Study Notes

Prostate-Specific Antigen (PSA) Testing

  • Serum PSA testing is not recommended as a screening test for prostate cancer due to its limitations.

Indications for PSA Measurement

  • Men should be offered a PSA measurement if they are 50 years or older, or 45 years or older with a family history of prostate cancer.

Elevated PSA Levels

  • If a man's serum PSA level is in excess of 2.5–4ng/mL, clinicians should consider the possibility of prostate cancer and further evaluation may be necessary.

Transrectal Ultrasound Scanning (TRUS) and Biopsies

  • Transrectal ultrasound scanning (TRUS) plus transrectal biopsies should be considered if the PSA level is elevated or if a digital rectal examination is abnormal.

Pre-PSA Test Counseling

  • Men should be informed about the potential risks and benefits of PSA testing, including the risk of false-positive results and the possibility of over-diagnosis and over-treatment, before undergoing a PSA test.
