Childhood Brain Tumors Brain tumors are masses of cells that grow abnormally and uncontrollably within the brain. Primary brain tumors, whether malignant or benign, originate within the brain's tissues, while metastatic, or secondary, brain tumors represent tumors that have spread to the brain from a primary cancer originating outside the brain.
Metastatic tumors retain the primary tumor's tissue type.
