A Better Prostate-Cancer Test?
May 10, 2016
(The Wall Street Journal) – The procedure done on Mr. Piazza’s tumor sample, called Prolaris by Myriad Genetics, is one of several new prostate-cancer tests that aim to reduce detection and treatment of tumors that are likely to be harmless while still spotting those that are lethal. That has been a daunting challenge in recent years. Routine screenings for prostate cancer, using blood tests for prostate-specific antigen, or PSA, have dramatically increased early detection of the disease. More than 99% of cases are curable today. Most of the cancers that prostate screenings find are so slow-growing they are effectively harmless, experts say. Still, because some cancers are aggressive and deadly, most men have opted for treatment with surgery or radiation despite a significant risk of incontinence or impotence.
