PSA density was calculated as total PSA (ng/ml) divided by prostate volume (ml). Main endpoint was clinically significant cancer (csPCa) defined as Gleason Score ≥ 7.

(PSA) level above 4 ng/mL has historically been recognized as an appropriate threshold to recommend biopsy; however the risk of high-grade disease observed among men with lower PSA levels in the Prostate Cancer Prevention Trial has led to calls to change the criteria for biopsy referral.

At what PSA level should a biopsy be done?

A lower percent-free PSA means that your chance of having prostate cancer is higher and you should probably have a biopsy. Many doctors recommend a prostate biopsy for men whose percent-free PSA is 10% or less, and advise that men consider a biopsy if it is between 10% and 25%.

What is an extremely high PSA level?

PSA levels under 4 ng/ml are generally considered normal, while levels over 4 ng/ml are considered abnormal. PSA levels between 4 and 10 ng/ml indicate a risk of prostate cancer higher than normal. When the PSA level is above 10 ng/ml, risk of prostate cancer is much higher.
