What is a normal blood PSA?
A normal PSA level is considered to be 4.0 nanograms per milliliter (ng/mL) of blood, but this varies by age: For men in their 50s or younger, a PSA level should be below 2.5 in most cases. Older men often have slightly higher PSA levels than younger men.

Why is PSA testing controversial?
The shift comes on the heels of a growing body of evidence that shows the benefits of PSA screening may not outweigh the potential harm of unnecessary treatment. PSA screening has always been somewhat controversial. That’s because PSA tests often alert doctors to the presence of cancer, but there is no precise way to determine, definitively, whether the cancers detected would have ever caused symptoms or harm during a man’s lifetime.
