Prostate cancer screening: do I need a PSA test?
What Australia’s 2026 guidelines mean for your age, your risk and your next GP appointment.
A blood test is straightforward. Deciding whether you need it deserves a conversation.
Australia’s 2026 Guidelines for the Early Detection of Prostate Cancer bring a more personalised approach to testing. Developed by the Prostate Cancer Foundation of Australia and Cancer Council Australia, and approved by the NHMRC, they replace the 2016 guidelines. The aim is to detect potentially harmful cancers earlier while reducing unnecessary investigations and treatment.
So, what does that mean for you?
What does a PSA test actually tell us?
PSA stands for prostate-specific antigen, a protein produced by the prostate gland. A PSA blood test measures how much is circulating in your blood.
Despite its name, PSA is specific to the prostate, not to prostate cancer. Levels can rise because of non-cancerous enlargement, infection or other prostate conditions. A raised result does not automatically mean cancer, and a result within the expected range cannot completely rule it out.
Think of PSA as information that helps guide the next step, rather than a diagnosis on its own.
Why isn’t testing simply recommended for everyone?
Early prostate cancer often causes no symptoms. PSA testing can help identify a potentially harmful cancer before it spreads and may reduce the risk of dying from prostate cancer.
However, testing has limitations. An abnormal result can lead to worry and investigations that ultimately find no cancer. Testing can also detect a slow-growing cancer that would never have caused problems during someone’s lifetime. This is called overdiagnosis.
Unnecessary treatment matters because prostate cancer treatments can affect bladder control, sexual function and quality of life.
The decision is therefore about balancing potential benefits and harms against your individual circumstances and preferences. Australia does not currently have an invitation-based national prostate cancer screening program. Testing is discussed and arranged through your GP.
When should I consider PSA testing?
The following recommendations apply to people who choose testing after discussing its possible benefits and harms.
Ages 45–49: your risk makes a difference
For people at standard risk, routine testing is not recommended at this age. However, an initial PSA test can be discussed with your GP.
If that initial result is below 1.0 µg/L, no further routine testing is recommended until age 50.
For people at higher risk, PSA testing may be offered every two years from age 45.
Ages 50–69: make a testing plan
Your GP should initiate a discussion about prostate cancer risk and testing.
For those who choose testing, the recommended interval is every two years. People at higher risk generally follow the same interval, but a lower PSA level prompts further assessment.
Age 70 and over: your health matters, not just your birthday
Turning 70 does not automatically mean testing must stop.
The decision considers your overall health, other medical conditions, life expectancy and preferences. Testing is generally offered only when life expectancy exceeds seven years, because the benefits take time to emerge.
Where appropriate, testing may continue every two years. Stopping may be reasonable when PSA is below 5.5 µg/L, following an individual discussion with your GP.
What puts someone at higher risk?
Family history is more useful when we know who was affected and their age at diagnosis.
Important higher-risk factors include:
- A significant family history, such as a brother with prostate cancer, a father diagnosed before 65, or two or more second-degree relatives, such as uncles or grandfathers, who died from prostate cancer.
- A BRCA2 gene mutation. Other inherited cancer syndromes can also affect risk.
- Black sub-Saharan African ancestry.
Importantly, a father diagnosed at an older age, or two or more second-degree relatives diagnosed with prostate cancer, may also justify the higher-risk pathway. Tell your GP about all affected relatives, not just those diagnosed young.
What happens if my PSA is raised?
The guidelines use different action levels depending on age and risk. These are levels that prompt follow-up, not numbers that diagnose cancer.
| Age and risk group | PSA action level |
|---|---|
| Ages 45–49, when testing is undertaken | 1.0 µg/L or above |
| Ages 50–69, standard risk | 3.0 µg/L or above |
| Ages 50–69, higher risk | 2.0 µg/L or above |
| Age 70 and over, when testing is appropriate | 5.5 µg/L or above |
At or above the relevant level, the usual next step is a repeat PSA test within one to three months. If the result remains elevated, your GP will discuss referral to a urologist for further investigation.
A raised PSA does not mean an immediate biopsy
When further investigation is needed, a multiparametric MRI, a detailed scan of the prostate, is recommended before deciding whether a biopsy is necessary.
MRI helps identify suspicious areas and guide a biopsy when one is needed. It can also help some people avoid an unnecessary biopsy. Your specialist will interpret the scan alongside your PSA and individual risk.
Even if cancer is diagnosed, immediate treatment is not always necessary. Some low-risk cancers are managed with active surveillance, a structured monitoring plan rather than immediate surgery or radiotherapy. This is ongoing care, not simply ignoring the cancer.
Does a prostate check involve a rectal examination?
Not routinely.
A digital rectal examination is not recommended as a routine addition to PSA testing and risk assessment in general practice. It may still be needed during further assessment, particularly with a urologist.
What if I have symptoms?
Do not wait for your next screening test to discuss a new symptom.
Changes in urination, pain when passing urine, blood in the urine or persistent pelvic discomfort need medical assessment. These symptoms often have causes other than prostate cancer, but they should not be dismissed because you are younger than the usual testing age or previously had a reassuring PSA result.
Investigating symptoms is different from routine screening.
Let’s make a plan that makes sense for you
At Walker Street Doctors, we want you to leave with more than a pathology request. We want you to understand why a test is being considered, what the result might mean and what happens next.
Bring your questions, any previous PSA results and what you know about your family history. We’ll work through the decision together.
Book a prostate health discussion with your Walker Street Doctors GP in North Sydney. You don’t need to arrive with the answers.
