In Children
In the US, about 2000 children and adolescents younger than 20 years of age are diagnosed with malignant brain tumors each year. Higher incidence rates were reported in 1985–94 than in 1975–83. There is some debate as to the reasons; one theory is that the trend is the result of improved diagnosis and reporting, since the jump occurred at the same time that MRIs became available widely, and there was no coincident jump in mortality. The central nervous system (CNS) cancer survival rate in children is approximately 60%. The rate varies with the type of cancer and the age of onset: younger patients have higher mortality.
In children under 2, about 70% of brain tumors are medulloblastoma, ependymoma, and low-grade glioma. Less commonly, and seen usually in infants, are teratoma and atypical teratoid rhabdoid tumor. Germ cell tumors, including teratoma, make up just 3% of pediatric primary brain tumors, but the worldwide incidence varies significantly.

Famous quotes containing the word children:
“Let us be different in our homes. Let us realize that along with food, shelter, and clothing, we have another obligation to our children, and that is to affirm their “rightness.” The whole world will tell them what’s wrong with them—out loud and often. Our job is to let our children know what’s right about them.”
—Adele Faber (20th century)
“Sometimes the children who are no problem to their parents should be looked at more closely. This is especially true if those children are extremely obedient and have few friends their own age. A good self-concept allows children to explore the world, risk engaging in conflict and failing. Children who play it safe by never disobeying or risking conflict may be telling you that they feel unqualified to face the world head-on.”
—Lawrence Kutner (20th century)
