Virginia Tech Sep 9 2025 Glioblastoma is a devastatingly effective brain cancer. Doctors can cut it out or blast it with radiation, but that only buys time. The cancer has an insidious ability to hide enough tumor cells in tissue around the tumor to allow it to return as deadly as ever. Patients diagnosed with glioblastoma survive for an average of 15 months. What's needed is a better way of identifying those hidden cancer cells and predicting where the tumor might grow next. Jennifer Munson
