Often, early stages of prostate cancer do not cause symptoms. But, in some cases, men with prostate cancer may experience any of these problems:
-   A need to urinate frequently, especially at night
-   Difficulty starting urination or holding back urine
-   Weak or interrupted flow of urine
-   Painful or burning urination
-   Difficulty in having an erection
-   Painful ejaculation
-   Blood in urine or semen
-   Frequent pain or stiffness in the lower back, hips, or upper thighs

A man should speak with his doctor immediately if he is experiencing any of the above symptoms or if he is over 50 and has not had a recent prostate cancer screening. Men with a family history of prostate cancer, or who are African-American, should consider screening at an earlier age.
