For a number of years men over 50 years of age have been urged by their doctors to get a PSA blood test to help diagnose the condition of their prostate. Very recently the American Cancer Society recommended changing the emphasis from it would be a good idea for men over 50 to get a PSA test to consider the potential risks of treatment before making the decision to get a PSA test to screen for prostate cancer. The reasoning supporting this change of emphasis was based on the trade off between the negative side effects of PSA screening versus the positive benefits of avoiding the test. For example a slightly high PSA blood test may detect prostate cancer, but it can be a false positive. Conversely men with apparently normal PSA scores actually have had cancer, but the test indicated that they did not have cancer. The high PSA score typically was followed by a biopsy and treatments that had negative side effects that included urinary incontinence and impotence.
For these reasons the American Cancer Society made the recommendation that men who do not have special risks of prostate cancer should take counsel with their doctors, in order to reach an informed decision about getting screened for prostate cancer. The American Society of Clinical Oncology, which represents cancer specialists, including those treating prostate cancer patients, is supporting the Cancer Society guidelines. This is good news for senior men who are about to reach the age when they need to be concerned about the health of their prostates.
