What a digital rectal examination involves, what it feels like, and current Australian guidance on when it's actually used.
A digital rectal examination (DRE) is a brief physical examination. The clinician inserts one gloved, lubricated finger a short distance into the rectum to feel the back surface of the prostate gland through the rectal wall.
You'll usually be asked to lie on your side with your knees drawn up, or occasionally to bend forward over an examination table. The exam itself typically takes well under a minute.
Most men describe brief pressure and an urge-to-toilet sensation rather than pain. It shouldn't hurt — tell the clinician if it does, or if you feel unwell at any point.
A DRE can help a clinician feel for hard lumps, irregular texture, or asymmetry in the part of the prostate it can reach. It's also used to assess other causes of pelvic, rectal, or urinary symptoms, not only for cancer detection.
It has real limits worth knowing. A finger can only reach the back surface of the gland — the rest of the prostate can't be felt this way. Many prostate cancers, especially small or early ones, don't cause any change a DRE can detect. A normal DRE does not rule out prostate cancer, and it is not a substitute for a PSA blood test.
A common assumption is that a prostate check means a physical exam. In Australian primary care, that's not the current approach: the PSA blood test is the usual first step, and a DRE is not recommended as a routine addition to it for men without symptoms.
This isn't a recent reversal — it reflects both the RACGP's existing Red Book guidance and PCFA's 2025 draft guidelines (still under consultation, not yet formally adopted), which agree on this point. A DRE is more often performed by a urologist in specific situations, such as after a raised PSA result or before a prostate biopsy, or by a GP when urinary or rectal symptoms give a specific reason to examine.
If you're not sure why a DRE has been suggested, or whether it's appropriate for you, it's reasonable to ask your GP directly — see the PSA test guide for how PSA-based screening decisions are usually made in Australia.
