The Claim
PSA screening is associated with a higher rate of overdiagnosis of prostate cancer, as 56.4% of prostate cancers detected in screened men are classified as low-risk tumors unlikely to cause harm, compared to 39.1% in unscreened men.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
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.

1 studyStudy: Towards personalized prostate cancer screening
This study says that PSA tests find lots of slow-growing prostate cancers that would never hurt you — and that happens more often when men get screened, which is exactly what the claim says.
