Medical experts do not know exactly how to prevent prostate cancer, but they are studying many different factors. They do know that not smoking, maintaining a healthy diet, staying physically active, and seeing your doctor regularly contribute to overall good health.

Your doctor can check you for prostate cancer before you have any symptoms. Prostate cancer screening can help doctors find and treat cancer early. But studies so far have not shown that screening tests, such as the PSA test, reduce the number of deaths from the disease.
Neither of the screening tests for prostate cancer is perfect. Most men with mildly elevated PSA levels do not have prostate cancer, and many men with prostate cancer have normal levels of PSA.
You may want to talk with your doctor about the possible benefits and risks of being screened. The decision to be screened, like many other medical decisions, is a personal one. You should decide after learning the pros and cons.

If you have a symptom or test result that suggests prostate cancer, your doctor must find out whether it is due to prostate cancer or to some other cause. Your doctor will ask about your personal and family medical history. You will have a physical exam. You may have lab tests. Your visit may include a digital rectal exam (DRE), a urine test to check for blood or infection, and a blood test to measure PSA (prostate-specific antigen) level in order to make a diagnosis of prostate cancer.
