(攝護腺) 前列腺癌篩 PSA (男)
Prostate-Specific Antigen (PSA)
*Prostate-specific antigen (PSA) is a protein secreted by prostate cells, primarily found in the blood. PSA testing is mainly used for screening and monitoring prostate cancer.
*Normal Range
General adult male: < 4.0 ng/mL (Range may vary with age and individual differences)
*Risks Associated with Elevated PSA Levels
-Prostate Cancer:
Elevated PSA levels may indicate the presence of prostate cancer. However, not all elevated PSA levels indicate cancer, as benign prostate conditions like benign prostatic hyperplasia (BPH) or prostatitis can also cause an increase in PSA.
-Benign Prostatic Conditions:
Benign prostatic hyperplasia (BPH) and prostatitis (inflammation of the prostate) are non-cancerous conditions that can also raise PSA levels.
-Infections or Post-Surgery:
Urinary tract infections, prostate massage, or recent surgeries (such as prostate surgery) may cause a temporary increase in PSA levels.
*Health Recommendations
-Regular Screening:
Men, especially those over the age of 50 or with a family history of prostate cancer, are advised to undergo regular PSA screening.
-Further Investigation:
If PSA levels are elevated, further testing such as prostate ultrasound or biopsy is needed to determine whether prostate cancer is present.
*Conclusion
PSA is an important tool for prostate cancer screening. Although it has value for screening, an elevated PSA level does not necessarily indicate cancer. It should be combined with other diagnostic tests for a comprehensive assessment.
