Prostate cancer screening may become significantly better with the use of a urine test, according to a new study just published in the journal Science Translational Medicine.

Prostate cancer screening is currently based on a blood test to detect PSA — prostate-specific antigen. But that test often produces false positives and leads to unnecessary biopsies. More than a million men in the U.S. undergo a prostate biopsy each year, and fewer than half of the patients actually have prostate cancer.

The new test appears to be better at detecting prostate cancer and determining which cancers will be aggressive.
