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.
