Prostate-specific antigen (PSA) is a protein produced by the prostate gland. Measuring PSA levels in the blood can provide important insights into prostate health, particularly in men over 50. While an elevated PSA level often raises concerns about prostate cancer, it is not a definitive indicator. Understanding PSA levels, their significance and the next steps to take if your PSA is elevated is crucial in managing your health effectively.
What is PSA and How is it Measured?
PSA is a substance produced by the cells of the prostate gland, and it plays a role in helping semen stay liquid. While some PSA is naturally present in the blood, elevated levels can indicate a variety of prostate conditions.
A Prostate Specific Antigen (PSA) test is a simple blood test where a sample of blood is drawn and analysed in a laboratory to determine the amount of PSA in the blood. It is often used as a screening tool for prostate health, especially in men with a higher risk of prostate conditions.
What Does Elevated PSA Mean?
An elevated PSA level doesn’t necessarily mean you have prostate cancer. Several factors can contribute to raised PSA levels, including:
-
Benign Prostatic Hyperplasia (BPH): BPH is a non-cancerous enlargement of the prostate that commonly occurs as men age. It can cause an increase in PSA levels, but it is not associated with cancer.
-
Prostatitis: Inflammation or infection of the prostate can lead to higher PSA levels. Prostatitis is treatable with antibiotics or other medications, and the PSA levels often return to normal after the infection or inflammation is resolved.
-
Prostate Cancer: While elevated PSA levels can be a sign of prostate cancer, it is not a definitive indicator. Many men with elevated PSA levels do not have prostate cancer, and some men with prostate cancer may have normal PSA levels.
-
Urinary Tract Infections (UTIs) or Recent Procedures: Infections or recent medical procedures, such as a catheter insertion or a prostate biopsy, can temporarily raise PSA levels.
-
Age and Race: PSA levels naturally increase with age. Additionally, African-Australian men may have higher baseline PSA levels compared to other ethnic groups.
PSA Levels: What’s Normal?
PSA levels are measured in nanograms per millilitre (ng/mL). The “normal” PSA range can vary depending on factors such as age and overall health. However, general guidelines suggest:
- Under 4 ng/mL: Generally considered normal for men under 60. For men over 60, a slightly higher level may still be considered normal.
- 4-10 ng/mL: This range is considered mildly elevated, warranting further investigation.
- Above 10 ng/mL: Significantly elevated levels that may indicate a higher risk of prostate cancer.
It’s important to note that PSA levels fluctuate, and a single elevated result isn’t always a cause for concern. Doctors typically look at the trend over time and other factors before making any conclusions.
What Are the Next Steps if PSA Levels Are Elevated?
If you have elevated PSA levels, your doctor may recommend one or more of the following next steps:
-
Repeat PSA Test: PSA levels can vary due to temporary conditions like infections or recent procedures. Your doctor may recommend repeating the test after a few weeks or months to check if the levels have normalised.
-
Digital Rectal Exam (DRE): A DRE is a physical exam where the doctor inserts a finger into the rectum to feel for abnormalities in the prostate. This test can help detect lumps, hardness, or irregularities in the prostate that may suggest cancer.
-
Prostate Biopsy: If your doctor suspects cancer, a biopsy may be recommended. During a biopsy, small samples of prostate tissue are taken and examined under a microscope to check for cancer cells. This is the definitive way to diagnose prostate cancer.
-
Imaging Tests: If there are concerns about cancer spread or other prostate issues, imaging tests like ultrasound, MRI, or CT scans may be used to gather more information.
-
Free PSA Test: This test measures the proportion of PSA in the blood that is not bound to proteins. It can help to differentiate between prostate cancer and other benign prostate conditions like BPH.
The Importance of Discussing PSA Levels with Your Doctor
It’s essential to have a detailed discussion with your healthcare provider about your PSA levels. Elevated PSA doesn’t always indicate cancer, and understanding the context of your individual health history, age, and other risk factors is vital in making informed decisions.
Your doctor will also help guide you through the various testing options available and help you determine the best course of action based on your specific situation. Regular monitoring and early detection are key to effective management, whether that involves further testing or preventive measures.
Conclusion
Elevated PSA levels can be a source of concern, but they don’t necessarily mean you have prostate cancer. PSA is just one part of a larger diagnostic picture. If your PSA levels are elevated, it’s important to consult with your doctor to understand the underlying cause and decide on the next steps, which may include additional testing, monitoring, or treatment options.
Staying informed about prostate health and maintaining regular check-ups can help ensure early detection and a better chance for successful treatment if necessary. Remember, the majority of men with elevated PSA levels do not have prostate cancer, so an elevated result doesn’t always mean the worst.
