A PSA test measures your blood level of prostate-specific antigen (PSA), a protein that your prostate gland produces, to help screen for prostate cancer.
The U.K. Cluster Randomized Trial of PSA Testing for Prostate Cancer (CAP) trial was a primary care–based, randomized, controlled trial in which 419,582 men 55 to 69 years of age were assigned ...
‘The test is usually just a single vial of blood taken from the inner elbow,’ says Paul Sayer, founder of Prost8 UK, explaining that a PSA reading above 4ng/ml in men over 60 (and 3ng/ml for ...
The PSA test is a simple, inexpensive blood test, administered by a primary care or family practice doctor to measure the level of a substance called prostate-specific antigen (PSA), which is ...
The PSA test for prostate cancer is surprisingly controversial. Many experts, in fact, now recommend against the test for most men, saying that the cancers it detects are often relatively harmless ...
Mean time to PSA elevation was 3.4±5.5 years, and mean elevation in PSA was 0.33±0.28 ng ml−1. Each patient's PSA was undetectable after being repeated, and no patient went on to unnecessary ...
A simple blood test would allow doctors to measure levels of a protein called prostate-specific antigen, or PSA. If those levels were deemed too high, it was considered a possible sign of cancer.
If 1,000 men get PSA screening (cost: roughly $40), 240 will be told their PSA level suggests cancer might be present. Next step: a biopsy, in which a needle, usually inserted through the rectum ...
The PSA test is an imperfect way to screen men for prostate cancer. But until recently, it was seen as the best option available. The test measures the amount of prostate specific antigen, or PSA ...
The purpose of this study was to determine the incidence of prostate cancer in patients who have an elevated referral prostate-specific antigen (PSA), which subsequently falls to within their ...
Middle-aged men know the story: the PSA (prostate-specific antigen) test is an essential early-warning system for cancer. Elevated PSA levels mean cancer, which in turn means you should probably ma… ...
The test has been routinely used as a screen for prostate cancer starting in middle age since the 1990s. The precise level of PSA in the blood or patterns of PSA change deemed suspicious vary ...
