Prostate-Specific Antigen (PSA) Test: Understanding Its Role in Prostate Health
The Prostate-Specific Antigen (PSA) test is a valuable tool in the early detection and monitoring of prostate health. In this article, we’ll explore what PSA is, its significance in prostate cancer, and how it’s used in clinical practice.
Prostate-Specific Antigen (PSA) is a protein produced by both normal and malignant cells of the prostate gland.
The PSA test measures the level of PSA in the blood Results are reported as nanograms of PSA per millilitre (ng/mL) of blood.

Elevated PSA levels may indicate the presence of prostate cancer.
The FDA originally approved the PSA test in 1986 to monitor the progression of prostate cancer in men already diagnosed with the disease.
In 1994, the PSA test was approved for use alongside a digital rectal exam (DRE) to aid in prostate cancer detection in men aged 50 and older.

Definition: Prostatitis refers to inflammation of the prostate gland.
Cause: It can result from bacterial infection, non-bacterial inflammation, or other factors.
Pain or discomfort in the pelvic area, lower back, or perineum (between the scrotum and anus).
Frequent, urgent, or painful urination.
Fever and chills (if caused by infection).
PSA Impact: Prostatitis can elevate PSA levels due to inflammation but does not necessarily indicate cancer.
Benign Prostatic Hyperplasia (BPH):
Definition: BPH refers to the non-cancerous enlargement of the prostate gland.
Cause: Age-related hormonal changes lead to increased prostate size.
Frequent urination, especially at night.
Difficulty starting or stopping urination.
PSA Impact: BPH can elevate PSA levels due to increased prostate tissue but is not directly linked to cancer.
When PSA levels are elevated, further assessment is necessary.
Doctors consider symptoms, physical examination, and additional tests (such as ultrasound or biopsy) to differentiate benign conditions from cancer.
If a patient has elevated PSA levels without symptoms, doctors may recommend monitoring.
Persistent elevation or concerning symptoms may prompt further investigation.
Remember that while these conditions raise PSA levels, they do not automatically indicate prostate cancer. Consultation with a healthcare provider is crucial for accurate diagnosis and appropriate management.
Screening Recommendations
Routine population screening with the PSA test has become controversial due to both benefits and harms.
Professional medical organisations recommend discussing risks and benefits with doctors before PSA screening.
Some high-risk groups, such as Black men, those with specific genetic variants, and those with a family history of prostate cancer, may start screening earlier.
Screen for prostate cancer before symptoms appear.
Monitor the progression of known conditions.
Assess treatment effectiveness.
After prostate cancer diagnosis, PSA helps determine if cancer has returned after surgery or if treatment is effective.
The PSA test plays a crucial role in prostate health. While it’s not a perfect screening tool, informed discussions with healthcare providers can guide its appropriate use. Regular check-ups and open conversations about prostate health are essential for maintaining overall well-being.
