About Brain Tumors and Central Nervous System Tumors
Brain tumors in children occur in the central nervous system (CNS) and spinal cord. Together, these important organs control functions necessary to sustain life, such as breathing, heart rate, movement, thinking and learning. Important substances produced in the brain stimulate and control many other organs in the body. When pediatric brain tumors develop, they have many unique properties and symptoms.
In general, brain tumors tend not to “metastasize” or spread to distant areas of the body outside the brain or spinal cord. They can recur locally, and they can spread to other areas of the central nervous system.
There are several different types of brain tumors. Collectively, they comprise nearly 20% of childhood cancers diagnoses.
