When it comes to men’s health, few blood tests are as well-known—or as misunderstood—as the PSA test. Many men have heard of it, but aren’t sure what it actually measures, who should have it, or what the results mean.

At DDCHealth, we believe that understanding your health is just as important as monitoring it. Here’s what you should know about PSA testing.

What Is PSA?

PSA stands for Prostate-Specific Antigen. It is a protein produced almost exclusively by the prostate gland. A small amount of PSA normally enters the bloodstream, and a simple blood test can measure its level.

Contrary to popular belief, PSA is not a cancer test. Instead, it is a marker that tells your healthcare provider that something may be affecting the prostate.

What Can Cause an Elevated PSA?

An elevated PSA does not automatically mean you have prostate cancer. Several conditions can increase PSA levels, including benign prostatic hyperplasia (BPH), prostatitis, recent ejaculation, vigorous cycling, recent urinary catheter placement or prostate procedures, aging, and prostate cancer.

Because many factors can affect PSA, your provider looks at the whole clinical picture—not just a single number.

Why Is PSA Important?

Prostate cancer is one of the most common cancers in men. The encouraging news is that when it is found early, treatment is often highly effective. PSA testing can sometimes identify changes before symptoms develop, giving men more treatment options and a better chance for excellent outcomes.

The goal isn’t simply to find cancer—it’s to identify men who may benefit from additional evaluation while avoiding unnecessary testing when possible.

What Happens If My PSA Is High?

A high PSA doesn’t necessarily mean you need a biopsy. Depending on your age, symptoms, family history, and PSA level, your healthcare provider may recommend repeating the PSA test, performing a digital rectal examination, ordering additional blood tests or specialized PSA testing, obtaining a prostate MRI, or referral to a urologist.

Many men with elevated PSA levels do not have prostate cancer.

Who Should Consider PSA Screening?

Recommendations emphasize shared decision-making between you and your healthcare provider. In general, men ages 50–69 should discuss the potential benefits and risks of PSA screening. Higher-risk men may benefit from starting earlier, often around age 45. This includes men with a father, brother, or son with prostate cancer; Black or African American men; and men with certain inherited genetic mutations such as BRCA2.

The decision to screen should take into account your overall health, life expectancy, personal values, and family history.

Does Testosterone Therapy Affect PSA?

Men receiving testosterone replacement therapy should have their PSA monitored regularly. Testosterone itself has not been shown to cause prostate cancer, but it can stimulate existing prostate tissue and may uncover an underlying problem sooner. Routine PSA monitoring is considered a standard part of safe testosterone therapy.

Should I Avoid Anything Before My PSA Test?

To help obtain the most accurate result, avoid ejaculation for 24–48 hours before testing, avoid long-distance cycling the day before the test, tell your provider if you’ve had a urinary infection or recent prostate procedure, and share all medications you’re taking—especially those used to treat an enlarged prostate.

Frequently Asked Questions

Is there a “normal” PSA level?

There isn’t one single number that’s considered normal for everyone. PSA levels generally increase with age, and your provider interprets your result based on your age, medical history, prior PSA values, and other risk factors.

If my PSA is normal, does that mean I don’t have prostate cancer?

Not always. While PSA is a valuable screening tool, no test is perfect. Some prostate cancers produce little PSA, which is why screening decisions should always include your symptoms, physical exam, and individual risk factors.

If my PSA is elevated, do I have cancer?

No. Most elevated PSA results are caused by conditions other than prostate cancer.

The Bottom Line

PSA testing is an important tool in men’s preventive health—but it’s only one piece of the puzzle. Rather than relying on a single lab value, your healthcare provider considers your age, symptoms, family history, physical examination, and PSA trend over time to determine whether additional evaluation is needed. The best approach is one that’s personalized to you.
