The American Cancer Society suggests a yearly prostate screening for all men age 50 and over. However, select circumstances may warrant screenings beginning at an earlier age. These include:  Age 40 for men with more than one first-degree relative (son, brother, or father) who had prostate cancer before age 65. Age 45 for men with a single first-degree relative who had prostate cancer before age 65. Age 45 for African American men due to carrying a higher risk of prostate cancer. Problems associated with your bladder, urethra, and penis can all potentially have ties to prostate problems. Due to the proximity of the prostate to these systems it can grow and press against them causing dysfunction. With prostate issues you may experience the following:  Slow or weak urine streams Difficulty urinating Frequent urination at night Burning urination Blood in your urine Difficulty getting an erection Painful ejaculation Lower back pain If you have any urinary symptoms, a variety of ailments may be responsible that a DRE alone cannot diagnose. Also, a DRE is just one of several tests your doctor may use to determine the health of your prostate.  Your doctor may order a trans rectal ultrasound (TRUS) to check for suspicious tissues inside of your rectum. A biopsy may also be necessary to confirm or rule out cancer. Your doctor can order a laboratory test to check your PSA levels (a specific protein found in your prostate) in the event of prostate abnormalities. Most doctors conclude a PSA level of 4ng/ml or lower is considered normal.  PSA levels can cause false positive or false negative results. The Unites States Preventive Task Force advises against prostate screening with PSA levels due to these risks.  Ejaculation (recent sexual activity), prostate infection, digital rectal examination, and bike riding (due to pressure on the prostate) can cause elevations of PSA. Those without prostate symptoms and elevated PSA may require repeat testing after two days. Repeat elevated PSA levels may warrant a DRE and/or biopsy...
