How to Interpret PSA Numbers

A prostate-specific antigen (PSA) is a protein found in prostate cells. Doctors perform PSA tests to screen for prostate cancer and to monitor patients who have recently had it. A high PSA level or a rapid increase in PSA level indicates a higher risk of developing prostate cancer. However, since many factors can raise PSA levels, such as urinary tract infections or prostate inflammation, PSA tests are not infallible. In fact, some organizations do not recommend routine PSA testing, since the test can provoke anxiety and false-positive results. In addition, many prostate cancers do not require treatment.

Instructions

• 1

  Discuss your PSA levels with your doctor. If possible, compare your results with your PSA levels of previous years. According to the National Cancer Institute, "there is no specific normal or abnormal PSA level." However, significant changes from year to year may indicate the risk of cancer, according to the Mayo Clinic. Your doctor will also consider your age and the size of your prostate.

• 2

  Tell your doctor if you have any symptoms that may indicate prostate cancer, such as urinary hesitation or pain, lower back pain, unintentional weight loss, bone pain, abdominal pain or lethargy. If you display symptoms of prostate cancer, your doctor may order a prostate biopsy.

• 3

  Stay calm. High PSA levels do not necessarily indicate prostate cancer. According to the National Cancer Institute, only 25 to 35 percent of men who have prostate biopsies as a result of elevated PSA levels are diagnosed with prostate cancer.
