The prostate test conversation

My GP is a careful man, the kind of GP who reads guidelines and updates his practice based on them rather than on what was fashionable in 1998. I had asked him for a PSA test the year I turned forty-five, partly because my father had been diagnosed at sixty-two, partly because I had read something on a Sunday morning that made me anxious, and mostly because I had got it into my head that this was the responsible thing to do. He looked at me across the desk and said, "Sure, we can do one. But before we do, can we talk about why you want it?"

I had not expected the question. I had expected him to tick a box. Instead he spent fifteen minutes walking me through what the test actually measures, what an elevated result triggers, what the false positive rate is, what the downstream cascade looks like, and why the Australian guidelines do not recommend routine PSA screening for asymptomatic men. By the end of the conversation I still wanted the test, and I had it, and the result was fine. But I came out of the appointment understanding why this conversation is the one men do not have, and why they should.

Why PSA is not on the standard Australian health check

The standard MBS-funded health assessment for men aged 45 to 49 (or for men 40-plus with risk factors) covers cardiovascular risk, diabetes, kidney function, lipids, blood pressure, and a handful of other things. It does not include a PSA. The Royal Australian College of General Practitioners, the Cancer Council, and the Urological Society of Australia and New Zealand have all settled on a similar position over the last decade, and the position is roughly this:

PSA testing should not be offered as routine population screening. It should be offered in the context of an informed-consent discussion to men aged 50 to 69 who, after understanding the benefits and the harms, choose to be tested. It can be offered earlier (from 40 to 45) to men with a family history of prostate cancer, particularly first-degree relatives diagnosed under 65.

The reason the position is "informed consent, not blanket screen" is the harm-benefit balance. The Cancer Council''s synthesis of the international evidence puts it like this: if you screen 1,000 men aged 55 to 69 with PSA every two years for thirteen years, you prevent roughly one prostate cancer death and you also subject roughly 100 to 200 men to follow-up biopsies, treatments, or surveillance for cancers that would never have caused them harm. The harms (urinary incontinence, erectile dysfunction, anxiety, the cascade of investigations) are real, and they are not rare.

That is not an argument against testing. It is an argument for being deliberate about it.

When to start asking

The rough decision points, based on the current Australian guidance:

• Average risk, no family history: have the conversation with your GP at 50, decide together whether to test
• One first-degree relative diagnosed under 65: have the conversation at 45, possibly 40
• Two or more first-degree relatives, or a relative diagnosed under 60: have the conversation at 40
• BRCA1 or BRCA2 mutation in the family: ask about earlier and more frequent testing, this is a different track
• African ancestry: slightly elevated risk, worth raising at 45

"Have the conversation" is the operative phrase. The conversation is more important than the test. A good GP will walk you through what the result will mean, what the next step is if it comes back elevated, and what your tolerance is for the cascade.

The test itself is a simple blood draw. Most men can have it added to a standard fasting blood panel without any extra needle. The cost on the MBS is modest, and most pathology providers bulk-bill it.

What an elevated PSA actually means

Here is the part that most men do not understand before they get tested, and the part that makes the panic window worse if it comes back high. An elevated PSA does not mean cancer. The PSA test measures prostate-specific antigen, a protein produced by both healthy and cancerous prostate cells, and the level rises with a range of conditions, only some of which are cancer.

Things other than cancer that raise PSA:

• Benign prostatic hyperplasia (the prostate enlarging with age, present in most men over 60)
• Prostatitis (inflammation, often bacterial, sometimes from a recent infection)
• Recent ejaculation (within 24 to 48 hours, can lift PSA modestly)
• Vigorous cycling or horse-riding in the days before the test (mechanical pressure on the prostate)
• Urinary tract infection
• Recent catheterisation or prostate examination
• Age (the "normal" range drifts up with each decade)

The reference ranges most Australian labs use are roughly: under 2.5 ng/mL for men under 50, under 3.5 for men in their fifties, under 4.5 for men in their sixties, and under 6.5 for men in their seventies. Those are generic thresholds, not absolute lines. A more useful number, especially in serial testing, is the rate of change. A PSA rising rapidly from one year to the next (above about 0.75 ng/mL per year) is more concerning than a PSA that has sat at a steady 4.0 for three years.

If your PSA comes back elevated, the next step is almost never a biopsy. The next step is usually a repeat PSA in four to six weeks, with attention to the things that can falsely raise it (no ejaculation for 48 hours, no cycling for a few days, ruling out a UTI). If the second test confirms the elevation, the GP will typically refer to a urologist for further investigation.

The DRE question

The digital rectal examination has a complicated place in modern Australian prostate practice. For decades it was paired with PSA as the standard prostate check. The current evidence is more nuanced. In men with a normal PSA and no symptoms, the DRE adds very little. In men with an elevated PSA, the DRE can add useful information about the texture of the prostate. In men with urinary symptoms, the DRE remains genuinely useful for assessing prostate size.

Most GPs in Australia today will not perform a routine DRE on an asymptomatic man under 60 with a normal PSA. They will do one if you have urinary symptoms (slow stream, hesitancy, frequency, nocturia), if your PSA is elevated, if you have a strong family history, or if you specifically ask. It is a reasonable thing to ask about, and a reasonable thing to decline. The examination is brief, mildly uncomfortable, and not the medieval ordeal that the cultural image suggests.

If you do have a DRE, the urologist or GP is feeling for nodules, asymmetry, or hard areas in the part of the prostate that abuts the rectal wall. It is not a complete examination of the prostate (large parts are out of reach), but it can pick up some palpable cancers that PSA might miss.

The biopsy flow if it gets there

If your PSA is repeatedly elevated and your GP refers you to a urologist, the modern Australian pathway has changed significantly in the last decade. The old reflex was straight to a transrectal ultrasound-guided biopsy. The new pathway, in most major Australian urology practices, is:

• Multiparametric MRI of the prostate first (a non-invasive scan that grades suspicious areas on a 1 to 5 PI-RADS scale)
• If the MRI shows nothing suspicious (PI-RADS 1 or 2), often surveillance with repeat PSA, no biopsy
• If the MRI shows a suspicious area (PI-RADS 3 to 5), targeted biopsy of that specific area, usually transperineal rather than transrectal
• Pathology grading of any cancer found, with a Gleason score that drives the treatment decision

The MRI-first approach has reduced unnecessary biopsies significantly, and the transperineal biopsy (where the needle goes through the perineum rather than the rectum) has lower infection rates. If you end up on this pathway and the urologist is recommending a transrectal biopsy without an MRI first, that is worth questioning. The MRI is now standard of care in most Australian centres.

A handful of things to know about the biopsy itself, if it gets to that point:

• It is done under local or general anaesthetic, takes 20 to 30 minutes, you go home the same day
• There will be blood in your urine, semen, and stool for days to weeks afterwards (this is normal and alarming the first time)
• You will be on antibiotics around the procedure
• Results take 5 to 10 working days
• Even at this point, roughly 60 to 70 percent of biopsies come back negative or show low-grade disease that may not need treatment

The thing nobody quite says

The honest framing of prostate cancer in Australian men is that it is common, and most of it is slow. Roughly one in seven Australian men will be diagnosed with prostate cancer in their lifetime. The five-year survival rate, across all stages, is above 95 percent. Many prostate cancers detected through screening would never have caused symptoms in the man''s lifetime if they had not been found. Some prostate cancers are aggressive and lethal and need to be caught early. The current testing pathway is trying to catch the second category without over-treating the first.

That is why your GP wants to have the conversation rather than just ticking the box. Not because PSA is a bad test, but because it is a test whose value depends on what you do with the result and what your appetite is for the cascade. ASK YOUR DAD. Find out his prostate history, his father''s if he knows it, and bring that to the GP. The family history is the single most useful piece of information in the room.

Test if you understand it. Skip if you understand it. Don''t default.
