Brain Tumor Webinar Series Continues tonight Sunday 5/24/2020 at 7PM Eastern Dr Orringer invented a new way for the surgeon to tell the difference between normal brain tissue and tumor tissue as well as what grade of tumor it, quickly while still in the surgery. He also specializes in brain mapping and tumors of the speech and movement areas of the brain. He is involved in several brain tumor clinical trials. Should be a very interesting webinar!
