Prostate cancer is the second most common—and deadly—type of cancer among men, behind lung cancer. Prostate cancer can be inherited, so a man whose brother or father had prostate cancer has a 50 percent greater risk of developing the same cancer. It’s also more common among African American men and young men can develop it as well. In fact, prostate cancer in men under 50 is often the most aggressive and more difficult to treat. Men in their 40s should pay close attention to any changes in their health. Frequent urination, pain or burning during urination, blood in your urine, and weak urine flow should be reported to your doctor as soon as possible. Learn more about prostate cancer.
