Should I Have a PSA Test?

Yes. Thats the short answer.

Choosing whether or not to have a PSA (Prostate-Specific Antigen) test is one of the most significant health decisions a man can make. While the test is a simple, the results can lead to a complex pathway of further investigations, treatments, and peace of mind.

Below, we break down why this screening is vital, what a high result actually means, and why early detection is the “gold standard” in men’s health.

1. Why Screening Matters: The Reality of Prostate Cancer

Aside from non-melanoma skin cancer, prostate cancer is the most common cancer diagnosed in men. Many people mistakenly believe it is an “old man’s disease,” but the statistics tell a different story: 40% of all prostate cancer cases are diagnosed in men under the age of 65.

Because early-stage prostate cancer rarely causes noticeable symptoms—such as difficulty urinating or back pain—the PSA test serves as an essential “early warning system.” Without regular screening, the disease is often only discovered after it has spread beyond the prostate, making it much harder to manage.

2. Understanding the PSA Test: High PSA $\neq$ Cancer

A common source of anxiety for men is a “positive” or elevated PSA result. However, it is crucial to understand that an elevated PSA level does not automatically mean you have cancer.

The PSA is a protein produced by both normal and cancerous cells in the prostate gland. Many non-cancerous conditions can cause your PSA levels to spike, including:

• BPH (Benign Prostatic Hyperplasia): A common, non-cancerous enlargement of the prostate.

• Prostatitis: Inflammation or infection of the prostate gland.

• Recent Activity: Even vigorous exercise (like cycling) or recent sexual activity can temporarily raise PSA levels.

In fact, only about 25% of men who undergo a prostate biopsy due to an elevated PSA are actually found to have cancer. The test is a starting point for a conversation, not a final diagnosis.

3. The Power of Early Detection

If the PSA test does lead to a cancer diagnosis, there is a massive silver lining: nearly 99% of prostate cancer cases are treatable—and often curable—if caught in the early stages.

Modern medicine offers a variety of paths for early-stage diagnosis:

• Active Surveillance: For slow-growing “low-risk” cancers, doctors may simply monitor the patient closely without immediate surgery or radiation.

• Targeted Treatments: Advances in robotic surgery and precision radiotherapy have significantly reduced side effects compared to a decade ago.

The goal of the PSA test is to find the “window of opportunity” where the cancer is still confined to the prostate gland, where the survival rate remains incredibly high.

4. Should You Get Tested? (The Pros and Cons)

The decision to screen should be a shared discussion between you and your GP or urologist. Here is a summary to guide your choice:

Summary: Taking Control of Your Health

The PSA test is not a perfect tool, but it is the best one we currently have for the early detection of a disease that affects millions of men.

If you are over the age of 50 (or 45 if you have a family history or are of African-Caribbean descent), you should discuss the PSA test with your healthcare provider.

Don’t panic if your levels are elevated; remember that the majority of these cases are due to benign causes. However, don’t ignore the opportunity to catch a treatable condition while time is on your side.
