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 ...

PSA levels usually increase with age, so the older you are the higher you can expect your PSA levels will be. PSA levels also vary depending on the size of your prostate.

Patients with an elevated prostate-specific antigen (PSA) level are known to have an increased risk of harbouring prostate cancer. 1 However, recent work by Eastham et al. 2 has shown that a ...

The PHI test, which considers total PSA levels along with two specific types of PSA proteins, is more sensitive than the PSA test alone, says Dr. David Penson, chair of urologic surgery at the ...

In the Prostate Cancer Prevention Trial, prostate cancer was detected in 15.2% of men whose PSA levels remained below 4.0 ng per milliliter throughout the 7-year trial and in 6.6% of men with a ...

Serum PSA level was positively correlated with high-grade disease (OR for Gleason scores ≥7, 2.10 per unit increase in serum PSA; 95% CI 1.66 to 2.65). Conclusion ...

Medically reviewed by Archana Sharma, DO A PSA test measures the level of prostate-specific antigen (PSA), a protein that your prostate gland produces, in a sample of your blood. PSA levels can ...

What's more, the test isn't terribly accurate. At least half of all men whose PSA levels are over 4 don't have cancer. And some men with prostate cancer have perfectly normal PSA readings.
