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:
“Every milestone of a firstborn is scrutinized, photographed, recorded, replayed, and retold by doting parents to admiring relatives and disinterested friends. . . . While subsequent children will strive to keep pace with siblings a few years their senior, the firstborn will always have a seemingly Herculean task of emulating his adult parents.”
—Marianne E. Neifert (20th century)
“I don’t believe that children can develop in a healthy way unless they feel that they have value apart from anything they own or any skill that they learn. They need to feel they enhance the life of someone else, that they are needed. Who, better than parents, can let them know that?”
—Fred Rogers (20th century)
