Most men carry a rule of thumb about prostate testing that goes something like “ask about it at fifty”. For a meaningful minority of men, that rule is now wrong, and it is wrong in the direction that matters.
Australia’s guidelines for the early detection of prostate cancer were rewritten this year. The Prostate Cancer Foundation of Australia developed them and the National Health and Medical Research Council approved them on 18 May 2026. The change worth knowing about is not a new test or a new treatment. It is that the starting point now depends on your family history, and most of the men it applies to have no idea they qualify.
What actually changed
The old approach treated men as one group. The new one sorts them into pathways.
If you are not at higher risk, the conversation is recommended to start at 50, with testing every two years through to 69. Routine testing between 45 and 49 is not recommended, though a test can be offered if you ask for one.
If you are at higher risk, that conversation starts at 45, again every two years. You are considered at higher risk if any of these apply: a brother who has had prostate cancer, a father diagnosed before 65, two or more second-degree relatives who died from prostate cancer, Black sub-Saharan African ancestry, or a known BRCA2 mutation. Any one of these places a man at roughly twice the usual risk.
If you are 70 or over, testing is a clinical judgement rather than a routine offer. It weighs your general health and life expectancy alongside what you would want done with the result.
The guidelines also changed the number at which a result prompts action, and the number now moves with your age and risk. For men at usual risk aged 50 to 69, that level is 3.0 micrograms per litre. For men at higher risk it is 2.0 between 50 and 69, and 1.0 between 45 and 49. From 70 it is 5.5. A single raised result is not a diagnosis. It is repeated within one to three months, and only a confirmed result leads to referral.
One further change is worth knowing because it removes a step people fear. Where further assessment is needed, an MRI now comes before any biopsy, and a proportion of men who would once have gone straight to biopsy will not need one.
Two things you may have read that are not right
Some coverage this year described the new guidelines as mandating testing. They do not. Testing is offered after a discussion, and the decision remains yours.
Other coverage described baseline testing from age 40 for all men. That is not what the approved guidelines say. There is no recommendation for routine testing of all men from 40.
We are naming both because a fair number of men will have read one or the other and drawn a conclusion from it, in either direction.
What this means for you
The useful action here is not booking a test. It is spending five minutes on your own family history.
Do you know whether your father was diagnosed, and at what age? Do you know about your brothers? Second-degree relatives are grandfathers, uncles and half-brothers, and men are often vaguer about that generation than they expect to be. For many families this is a phone call rather than a memory.
If any of the higher-risk criteria apply to you and you are 45 or over, raise it at your next appointment rather than waiting for it to come up. If none apply and you are under 50, there is nothing you need to do about it now.
Separately, and regardless of any of the above: if you have symptoms, that is not a screening question and it should not wait for a screening conversation. Trouble passing urine, blood in the urine or semen, or new and persistent bone pain are all reasons to book an appointment now.
Why we are covering it
September is Prostate Cancer Awareness Month, which is usually the cue for a general reminder to get tested. We are not doing that, because a general reminder does not tell you anything you can act on. A guideline that moved the starting age for a specific and identifiable group of men does.
This article is general information, not personal medical advice. Guideline detail is current as at September 2026. Whether testing is right for you is a decision to make with your GP, informed by your own history and what you would want to do with a result.
