In July, the World Health Organization released its updated classification of Tumors of the Central Nervous System. The last update was in 2016. The update reflects the increasing role of molecular biomarkers in tumor characterization -- a change that has major implications for how we diagnose and treat patients with brain and spinal cord tumors. Joining us today to help us understand these changes is Dr. Lynne Taylor. Dr. Taylor is a professor of Neurology and Oncology at the University of Washington and co-director of the Alvord Brain Tumor Center at University of Washington Medical Center. Dr. Taylor was interviewed by ANA Investigates producer and neuro-oncologist, Dr. Doug Ney. Series 2, Episode #10
