The PSA (Prostate-Specific Antigen) test measures the level of PSA, a protein produced by the prostate gland. This test is primarily used to screen for prostate cancer and to monitor the health of the prostate in men, especially those at higher risk for prostate-related conditions.
Why It’s Important:
- Prostate cancer detection: Elevated PSA levels may indicate prostate cancer, although other factors can also contribute to high PSA levels.
- Monitor prostate health: The PSA test is used to track changes in PSA levels over time, which can help assess the progression of prostate cancer or other prostate conditions like benign prostatic hyperplasia (BPH) or prostatitis.
- Assess treatment effectiveness: For men undergoing treatment for prostate cancer, PSA levels are monitored to evaluate the effectiveness of treatment and check for recurrence.
Factors That Can Affect PSA Levels:
- Prostate Cancer: Elevated PSA is often associated with prostate cancer but is not conclusive on its own.
- Benign Prostatic Hyperplasia (BPH): An enlarged prostate can raise PSA levels without cancer being present.
- Prostatitis: Inflammation of the prostate can also cause elevated PSA levels.
- Age and Ejaculation: PSA levels tend to increase with age and recent ejaculation can temporarily raise PSA levels.
