PSA is organ-specific, meaning it comes only from the prostate, but it is not cancer-specific. Several conditions can raise PSA, and recognizing them helps guide the right workup.
- Benign prostatic hyperplasia (BPH): Age-related enlargement of the prostate is the most common reason for a slowly rising PSA in men over 50. Learn more on our enlarged prostate page.
- Prostatitis: Inflammation or infection of the prostate can cause sharp PSA spikes. Treatment of the underlying inflammation often returns PSA to baseline.
- Urinary tract infection (UTI): Active bacterial UTI can temporarily elevate PSA. We typically retest 4-6 weeks after treatment.
- Recent ejaculation or cycling: Ejaculation within 48 hours and prolonged bike riding can transiently raise PSA. Repeat testing under controlled conditions is often clarifying.
- Procedures and catheters: Cystoscopy, prostate biopsy, and recent urethral catheterization can elevate PSA for several weeks.
- Prostate cancer: A persistent unexplained elevation, especially with a rising trend or abnormal exam, raises the suspicion for cancer and warrants further workup.
According to the American Cancer Society, most men with a mildly elevated PSA do not have prostate cancer. Distinguishing benign from concerning patterns is exactly what a urologist does best.
