Most early prostate cancers don’t cause any urinary problems—so if a man has trouble peeing, it’s probably not cancer, and if he has no symptoms at all, he could still have cancer.

Urinary symptoms and prostate cancer—the misconception that may be preventing earlier presentation and better survival outcomes

Narrative Review

2022 Aug 4

This study says that having trouble urinating doesn’t mean you have prostate cancer — in fact, men with bigger prostates usually have harmless enlargement, while prostate cancer often happens in smaller prostates and has no symptoms at first. So, don’t wait for urinary problems to get checked.

Similar Assertions

Prostate cancer grows on the outside of the prostate, while urinary problems come from swelling in the middle—so one doesn’t cause the other.

Men who wait until they have trouble peeing to get checked for prostate cancer are much more likely to find out their cancer is already spread, compared to men who get tested even if they feel fine.
