PSA速度： 从研究看，人随着年龄的增加PSA每年增长小于0.75 ng/ml，一般不会患有前列腺癌；大于0.75 ng/ml则患前列腺癌的危险性增加。据研究对前列腺 ...

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 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 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 ...

Early cancer detection significantly improves treatment success and survival rates through various screening methods. Regular ...

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.

How do I request one? What are the downsides to taking one? Are there better alternatives? We answer all these questions and more ...

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 ...

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 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 ...

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 ...
