This book focuses on topics of central nervous system (CNS) oncology, CNS cancer genomic, and stereotactic radiosurgery (SRS) for benign and malignant CNS tumors. CNS tumors are challenging cases to treat because of their closeness to critical normal tissues such as brainstem and optic apparatus. Modern SRS has been developed to solve the practical challenges of CNS cases. This book discusses in details the use of advanced robotic SRS to treat complex CNS cases as a primary modality and in re-irradiation, and selected topics on modern ultra-precision radiotherapy treatment planning and delivery to obtain good results. This book belongs to a series that covers in depth each organ site of cancer to find the best in treatment, public health and the arts that nourish us in health and sickness. This book may interest practitioners and researchers of oncology and public health.
