Prostate Health 101: What PSA Can (and Can’t) Tell You

The PSA (prostate-specific antigen) test is commonly used to help evaluate prostate health. While it is an important tool, PSA results must be interpreted carefully and in context.

What Is PSA?
PSA is a protein made by the prostate gland. A small amount normally enters the bloodstream. Higher levels can signal a change in prostate activity but do not automatically mean cancer is present.

Reasons PSA May Be Elevated
PSA can rise for many non-cancerous reasons, including:

  • Enlarged prostate (benign prostatic hyperplasia – BPH)

  • Prostate infection or inflammation (prostatitis)

  • Recent ejaculation

  • Cycling or pressure on the prostate

  • Recent urinary procedures or catheter use

This is why a single PSA number rarely tells the whole story.

Why Trends Matter More Than One Test
Urologists look at:

  • How PSA changes over time

  • How quickly it rises

  • Your age and prostate size

  • Family history and risk factors

A slow, stable PSA is often reassuring, even if the number is mildly elevated.

What Happens If PSA Is Elevated?
Your provider may recommend:

  • Repeating the PSA test

  • Additional blood or urine testing

  • Imaging studies

  • A biopsy if needed

Each step is chosen carefully based on overall risk and individual factors.

Who Should Discuss PSA Screening?
Men should talk with their provider about PSA screening if they:

  • Are over age 50

  • Have a family history of prostate cancer

  • Are in a higher-risk group

  • Have urinary symptoms or prostate concerns

Screening decisions are personal and should be made through shared decision-making with your provider.

PSA is a valuable screening and monitoring tool, but it is only one piece of the prostate health picture. Proper interpretation prevents unnecessary worry and ensures appropriate follow-up.

When Should You Get Screened for Prostate Cancer?

Prostate screening is one of the most important tools we have to catch issues early—before they become serious. At our urology center, we often get the question: “When should I get screened?” The answer depends on your age, risk factors, and overall health.

General Guidelines

  • Age 50 – Most men should begin routine prostate cancer screening at age 50.
  • Age 45 – Men at higher risk should start earlier. This includes:
    • African American men
    • Men with a father, brother, or son who had prostate cancer before age 65
  • Age 40 – Men with multiple family members affected by prostate cancer may benefit from even earlier screening.

What Does Screening Involve?

Prostate screening typically includes:

  • A PSA blood test (Prostate-Specific Antigen) to check for elevated levels
  • A digital rectal exam (DRE) to feel for any abnormalities in the prostate

These tests are quick, non-invasive, and could make a life-saving difference.

Why Early Detection Matters

Prostate issues—like cancer or benign prostatic hyperplasia (BPH)—can develop with few or no symptoms. Regular screenings help identify changes early, when they’re easier to treat and before complications arise.
