Since symptoms often can’t be relied upon, screening focuses on identifying higher-risk groups and monitoring them more closely — specifically Black men, men over 55, and men with a strong family history of prostate cancer. For these groups, the PSA blood test is the primary screening tool used. It isn’t perfect: it can miss cancers, and it can also flag an elevated result when cancer isn’t actually present, leading to unnecessary anxiety and follow-up testing. Symptoms remain the backup system — if something changes, that’s the signal to see a doctor.
Why “No Symptoms” Doesn’t Always Mean Danger, Either
Interestingly, autopsy studies of older men have found that up to half had prostate cancer they were never aware of, and it never caused them harm — earning prostate cancer the description “the cancer you die with, not the cancer you die from” in many cases. The more aggressive prostate cancers do tend to grow faster and are more likely to eventually cause noticeable symptoms. Still, PSA testing’s imperfections — missing real cancers while also flagging some that would never have caused harm — are a genuine, acknowledged limitation of current screening, which is part of why researchers continue working on more accurate tests.
The Bottom Line
Awareness alone isn’t enough, because prostate cancer doesn’t wait for an awareness campaign to develop. Know your personal risk factors, understand that no symptoms doesn’t guarantee no disease, and don’t ignore bone pain, blood in urine or semen, new erectile dysfunction, or urinary changes — even though most of these have more common, less serious explanations. If you’re in a higher-risk group, talk to your doctor about whether and when PSA screening makes sense for you.
