Childhood brain tumors are a group of diseases characterized by the abnormal growth of tissue in the skull. Children are diagnosed with brain tumors most often between the ages of three and eight, but can occur at any age.
Typically, pediatric brain tumors are discovered early because the brain regulates vital functions such as memory, learning, hearing, sight, smell and emotion, and when these vital functions are disrupted, signs are quickly apparent.
Brain tumors can be benign (without cancer cells) or malignant (contains cancer cells). Other than leukemia and lymphoma, brain tumors are one of the most common types of cancer to occur in children.
If your child has symptoms that may be caused by a brain tumor, his/her doctor may order a computed tomographic (CT) scan and/or a magnetic resonance imaging (MRI) scan.
Brain tumors are grouped according to their location, appearance and behavior of the tumor tissue. Infratentorial tumors are those that occur in the lower part of the brain.
