Neuro-oncology is a specialized branch of medicine that focuses on the study and treatment of tumors affecting the central nervous system, particularly the brain. Brain tumors can be either benign or malignant, and they arise from abnormal growth of cells within the brain tissue. The field of neuro-oncology encompasses a multidisciplinary approach involving neurosurgeons, neurologists, oncologists, radiologists, and other healthcare professionals working collaboratively to diagnose and manage brain tumors.
