Prostate Cancer Detection in Men With Serum PSA Concentrations of 2.6 to 4.0 ng/mL and Benign Prostate Examination

Abstract

There is an appreciable rate of detectable prostate cancer in men with serum PSA levels of 2.6 to 4.0 ng/mL. The great majority of cancers detected have the features of medically important tumors. Free serum PSA measurements may reduce the number of additional biopsies required by the lower PSA cutoff.
