If your test shows you have a high PSA, that doesn't necessarily mean you have cancer. Your doctor will likely have you take another PSA test to make sure your level is higher than normal. Your doctor can also order other tests to help figure out why your PSA levels are high, such ...

The most common screening test for prostate cancer so often returns a false positive result that it's no longer recommended for men older than 70, and it's offered as a personal choice for younger men.
Each man was sent a single invitation by letter to attend a nurse-led prostate-check clinic appointment where the potential benefits and harms of having a PSA test were explained, and written informed consent was obtained. There was a second consent form completed after 24 h for all men who...
The main screening tool for prostate cancer is the PSA test, which measures levels of a protein calledprostate-specific antigen(PSA) in the blood. In the past, some experts have suggested that PSA testing caused more harm than good, saying it can lead to unnecessary biopsies and therapies for...
The PSA test alone can’t diagnose any disease. Elevated PSA levels do not always mean that you have prostate cancer or any other prostate problem. Let’s go into a more detail about the reasons why some men have a high PSA level. ...
Discordant prostate specific antigen test results despite WHO assay standardization. Int J Biol Markers. 2018 Aug;33(3):275-282. 摘要 介绍:总 PSA(t PSA)和游离 PSA(f PSA)是早期检 测前列腺癌最常用的生物标志物.尽管进行了标准化 工作,但目前使用的许多 PSA 检测方法可能产生不一 致的结果.在本...
Zlotta explained that repeat biopsy decisions are not based on a single PSA but that the new intervention might be a good idea before a repeat PSA test. Although PSA is a fairly sensitive marker for prostatic enlargement, it has poor specificity for prostate cancer. Nonmalignant conditions such...
Therefore, the decision to test for PSA levels in older men must take into account their relatively low risk of dying of prostate cancer, Kavoussi said. "Overall, it is known that about 10 percent of individuals diagnosed with prostate cancer succumb to the disease," he said. "In this olde...
Drawing on ethnographic fieldwork at a prostate cancer support group in western Canada, we seek to delineate the meanings the PSA test holds for prostate cancer survivors. For many men in the study, their PSA levels were seen to provide an objective indicator of the presence or absence of ...
