1. “A high PSA necessarily means cancer”
False. As detailed in our article on screening, PSA is not specific to cancer: benign hypertrophy, a urinary infection or even recent sexual intercourse can temporarily raise its level. A high PSA triggers additional tests, not an automatic diagnosis.
2. “Prostate cancer only affects older men”
True, for the most part, but with nuances. This cancer remains rare before the age of 45 and mainly affects men over 65. However, certain factors (heredity, BRCA2 mutation, ethnic origin) may justify vigilance from the age of 40-45, as detailed in our article on risk factors.
3. “An enlarged prostate is a sign of cancer”
False. As explained in our fourth article, benign prostatic hypertrophy affects 80% of men after the age of 50 and never degenerates into cancer. These are two independent conditions, which can coexist without a cause and effect link.
4. “Without urinary symptoms, I risk nothing”
False — and this is undoubtedly the most important misconception to correct. Localized prostate cancer most often does not cause any urinary symptoms, unlike benign enlargement. The absence of disorder therefore does not rule out early cancer.
5. “Prostate cancer is rarely curable”
False. It is even one of the cancers with the best prognosis: 5-year survival exceeds 93% in France, and mortality linked to this cancer has been decreasing regularly since the 1990s.
6. “A cancer diagnosis means immediate treatment”
False, in many cases. As detailed in our article on active surveillance, a significant proportion of low-risk prostate cancers can be closely monitored for years, without immediate treatment, with very reassuring long-term follow-up data.
7. “Treatments always leave permanent after-effects”
False, but the impacts are real and should not be minimized. Urinary continence is restored in the majority of cases within 3 to 6 months after a prostatectomy, with the help of perineal rehabilitation. Sexual disorders, more frequent and sometimes lasting, today benefit from varied solutions at each stage.
8. “Diet can prevent this cancer, as with other cancers”
False, based on current knowledge. Unlike colorectal cancer, no firm dietary recommendations have been validated by scientific authorities for the prevention of prostate cancer — even if certain avenues (tomato, soy) remain actively studied.
9. “Physical activity is of no use once cancer is diagnosed”
False, and it's even the opposite. Physical activity after diagnosis reduces overall mortality by about 38%, regardless of the stage of the disease — a benefit that is seen even in men who start moving after diagnosis.
10. “We must not talk about it, it’s a man’s affair that he can resolve alone”
False, and this is perhaps the most damaging misconception. Male modesty around the prostate often delays consultations, treatment decisions and support for after-effects (continence, sexuality). Talking about it openly, to your doctor and to your loved ones, concretely improves the quality of care and experience.
| Received idea | True or False | Reference article |
|---|---|---|
| High PSA = definite cancer | False | Article 2 |
| Prostate enlarged = cancer | False | Article 4 |
| No symptoms, no risk | False | Article 1 and 4 |
| Rarely heals | False | Article 1 |
| Diagnosis = immediate treatment | False | Article 9 |
| Sport useless after diagnosis | False | Article 6 |
⚠️ In summary on the medical level
Prostate cancer remains one of the cancers with the best prognosis, provided it is detected and managed with a strategy adapted to each individual situation.
Neither silence nor haste are good strategies: reasoned early detection, active surveillance when indicated, and comprehensive support for quality of life form a whole. consistent.
If in doubt about your personal situation, your GP or a urologist remains the reference point of contact.
Tips to remember:
- ●A high PSA is never a diagnosis in itself: it triggers additional tests, not an automatic conclusion.
- ●Localized prostate cancer most often does not cause any urinary symptoms - the absence of a disorder therefore does not rule out its presence.
- ●A significant proportion of low-risk prostate cancers can be monitored without immediate treatment, with very reassuring follow-up data.
- ●Physical activity after a diagnosis reduces overall mortality by around 38%: a benefit which is observed even in the event of late recovery.
- ●This series is coming to an end, but vigilance remains an ongoing gesture: talk about your risk factors with your doctor and take stock with the Iris Prévention health check.
