Normal PSA levels differ by age. For men under 50, a PSA level up to 2 ng/mL is considered normal, whereas for men aged 50-59, up to 3 ng/mL is said to be normal.

PSA test results after age 65 provide key information on men’s risk for metastatic prostate cancer and cancer death, study findings suggest.

A new urine test could help men with an elevated PSA, or prostate specific antigen, level avoid unnecessary biopsies and MRIs. The test screens for 18 genetic markers in the urine that are highly ...
