• 110 men would be diagnosed with prostate cancer. About 50 of these men would have a complication from treatment, including erectile dysfunction in 29 men, urinary incontinence in 18 men, severe cardiovascular events in 2 men, deep vein thrombosis or pulmonary embolism in 1 man, and death due to the treatment in less than one man. Limitations to PSA Testing for Prostate Cancer Screening
• Detecting prostate cancer early may not reduce the chance of dying from prostate cancer : Finding tumors, however, does not necessarily reduce a man’s chance of dying from prostate cancer. Some tumors found through PSA testing grow so slowly that they are unlikely to threaten a man’s life. Detecting tumors that are not life threatening are called “overdiagnosis,” and treating these tumors is called “overtreatment”; Thus, exposing men to the unnecessary complications and harmful side effects of treatments for early prostate cancer, including surgery and radiation therapy. Also, early detection of cancer may not help a man who has an aggressive or malignant tumor that probably has spread to other areas of the body before detection. • False-positive or False-negative results of PSA test : A false-positive test result occurs when a man’s PSA level is elevated, but no cancer is present. Most men with an elevated PSA level turn out not to have prostate cancer; only about 25 percent of men who have a prostate biopsy due to an elevated PSA level have prostate cancer (Barry, 2001). A false-negative test result occurs when a man’s PSA level is low even though he has prostate cancer. False-negative test results may give a man, his family, and his doctor false assurance that he does not have cancer, when he may, in fact, have cancer that requires treatment.
Conclusion PSA testing can help catch prostate cancer at an early stage. However,
