PSA Screening for Prostate Cancer in Australia: Should You Have a PSA Test?

August 21, 2026/0 Comments/in Blog Post/by drjo

Prostate cancer is one of the most commonly diagnosed cancers in Australian men. One of the difficulties with prostate cancer is that early prostate cancer usually causes no symptoms. By the time symptoms develop, some cancers may already have progressed beyond the prostate.

A simple blood test called the prostate-specific antigen (PSA) test can help identify men who may be at increased risk of prostate cancer. However, PSA testing is not a perfect cancer test and deciding whether to have regular PSA testing involves balancing the potential benefits of early diagnosis against the risks of unnecessary investigation and treatment.

In Australia, there is currently no national population-based prostate cancer screening program. Instead, PSA testing is based on an informed discussion between a man and his doctor, taking into account age, family history, overall health, life expectancy and personal preferences.

What is PSA?

PSA, or prostate-specific antigen, is a protein produced by prostate cells. A small amount normally enters the bloodstream and can be measured with a simple blood test.

An elevated PSA does not automatically mean that you have prostate cancer.

PSA can rise because of:

prostate cancer
benign enlargement of the prostate (BPH)
inflammation or infection of the prostate
urinary infection
recent ejaculation or sexual activity
recent instrumentation of the urinary tract
manipulation of the prostate.

Conversely, some men with prostate cancer can have a PSA within the expected range. PSA is therefore best considered a marker of prostate activity and prostate cancer risk rather than a test that diagnoses cancer.

Who Should Consider PSA Testing in Australia?

Current Australian guidance supports informed, individualized PSA testing rather than universal population screening.

For men at average risk who have been informed about the potential benefits and harms and decide to undergo regular testing, current RACGP guidance recommends offering PSA testing every two years between the ages of 50 and 69 years.

Men with a significant family history may be advised to start earlier. Depending on the strength of the family history, testing may begin from approximately 40–45 years of age and continue every two years to age 69.

A stronger family history includes having a father, brother or multiple close relatives diagnosed with prostate cancer, particularly when prostate cancer occurred at a younger age.

Other factors, including ancestry, genetic predisposition and an individual’s general health and life expectancy, may also influence the decision about when to begin testing.

Importantly, these recommendations apply to men without symptoms. Men with symptoms or clinical findings that raise concern about prostate cancer require individual assessment rather than simply entering a screening program.

What Does an Elevated PSA Mean?

An elevated PSA is not a diagnosis of prostate cancer.

For men aged 50–69 undergoing early detection testing, a PSA above 3.0 ng/mL generally prompts further assessment under current Australian guidance. An abnormal result will often be repeated because PSA levels can fluctuate and temporary elevations are common.

Depending on the PSA level, age, prostate size, family history and other risk factors, further assessment may include:

Repeat PSA → assessment of PSA trend and other risk factors → specialist review → prostate MRI → possible prostate biopsy

Modern prostate cancer assessment has changed substantially. An abnormal PSA no longer necessarily means proceeding directly to a prostate biopsy. Multiparametric MRI (mpMRI) can help identify suspicious areas within the prostate and assist the urologist in deciding whether biopsy is necessary.

The Potential Benefits of PSA Screening

The principal advantage of PSA testing is straightforward:

It may detect a significant prostate cancer while it is still curable.

Aggressive prostate cancer can spread to lymph nodes, bones and other organs. Once metastatic prostate cancer develops, treatment is generally aimed at controlling rather than curing the disease.

Regular PSA testing provides an opportunity to identify some clinically important cancers years before they would otherwise become apparent.

Large screening trials have produced differing results, which is one reason PSA screening remains controversial. European screening data have demonstrated a reduction in prostate cancer mortality associated with PSA-based screening, while other trials have shown less convincing mortality benefits.

For an individual man, therefore, the potential benefit is significant: early detection may identify an aggressive cancer at a stage when curative treatment remains possible.

What Are the Downsides of PSA Screening?

The difficulty is that prostate cancer is not one disease.

Some prostate cancers are aggressive and potentially life-threatening. Others grow extremely slowly and may never cause symptoms during a man’s lifetime.

PSA testing can detect both.

False-positive PSA results

An elevated PSA may lead to anxiety, repeat blood tests, MRI scans and sometimes biopsy even when no cancer is ultimately found.

Overdiagnosis

PSA testing can identify a prostate cancer that would never have caused illness or shortened the man’s life.

This is known as overdiagnosis.

Overtreatment

If an insignificant cancer is diagnosed and subsequently treated, the man can potentially experience treatment complications without gaining a meaningful survival benefit.

Potential consequences of prostate cancer treatment include:

erectile dysfunction
urinary incontinence
urinary symptoms
ejaculatory changes
bowel symptoms following some forms of radiotherapy.

This is one of the major reasons Australia does not currently have a universal PSA population-screening program.

Importantly, however, diagnosing prostate cancer does not automatically mean treating it.

Many men with low-risk prostate cancer are now managed with active surveillance, involving PSA monitoring, MRI and selective repeat biopsy. Treatment is reserved for evidence that the cancer is becoming more significant.

What Are the Implications of Not Having PSA Screening?

Choosing not to undergo PSA testing is also a legitimate decision, particularly after considering the benefits and disadvantages.

The advantage is avoiding the potential cascade of:

PSA testing → abnormal result → anxiety → MRI → biopsy → diagnosis of an insignificant cancer → possible unnecessary treatment.

However, there is another side to this decision.

Because early prostate cancer frequently produces no symptoms, a man who does not undergo PSA testing may remain unaware that he has prostate cancer.

For most men who never develop clinically significant disease, this causes no harm.

For a smaller group who develop aggressive prostate cancer, however, the first indication of the disease may occur after the cancer has grown substantially or spread beyond the prostate.

At that stage, the opportunity for curative treatment may have been reduced or lost.

The decision is therefore not simply:

“Do I want to know whether I have prostate cancer?”

A more useful question is:

“Given my age, health, family history and personal priorities, do the potential benefits of finding a significant prostate cancer early outweigh the potential harms of investigating and possibly diagnosing a cancer that may never affect me?”

This is why shared decision-making with your GP or urologist is important.

What About a Digital Rectal Examination?

The digital rectal examination, or DRE, involves a doctor gently inserting a gloved, lubricated finger into the rectum to examine the back surface of the prostate.

The doctor assesses the prostate for abnormalities such as:

unusual hardness
nodules
asymmetry
irregularity
loss of the normal contour of the gland.

Historically, DRE was routinely combined with PSA testing for prostate cancer screening.

This has changed.

DRE is no longer recommended as a routine screening test in asymptomatic men

Current Australian guidance states that DRE should not routinely be added to PSA testing for early detection in asymptomatic men in primary care.

There are several reasons.

A finger can examine only part of the prostate. Small cancers may not be palpable, and cancers in areas of the prostate that cannot be reached during examination can be missed. A normal DRE therefore does not exclude prostate cancer.

Conversely, benign prostate enlargement and other abnormalities can sometimes produce an abnormal examination.

Does DRE Still Have a Role?

Yes.

Not recommending DRE as a routine screening test does not mean that the examination has become obsolete.

A urologist may perform a DRE when assessing a man with:

an elevated or rising PSA
urinary symptoms
suspected prostate disease
an abnormal MRI
concern about locally advanced prostate cancer
other pelvic or rectal symptoms.

Occasionally, a prostate cancer may produce a distinctly hard or irregular prostate even when the PSA is not dramatically elevated. An abnormal DRE can therefore remain clinically important and may prompt further investigation. Cancer Council Australia notes that urologists will commonly perform DRE as part of prostate assessment even though GPs no longer routinely use it for screening asymptomatic men.

The key distinction is:

DRE has a role in clinical examination and investigation, but it is not recommended as a routine population-screening test in an otherwise well man undergoing PSA testing.

PSA Screening Is About Risk, Not Just a Number

One of the most important changes in modern prostate cancer detection is moving away from treating PSA as simply “normal” or “abnormal.”

A PSA result should be interpreted in context.

Your doctor or urologist may consider:

your age + PSA level + change in PSA over time + family history + prostate size + symptoms + examination findings + MRI findings + overall health

Together, these provide a much more meaningful assessment of prostate cancer risk than a single PSA result.

Should I Have a PSA Test?

There is no single answer that is appropriate for every man.

For a healthy man in the appropriate age group, particularly someone with a family history of prostate cancer, the potential benefit of identifying an aggressive cancer while it remains curable may be important.

For an older man with substantial medical problems or limited life expectancy, the likelihood that PSA screening will provide meaningful benefit becomes considerably smaller. Current Australian guidance advises against PSA testing in men whose life expectancy is likely to be less than approximately seven years because a mortality benefit from early detection is unlikely to occur within that period.

The decision should therefore be individual rather than automatic.

The Bottom Line

PSA testing can save lives by detecting clinically significant prostate cancer at an earlier and potentially curable stage, but it can also detect cancers that would never have caused harm.

Australia therefore does not currently operate a universal PSA screening program. Instead, men are encouraged to make an informed decision about PSA testing after discussing their individual risk and the potential benefits and harms with their doctor.

For men who choose screening, current Australian guidance generally supports PSA testing every two years from age 50–69 for men at average risk, with earlier testing considered for men with a significant family history.

A digital rectal examination is no longer recommended as a routine addition to PSA screening in asymptomatic men, but it remains an important component of specialist prostate assessment in selected circumstances.

Concerned about your prostate cancer risk?

If you are considering PSA testing, have a family history of prostate cancer, have noticed a change in your PSA, or have urinary symptoms, discuss your individual risk with your GP or urologist.

Early detection should not simply be about finding more prostate cancers. The goal is to identify the cancers that matter, at a time when something useful can still be done about them.

This information is intended for general education and does not replace individual medical advice. Recommendations may differ according to your age, family history, medical conditions and previous PSA results.

Living with an indwelling urethral catheter

November 23, 2025/0 Comments/in Bladder Surgery, Blog Post, Prostate Surgery, Urethral Surgery/by drjo

An indwelling urethral catheter is a soft tube passed through the urethra into the bladder. A small balloon holds it in place and urine drains into a bag. It may be needed for a few days after an operation or for longer when the bladder cannot empty safely. The reason for the catheter and a plan for review should be clear to the patient and the people helping with their care.[1, 2]

Why might a catheter be needed?

Common reasons include acute urinary retention, an obstruction to urine flow, temporary drainage after surgery, and selected cases of chronic retention when other options are unsuitable. In hospital, a catheter may be used to monitor urine output in a critically ill person or manage bleeding and clots. It can occasionally support comfort at the end of life. A urethral catheter is generally not the first response to urinary leakage alone.[1]

When practical, the team should discuss whether the catheter can be removed after a trial of void, whether intermittent self-catheterisation is possible, or whether a suprapubic catheter may be more suitable for longer-term drainage. The best choice depends on bladder function, dexterity, the underlying condition and the person’s wishes.[1, 3]

What might it feel like, and what can go wrong?

Some people notice discomfort or a sense of needing to pass urine after insertion. Bladder spasms can cause cramping or urine to leak around the tube. Leakage can also mean that the catheter is kinked or blocked, so it should be checked rather than simply treated as incontinence. Other possible problems include blood in the urine after insertion or a change, skin irritation, accidental pulling or displacement, blockage from debris or encrustation, and infection.[2, 3]

A long-term urethral catheter can also cause pressure or trauma at the urethral opening; persistent soreness or a change in its appearance deserves review. Bladder stones and repeated blockages are further reasons to reassess the drainage plan. The longer a catheter remains, the more opportunity there is for bacteria to colonise it, so it should stay in place only while needed.[3, 4]

How often should a long-term catheter be changed?

There is no single safe change interval for every catheter and every patient. The plan depends on the catheter material and manufacturer’s instructions, local nursing policy, comfort, drainage, and whether it repeatedly blocks or becomes encrusted. Some community protocols plan changes approximately every four to eight weeks, but an individual plan may differ. The interval should not exceed the relevant product’s recommended duration.[1, 3]

Changing a catheter more frequently just to prevent infection has not been shown to help. A catheter may instead need an earlier change if it is blocked, damaged, displaced, causing problems, or as part of managing a symptomatic infection. People with a history of difficult insertion, urethral injury or bleeding should have a specific plan for who can safely perform the change.[1, 3]

At each review, it is worth asking: Is the catheter still necessary? Could a trial without it or another drainage method be considered?[1]

Day-to-day care at home

Keep the drainage bag below bladder level, avoid kinks in the tubing, and secure the catheter so it does not pull. Wash your hands before and after handling the bag. Follow the nurse’s instructions for emptying it and for cleaning the area where the catheter enters the body. Ordinary hygiene is usually enough; do not disconnect the closed drainage system, flush the catheter or take preventive antibiotics unless your treating team has given a specific instruction.[3, 5]

Drink according to your usual health advice. If you have a fluid restriction for heart or kidney disease, follow that plan rather than trying to drink extra to “flush” the catheter. Ask your nurse which supplies to keep at home and whom to call after hours if drainage stops.[2]

Bacteria in urine: when are antibiotics needed?

With a catheter in place, bacteria commonly grow on the catheter surface. After a month, bacteriuria is found in nearly everyone with a long-term catheter. A positive urine culture without symptoms usually reflects colonisation, not an infection requiring antibiotics. Routine screening or treatment of asymptomatic bacteriuria is generally discouraged because antibiotics can cause side effects and encourage resistant bacteria. Exceptions include pregnancy and certain invasive urological procedures, where the treating team will advise on testing and treatment.[4, 6]

Seek clinical assessment for possible infection if you develop fever, rigors, new pelvic or flank pain, feel distinctly unwell, or have other new symptoms that could indicate infection. In a frail person, a new change in function or confusion warrants assessment of several possible causes rather than automatically assuming a UTI. Cloudy or strong-smelling urine, sediment, or a positive dipstick on its own does not usually justify antibiotics.[4, 6, 7]

When a symptomatic catheter-associated UTI is suspected, a clinician should assess you and arrange a properly collected urine specimen if indicated—not from the drainage bag. Treatment is chosen in light of symptoms, culture results, allergies and local guidance. If the catheter has been in place for more than two weeks and still needs to remain, changing it as part of treatment is commonly recommended. Routine antibiotics at every scheduled catheter change are not recommended.[7, 8]

When to get help promptly

Contact your nurse or doctor promptly if urine stops draining, the catheter falls out, you have significant pain or new bleeding, or urine is leaking around the catheter with little in the bag. Check for a kink or a full bag, but do not forcefully flush or reinsert a catheter yourself unless specifically trained and instructed. Seek urgent medical care if drainage has stopped and you have a painful or swollen lower abdomen, or if you have fever, shaking chills or feel seriously unwell.[2]

Catheter support in Bundaberg

Some people can have catheter assessment and planned changes at home through a community nursing service. Ozcare and BlueCare provide home nursing in the Bundaberg area; whether a nurse can provide catheter care for an individual depends on referral, staffing, clinical needs, service area and funding arrangements. Ask the provider directly about availability and costs before relying on a visit.[9, 10]

For my Bundaberg patients, Sandra Ilett, a continence nurse with Community Nurse Service, is another local contact for bladder and catheter-related care. Sandra and her colleague Carla Kerr have also seen patients at the nurse-led clinic at The Friendlies Medical Suites. Patients can discuss a suitable referral and whether a home visit or clinic appointment is available. Community Nurse Service: (07) 4126 2002.[11] This mention recognises local nursing support; it is not a claim that one service is preferable for every patient.

A written catheter plan should record the reason for drainage, catheter details, the planned review or change, who will provide care, and whom to call if problems arise. Community nurses, the GP and urology team can then coordinate care across visits.

This article provides general information. Follow your individual catheter plan and seek clinical advice for new symptoms or a catheter that is not draining.
