Abstract
This article, the third in a three-part series, addresses the complex issues surrounding screening for prostate cancer. The purpose of screening in health care is discussed and the advantages and disadvantages of the various screening tests for the early detection of prostate cancer are outlined. The use of one specific technique to screen men for prostate cancer is questioned. It is suggested that several techniques should be used to assess risk in detail. Employing only one technique, for example prostate specific antigen, may result in men undergoing unnecessary surgery or inappropriate treatment. Nurses have a professional duty to ensure that they are aware of the advantages and disadvantages with respect to screening men for cancer of the prostate. Patients' must be in possession of the facts before they make important decisions about their health. In order to reduce harm the nurse can become the patient's advocate and act in such a way as to safeguard and promote the patient's interests.
