Biomarkers: what are they and how are they useful in the diagnosis and treatment of prostate cancer? On this episode of the JNM Podcast, our panel of experts explores what they call a "liquid biopsy:" using biomarkers shed by cancer cells into the bloodstream to gain vital insights about the disease and its progression, identify candidates who would benefit from certain therapies, and monitor the effectiveness of treatments. Listen now to learn more about the clinical use of biomarkers. Our host Ken Herrmann, MD, is joined by Jake Berchuck, MD, Alexander Wyatt, PhD, and Rana McKay, MD.
