A brain tumor is a collection, or mass, of abnormal cells in the brain. Brain tumors can be cancerous or benign (noncancerous); however, any growth inside the skull, a restricted space, can cause problems.
Pediatric brain tumors are the most common form of solid tumors among children under the age of 15 and represent about 20% of all childhood cancers. Childhood tumors frequently appear in different locations and behave differently than brain tumors in adults. Treatment options vary and can be strongly influenced by the age of the child.
