Pediatric brain tumors are abnormal growths of cells in the brain or spinal cord that occur in children. These tumors can be benign (non-cancerous) or malignant (cancerous) and may affect a child's development, coordination, and overall health. Common types include medulloblastomas, gliomas, and ependymomas. Symptoms of pediatric brain tumors can vary but often include headaches, nausea, vision problems, and changes in behavior. Diagnosis typically involves imaging tests like MRI or CT scans, followed by treatment options such as surgery, radiation therapy, or chemotherapy, depending on the tumor's type and location.
