 Hello, this is State Health Officer, Dr. Don Williamson. While some men with prostate cancer experience changes in urinary or sexual function, it's important to remember that many cases are first detected by a doctor during a routine checkup. If you're 50 years of age or older, ask your family physician about a prostate cancer screening during your annual physical. Men who are at higher risk for prostate cancer are encouraged to begin testing at age 45. And if you experience any symptoms, you should contact your physician as soon as possible, regardless of age.
