In this week’s installment of Medical Discovery News, UTMB’s Norbert Herzog and David Niesel report that scientists hope to be able to identify key mutations of genes in each cancer type. “We’re talking about the potential of a simple blood test to reveal if and what mutations have occurred in your cells and whether you face a risk for cancer. If you do, you could then undergo regular testing to catch the disease early on.” MDN airs locally at 10 a.m. Saturday on KUHF.
