'm sure medical science can fix that very easily.
Even after a biopsy, no treatment may be needed. It might be negative, or it might show cancer at such an early stage that watchful waiting is appropriate.
It's only for cancers that are aggressive, or could turn aggressive, that action is needed. Can they tell us which are which? Not perfectly but, without PSA to kick start the process, we can be sure that every cancer they found would be aggressive, because it would be found at such a late stage that it would be giving us symptoms.
So I don't understand what is driving all these PSA articles lately, but I'm glad a routine PSA test started a process that found multiple cancers in my prostate that would have escaped within another few months. I feel sad for all of those men who will be scared away from PSA testing by these articles.
