New prostate cancer test pinpoints disease better than PSA option, study finds

Mount Sinai urology chair Dr. Ash Tewari joins'Fox News Live' to discuss the PSA test designed to catch the'silent killer.' A new means of prostate cancer screening could emerge as an alternative to the PSA test, which has long been the first-line option. Using machine learning, a form of artificial intelligence, Swedish researchers analyzed urine samples from more than 2,000 men with prostate cancer, along with a control group. They determined that the simple, non-invasive urine test was able to detect biomarkers of prostate cancer with a high degree of accuracy -- and could also determine the grade (stage) of the disease. The results were published in the journal Cancer Research.
