On the list of dreaded medical tests, a prostate biopsy probably ranks fairly high. The common procedure requires sticking a needle into the prostate gland to remove tissue for assessment. Thousands of men who undergo the uncomfortable procedure, prompted by a positive PSA (prostate -specific antigen) test, ultimately don’t require cancer treatment. Today, scientists report progress toward minimizing unnecessary biopsies: They have identified the molecules likely responsible for the scent of prostate cancer, which could be detected by chemically “sniffing” urine.
