This confusion is understandable: the two conditions affect the same organ, often occur at the same age, and can sometimes cause similar symptoms. But their mechanisms, their severity and their management have nothing to do with it.
1. Two different diseases in the same gland
Benign prostatic hypertrophy (BPH), also called prostate adenoma, corresponds to a non-cancerous increase in the volume of the prostate, linked to a normal (but excessive) multiplication of cells in the central area of the gland. It affects around 80% of men over 50, the majority of whom will not develop any bothersome symptoms.
Essential point to remember: benign prostatic hypertrophy never degenerates into cancer and does not increase the risk of developing one. These are two independent biological processes, which also develop in different areas of the prostate — BPH in the central area, cancer most often in the peripheral area.
2. Symptoms that may be similar, very different origins
When BPH becomes symptomatic, it compresses the urethra which passes through the prostate and causes characteristic urinary disorders: weak or intermittent urinary stream, difficulty in starting urination, frequent need to urinate (especially at night), sensation of incomplete emptying of the bladder.
| Feature | Benign Hypertrophy (BPH) | Prostate Cancer |
|---|---|---|
| Frequency after 50 years | Very common (≈ 80 %) | Less common, increases with age |
| Nature | Benign, non-cancerous | Malignant tumor |
| Urinary symptoms | Frequent if large volume | Rare in the early stage, most often absent |
| Detection | DRE (volume increased, soft), ultrasound | PSA, digital rectal examination (hard/irregular consistency), biopsy |
| Progression to cancer | None | Not applicable |
It is precisely this apparent similarity of urinary symptoms which justifies a consultation in the event of a persistent disorder: only a clinical examination, supplemented if necessary with a PSA dosage, makes it possible to distinguish the two situations with certainty.
3. Why localized cancer most often gives no symptoms
Prostate cancer most often develops in the peripheral area of the gland, far from the urethra. This is why, at an early and localized stage, it generally does not cause any urinary discomfort, unlike BPH. When urinary problems are associated with prostate cancer, it is usually because a benign adenoma coexists with it — a common association but without a causal link, the two conditions developing independently of each other in the same man.
This absence of symptoms at the early stage of cancer explains why urinary disorders should never be used, on their own, as a warning signal for or against prostate cancer: their presence most often points towards BPH, while their absence does not rule out early cancer.
4. Living with benign hypertrophy: simple solutions exist
When BPH becomes bothersome, several approaches exist before considering surgery: adjusting your habits (limiting drinks in the evening, reducing caffeine and alcohol), drug treatments that relax the muscles around the prostate or reduce its volume, and as a last resort minimally invasive surgical techniques in the event of significant and persistent discomfort.
⚠️ To remember from a medical point of view
A prostate enlarged on rectal examination, soft and regular, is typical of a benign hypertrophy - a hard or irregular prostate is more likely to be cancer and warrants additional examinations.
It is entirely possible to suffer from BPH and prostate cancer simultaneously: they are two independent diagnoses which each require their own care.
Acute urinary retention (sudden inability to urinate) is a medical emergency, regardless of the underlying cause: it requires immediate consultation.
Tips to remember:
- ●Benign prostatic hypertrophy affects approximately 80% of men over the age of 50 and never develops into cancer — the two conditions are completely independent.
- ●Prostate cancer most often develops in a different area of the gland than BPH, which is why it stays silent much longer.
- ●It is possible to have both conditions at the same time without them being linked: each requires its own monitoring and, if necessary, its own treatment.
- ●Urinary disorders most often point to benign BPH, but their absence does not exclude localized prostate cancer.
- ●Simple solutions exist for bothersome BPH before considering surgery: adjustments to habits, then drug treatments. The Iris Prévention health check-up can help you assess your urinary symptoms.
