PSA testing: the conversation worth having
Unlike bowel, breast and cervical screening, there is no national prostate screening program in Australia. That is not an oversight — it reflects a genuine balance of benefit and harm, and it means the decision is yours to make with your GP.
The short version
- PSA is a protein made by the prostate. A raised level can indicate cancer, but also several harmless things.
- Australian guidelines suggest offering the test every two years from 50 to 69 to men who decide to have it after an informed discussion.
- Men with a family history may be offered testing from 40 or 45. Bring what you know about your family.
- Symptoms are a separate matter. Urinary changes, blood in urine or semen, or bone pain need an appointment regardless of testing.
Prostate cancer is the most commonly diagnosed cancer in Australian men. That fact alone makes people assume there must be a screening program, and there is not. Understanding why is the key to making a good decision.
What the test measures
PSA is prostate-specific antigen, a protein made by the prostate and measured in a blood test. A raised level can indicate cancer. It can also be raised by an enlarged prostate, which is extremely common with age, by infection or inflammation, by recent cycling, or by ejaculation in the preceding days.
Equally, some prostate cancers do not raise PSA at all. So the test is neither definitive when it is high nor entirely reassuring when it is normal.
Why there is no screening program
Because prostate cancer behaves so variably. Many prostate cancers grow so slowly that they would never have caused symptoms or shortened life. Others are aggressive. The PSA test cannot reliably tell them apart.
That creates a genuine trade-off:
- The benefit: finding aggressive cancer early, when it is more treatable.
- The harm: finding slow cancers that would never have troubled you, and then treating them — with potential effects on continence and sexual function that are permanent.
- And in between: false alarms that lead to biopsies, with their own anxiety and small risks.
Reasonable, well-informed men reach different conclusions about that trade-off. That is precisely why it is framed as a decision rather than a recommendation.
What the guidelines actually say
Australian guidance is that men aged 50 to 69 who, after being told about the benefits and harms, decide they want testing should be offered PSA every two years.
Men with a father or brother who has had prostate cancer are at higher risk, and testing may be offered from 40 or 45 depending on how strong the family history is. If several relatives have been affected, or any were diagnosed young, say so — it changes the advice.
Routine testing is generally not recommended for men whose life expectancy is under about seven years, because the harms outweigh any realistic benefit.
Before the blood test: avoid vigorous exercise, long cycle rides and ejaculation for 48 hours beforehand, and tell your GP if you have had a urinary infection recently. Any of these can raise the result and cause an unnecessary scare.
What happens if it comes back raised
Not a biopsy the next day. Usually the test is repeated, because a single raised result is frequently transient. Your GP will consider your age, the trend over time, your prostate size on examination and your family history together.
If concern persists, the next step is commonly an MRI rather than proceeding straight to biopsy. MRI has substantially improved this pathway — it helps identify who genuinely needs a biopsy and where to target it.
Where cancer is found and it is low risk, active surveillance is often the right answer: monitoring carefully rather than treating immediately. A great many men are on surveillance and remain well.
Symptoms are a different conversation
Screening is for men without symptoms. Book an appointment regardless of any testing decision if you have:
- Difficulty starting, a weak stream, or dribbling afterwards
- Getting up several times a night to pass urine
- Blood in your urine or semen
- Pain passing urine
- New persistent back, hip or pelvic pain
Most of these turn out to be benign prostate enlargement, which is common and treatable. They still need assessing properly.
How to approach the appointment
Ask for a long appointment and say it is about prostate health. Bring what you know about your family history. And be prepared for your GP to ask what you would want to do with the information — because for this test, more than most, that question genuinely shapes whether having it is the right call.
Questions we get asked
Should I have a PSA test?
That depends on your age, your family history and how you weigh the trade-offs. Australian guidance is to offer testing every two years from 50 to 69 to men who want it after an informed discussion. Your GP will go through what applies to you.
Does a normal PSA mean I don't have prostate cancer?
Not entirely. Some prostate cancers do not raise PSA. That is one of the reasons it is not used as a population screening test, and why symptoms should always be assessed in their own right.
Is the PSA test bulk billed?
The appointment is bulk billed on weekdays with a valid Medicare card, and most pathology is bulk billed by the laboratory. The laboratory will tell you if anything is not covered before they take the sample.
