New Test May Detect More Prostate Tumors

A blood test under development may detect more prostate tumors than the current test, and could eliminate thousands of unneeded biopsies, reports the Washington Post. The test, EPCA-2, is being developed by Oconome, Inc. (Seattle) and a research team at Johns Hopkins University (Baltimore). The current test, PSA, produces a lot of false positives, and 80% of the biopsies that result from it come back negative.
