New Blood Test Sharpens Prostate Cancer Diagnosis

A new blood test - the six-gene molecular diagnostic test - used in combination with conventional prostate-specific antigen (PSA) screening sharply increases the accuracy of prostate cancer diagnosis, accurately detecting prostate cancer more than 90 percent of the time.

The new test could eliminate tens of thousands of unneeded, painful, and costly prostate biopsies annually, according to a study led by researchers at Dana-Farber Cancer Institute.

Earlier studies suggest that the conventional PSA test is 60-70 percent accurate in detecting cancer.
