I had a PSA test — it's elevated. Does this definitely mean something is wrong with the prostate or cancer? And what else could it indicate?

PSA is a protein produced by the prostate gland, and the test is used to suspect its diseases, while normal ranges depend on age. In a new study, elevated PSA was found in 3.5% of 5,325 men and was more common with age: men aged 50–69 accounted for 73% of such cases, as well as in men with higher BMI and obesity. Besides prostate diseases, men with elevated PSA more often had erectile dysfunction and lower urinary tract symptoms, such as frequent urges or a weak stream. Therefore, elevated PSA is not a verdict, but a reason to discuss with a doctor both the condition of the prostate and such symptoms. The association is strong, but it is not yet clear what is cause and what is effect, and the final diagnosis is made by a doctor after further examination.
