Prostate Cancer Does Not Discriminate
Getting screened for prostate cancer is not glamorous, it’s not enviable, and it’s certainly not something young men dream about. However, it is necessary to get one in order to prevent serious health risks. Here is some information on what you need to know about the PSA test.
What is the PSA Test?
PSA , or prostrate specific antigen, is a protein that is produced by the cells in the prostrate gland. The level of PSA in the blood is often elevated in men with prostrate cancer. Men who report prostate symptoms are subject to PSA testing to determine what is causing their problem. The test is done in combination with a digital rectal exam (DRE).
Who Should Get a PSA Test?
Traditionally, doctors have recommended yearly PSA screening beginning at the age of 50. Some recommended that men at a higher risk, including African American men and those with prostate cancer in their family history, begin the screening at 40 or 45. However, due to recent revelations about the potential benefits and harms associated with the screening, some organizations have begun to argue that a man who is considering testing should be informed in detail about the possible outcomes. The test is covered by Medicare and most private insurers.
What Are the Possible Harms or Limitations of a PSA Screening?
Early prostate cancer protection may not reduce the risk of dying from the disease. PSA screenings may detect small tumors that grow too slowly to become life threatening. Detecting these tumors is called an “over diagnosis” and treating them is called “over treatment.” Over treatment can expose meant to harmful side effects of the treatment, including urinary incontinence, erectile dysfunction and problems with bowel function.
Tests may give false positives or false negatives. A false positive test can occur if a man’s PSA level is high.but no cancer is present. This is the case with most men; only about 25% of men who have an elevated PSA level test positive for cancer.
What Should You Do If Your Screening test shows a high PSA level?
Usually doctors recommend that a man showing an elevated PSA level have another screening to confirm the results. If the level is still high, the doctor will probably suggest that the man continue with DREs and PSA tests at regular intervals.
If the levels continue to go up, or if a lump is detected, doctors will order additional tests. If cancer is suspected, a doctor will recommend that the patient have a prostate biopsy to determine the nature of the problem.
The largest of research studies done on prostate and cancer screening was conducted by the Prostate, Lung, Colorectal, and Ovarian (PLCO) Unit. Evidence showed that most men who were treated for prostate cancer would not have been detected without the screening.
