Running Head: PSA Diagnostic Test 2 Prostate cancer is one of the most common cancers affecting men with > 1,100,000 new cases and 300,000 deaths worldwide each year (Tao et al, 2015). Being familiar with certain diagnostic test while we practice is very important. There are many test or screening tools that we can use to help diagnosis certain cancer in men and women. Prostate cancer is a major medical problem that needs immediate attention as the disease is indolent, shows prolonged latency in association with high morbidity and mortality (Tao et al, 2015). The test that I’m writing about is the PSA (prostate specific antigen). I will be explaining the purpose, how the test is conducted, sensitivity, predictive values, validity and reliability. PSA Test PSA test is a screening tool to detect prostate cancer in men mostly but does not diagnosis it. A PSA test can help catch the disease at an early stage when treatment is thought to be more effective and potentially has fewer side effects (The PSA Test and Screening. (n.d.). Prostate cancer has a lot of risk factors. Besides the genetic factors, family history and nutritional factors such as lack of enough vitamin D, high intake of calcium, obesity and high fat diets have been implicated as risk factors for prostate cancer (Tao et al, 2015). Prostate-specific antigen, or PSA, is a protein produced by normal, as well as malignant, cells of the prostate gland (National Cancer Institute, 2017). The test is conducted by drawing the patient’s blood and send to the lab.
