Understanding Urology: The Medical Specialty Focused on the Urinary Tract

When it comes to prostate health, it’s natural to have questions, especially about screening and what your results mean. PSA testing is one of the most common tools used to evaluate the prostate, but it’s also one of the most misunderstood.

If you’ve been told you need a PSA test, or you’ve already had one, you don’t have to interpret it on your own. At Rose City Urology, we’re here to help you understand what PSA measures, what your results mean, and how testing fits into your overall care.

What PSA Measures

PSA, or prostate-specific antigen, is a protein produced by the prostate gland. Small amounts are normally found in the blood, and levels can vary from person to person.

A PSA test measures how much of this protein is present. Higher levels may indicate that something is affecting the prostate, but it’s important to understand that PSA is not a diagnosis on its own.

Elevated PSA levels can be associated with:

PSA is best viewed as a signal that helps guide next steps, not a definitive answer.

Normal vs. Elevated PSA Levels

H2: Normal vs. Elevated PSA Levels

There isn’t a single “normal” PSA level that applies to everyone. Levels can vary based on age, health, and individual baseline.

In general:

  • PSA tends to increase gradually with age
  • Slight elevations are common and not always concerning
  • Trends over time are often more meaningful than a single result

Even when PSA is elevated, it does not automatically mean cancer. Many non-cancerous conditions can raise PSA levels, which is why interpretation always requires context.

We look at your results alongside your symptoms, health history, and risk factors, so decisions are thoughtful and personalized.

Factors That Can Affect PSA Results

PSA levels can be influenced by a range of factors, many of which are temporary or non-cancerous.

Common contributors include:

  • Benign prostate enlargement (BPH)
  • Prostatitis (inflammation or infection)
  • Urinary tract infections
  • Recent ejaculation
  • Activities like cycling that place pressure on the prostate
  • Recent procedures or catheter use

Because of this, an elevated PSA is often rechecked before moving forward with further testing. This helps ensure accuracy and avoids unnecessary concern.

How PSA Fits Into Screening Decisions

PSA testing is one tool in a broader, personalized approach to prostate health.

Screening decisions are based on:

  • Age
  • Family history
  • Individual risk factors
  • Personal preferences

Rather than relying on a single result, we focus on a comprehensive evaluation.

If your PSA is elevated, next steps may include:

  • Repeating the PSA test to confirm results
  • Tracking PSA changes over time (PSA velocity)
  • A digital rectal exam (DRE)
  • Imaging or additional testing
  • Prostate biopsy, if indicated

In many cases, monitoring over time is appropriate, especially when changes are mild or explained by other factors. Our goal is to ensure you have clear answers and a plan that feels right for you.

Frequently Asked Questions About PSA Testing

Does a high PSA mean I have prostate cancer?
Not necessarily. Many non-cancerous conditions can raise PSA levels. Further evaluation helps determine the cause.

Why would my PSA need to be repeated?
PSA levels can fluctuate due to temporary factors. Repeating the test helps confirm whether the elevation is persistent.

What happens if my PSA continues to rise?
We may recommend additional evaluation, such as imaging or further testing, to better understand the cause.

Is PSA testing recommended for everyone?
Not always. Screening decisions are individualized and based on your risk factors and preferences.

What is PSA velocity?
PSA velocity refers to how quickly your PSA levels change over time. This can provide additional insight beyond a single test result.

Take the Next Step

PSA testing is a valuable tool, but understanding what it means is just as important as the test itself.

You don’t have to navigate this alone. We’re here to listen, explain your results clearly, and help you make informed decisions about your health, based on your goals, your risk, and what matters most to you.
