Prostate-specific antigen: does the current evidence support its use in prostate cancer screening?

Narrative Review

Human

2011 Jul

The study says PSA isn't very good at telling for sure who has early prostate cancer because it often gives wrong signals, leading to too many scary but unnecessary tests. So yes, the claim is right.

Prostate-specific antigen (PSA) levels in serum serve as a biomarker for prostate tissue abnormality, enabling detection of early-stage prostate cancer in asymptomatic individuals when anatomical obstruction has not yet occurred.

New, super-sensitive blood tests can spot tiny amounts of PSA that older tests miss, letting doctors find cancer coming back much sooner—sometimes years before it would have been noticed before.

We need better ways to find the dangerous prostate cancers early, avoid treating harmless ones, and figure out who really needs testing based on their personal risk.

Testing men for prostate cancer with PSA blood tests might save a few lives, but it often finds cancers that would never cause harm, leading to unnecessary treatments with side effects.

Getting tested for prostate cancer with the PSA test finds a lot of slow-growing cancers that would never hurt you—way more than in men who don’t get tested.
