GP offered me a PSA test at 58, I feel completely fine, and now I can't decide whether to open this box at all. What did you do?

Went in for the boring annual bloods (the ones I've been rationing down for a couple of years after learning my lesson on this board) and the GP asked, almost in passing, whether I wanted a PSA test added while she was at it. Prostate check. I'm 58, no symptoms, nothing wrong that I can point to, dad's still going strong at 84 with a prostate that's never bothered anyone.

And I froze. Because my instinct after everything I've read here is "no unnecessary tests", but this one has the word CANCER attached and that changes the maths in my head in a way I don't fully trust. She was very fair about it, said it's genuinely my call, gave me a leaflet, told me to think about it and come back.

So here's my problem. I can't tell if declining it is the sensible risk-based discipline I've been trying to learn, or if it's the one time being a tightwad about tests actually bites me. How do you even decide something like this when you feel completely fine? What did the rest of you do when you got asked?

Got asked the same at 46 and said no, but honestly mostly because I didn't understand the question and "no" felt safer than looking clueless. Which is a terrible reason. Following this because I clearly should have an actual basis for it.

The thing that unlocked it for me (asked at 55, ended up saying not yet) was realising the PSA test isn't the decision. The decision is the one AFTER it. A raised number doesn't tell you you've got cancer, it tells you you're now on a conveyor belt of repeat test, then maybe an MRI, then maybe a biopsy, and at the end of it a decent chance of finding a slow thing that was never going to hurt you but which you now can't un-know about.

So the question the leaflet doesn't ask you is: if they find a small cancer that might do nothing for twenty years, do you want to be treated, or watched, or would you rather not have gone looking? I couldn't answer that cleanly, and that told me I wasn't ready to start the test that leads there. Not "never". "Not until I know what I'd do with the answer."

This is the one screening decision I'd never wave anyone away from and never push anyone toward, because it's genuinely balanced in a way most aren't. Let me lay out what actually sits on each side, and then why I think gregor is pointing at the right thing.

The band first, because it matters: PSA testing is framed by the major evidence bodies as a shared decision, roughly ages 55 to 69, offered selectively rather than recommended for everyone. At 58 you're squarely inside it, which is precisely why your GP asked instead of just booking it. From about 70 it's generally advised against, because the harms outgrow the shrinking benefit.

The benefit, stated honestly with the numbers: the biggest trial found screening prevented around 1 prostate cancer death for every 1000 men invited, over about 13 years. That's a real life saved and also a smaller number than the word "cancer screening" makes most of us picture. On the other side, a meaningful share of the cancers screening finds, by some estimates somewhere between 20 and 50 percent, are the kind that would never have caused symptoms in your lifetime. But once one's found, it's hard to know which kind it is, so men get treated, and prostate treatment carries real risks of incontinence and sexual side effects. That's the trade in one paragraph.

dgb, your instinct and your fear are both correct, they're just weighing different things. The discipline you've learned is right that most add-on tests generate worry faster than benefit. The word CANCER is right that this isn't a speculative neck ultrasound, it's a test with a genuine, if modest, mortality benefit behind it. Which is exactly why it's a decision and not a rule. The question I'd sit with is the one gregor named: if a small, slow cancer turned up, what would you want to do about it? Your answer to that should drive whether you test, because the test only makes sense if you've got a plan for what it might find. I wrote the long version of all this up in the PSA testing and prostate cancer screening guide, and the broader logic of who cancer screening actually helps is in the cancer screening overview. But the piece I can't supply from here is your history and your values, and those belong in the room with your GP, who's already handed you exactly the right kind of "it's your call".

Worth adding one practical thing, because it nearly tripped me: if you do go for it, don't cycle hard the day before and don't book it the morning after, ahem, activity. Both can bump PSA up for benign reasons and hand you a false alarm you'll then spend three weeks chasing. My GP mentioned it almost as an afterthought and I'd have got it wrong otherwise.

Closing the loop. Went back, had the actual conversation instead of the leaflet, and the deciding question turned out to be the one you all pushed me toward: what would I do if they found a small slow one. Sat with it for a fortnight and my honest answer was that at 58, with no symptoms and no family history, I'd want to know and I'd rather have the option early than not. So for ME, this time, the answer was yes, and I've booked it.

Which is the funny part: same disciplined process I've used to decline half a dozen add-ons landed on a yes here, and I trust the yes precisely because it wasn't automatic. Whatever the number says, I know why I'm taking the test, and I know what I'd do with the answer. Thanks all, this board remains better than the leaflets.
