Got a PSA report and not sure what the number means? A high PSA does not always mean cancer. Here is how to read your result and what to do next.
Many men first hear about PSA when it shows up on a routine health checkup. Then the report comes back with a number marked “high”, and worry sets in.
The good news: a raised PSA is common, and most of the time it is not cancer. PSA can rise for many simple reasons, such as an enlarged prostate or an infection. Still, it should never be ignored. The right next step depends on your age, your number, and how it changes over time.
Below, we explain the PSA test in simple words.
At a glance
PSA stands for Prostate-Specific Antigen. It is a protein made by the prostate gland, a small gland below the bladder in men.
A small amount of PSA normally enters the blood. The PSA test is a simple blood test that measures how much. The result is shown in ng/mL (nanograms per millilitre).
When the prostate is enlarged, inflamed or has cancer, more PSA can leak into the blood, and the number goes up.
For many years, below 4 ng/mL was treated as “normal”. Doctors now know PSA naturally rises with age as the prostate grows. Many urologists use age-based ranges as a guide:
| Age | Usual upper limit of PSA |
|---|---|
| 40–49 years | Up to 2.5 ng/mL |
| 50–59 years | Up to 3.5 ng/mL |
| 60–69 years | Up to 4.5 ng/mL |
| 70–79 years | Up to 6.5 ng/mL |
These are general guides, not strict cut-offs. A “normal” number does not fully rule out cancer, and a “high” number does not confirm it.
As a rough guide to the overall number:
Usually considered low risk.
Cancer is possible, but an enlarged prostate or infection is more common.
A higher chance of cancer. Needs prompt review by a urologist.
Many things can push PSA up for a short time:
Finasteride and dutasteride, often given for an enlarged prostate or hair loss, can cut PSA roughly in half. Always tell your doctor if you take them, so your result is read correctly.

To get an accurate result:
A single high reading is not a diagnosis. Your urologist will usually take these steps:
PSA can rise for a short time. A repeat test after a few weeks often settles the question, especially if there was an infection or a recent trigger.
The doctor may gently feel the prostate to check its size and whether it feels firm or uneven.
Free PSA: PSA exists in two forms in the blood. A low free PSA percentage points more towards cancer, and a high one points more towards an enlarged prostate.
PSA density: your PSA compared with the size of your prostate.
PSA velocity: how fast your PSA rises over time. A steady, quick rise matters more than one high number.
An MRI shows whether any area of the prostate looks suspicious. Results are scored on a scale called PI-RADS. The MRI helps decide whether a biopsy is needed, and guides it to the right spot.
A biopsy takes tiny samples of prostate tissue to check for cancer. It is the only test that confirms prostate cancer.
Many men stop at Step 1 or 2 because the repeat PSA comes back normal, or the cause turns out to be harmless.
PSA testing is a personal decision. Talk to your doctor about it, especially if you are:
Early prostate cancer often causes no symptoms at all. Regular checks can find it early, when treatment works best.

No. Most men with a raised PSA do not have cancer. An enlarged prostate, infection or recent activity are common causes. Further tests are needed to know for sure.
For men aged 60–69, PSA up to about 4.5 ng/mL is generally within the expected range. Your doctor will also look at your trend over time.
Yes. Urine and prostate infections can raise PSA for several weeks. The test is usually repeated after the infection is treated.
No. It is a simple blood test taken from the arm.
It depends on your age, risk and past results. Men with low PSA may test every 2 years, while others may need yearly tests. Your urologist will advise.
