Method for detecting the presence or risk of prostate cancer by detecting products of psa or klk2

摘要

The present invention discloses a method for detecting the presence or diagnosing the risk of cancer, especially prostate cancer, either before or after the onset of clinical symptoms, by detecting a level or functional activity of an aberrant expression product of a gene selected from PSA or KLK2, which correlates with the presence or risk of the cancer. The invention further encompasses the use of agents that modulate the level or functional activity of such an aberrant expression product for treating or preventing cancer, especially prostate cancer.
