Urologists in Catalonia are warning against online misinformation about prostate cancer, one of the most commonly diagnosed tumours among men. They say unverified posts on social media and the internet are creating confusion about the illness and its treatment.
One of the most repeated claims is that ejaculating 21 times a month protects against prostate cancer. Specialists say there is no scientific evidence for that advice. Some research has found a statistical association between higher ejaculation frequency and a slightly lower risk, but that is not the same as proof of cause and effect.
Doctors also caution that many people search for medical information online before speaking to a professional. That can lead to misunderstandings about tests, treatments and risk factors. For readers following health coverage in Catalonia, our news page carries more local reporting.
Urologists set out several common myths. Early-stage prostate cancer can have no symptoms. A high PSA result does not always mean cancer, because other benign conditions can raise it. A normal digital rectal examination also does not rule the disease out, as risk assessment may include PSA, clinical history, imaging tests and, when needed, a biopsy.
They also say not every case needs immediate surgery. Some low-risk tumours can be managed with active surveillance and regular follow-up. Surgery can cause urinary incontinence, but not in every patient, and many people improve over time with rehabilitation. Treatments can affect sexual function, but specialists say this does not mean the end of desire or intimate relationships.
Other myths they reject include the idea that no family history means no risk, and the claim that vasectomy causes prostate cancer. The scientific community has not proven a causal link between vasectomy and the disease. Age remains one of the main risk factors, and many diagnoses are made in men with no affected relatives.
The advice from urologists is consistent, regular check-ups from the age of 50, speaking to healthcare professionals about any concerns, and avoiding decisions based on viral content without scientific backing. They also recommend healthy habits such as regular physical activity and a balanced diet. Early detection remains one of the most effective tools for improving prognosis.
