| ==Overview== | | ==Overview== |
| Epidemiological record suggests a growing share each year of infants and children in the United States affected by brain tumors.
| | In 2012, the prevalence and incidence of brain tumors were 148,818 and 6.4 per 100,000 persons per year respectively. The case-mortality rate of brain tumors is 4.4 per 100,000 persons per year. Patients of all age-group develop this cancer. Males are more affected with gliomas than females. Females are more affected with meningiomas. It usually affects individuals of the caucasian race. African Americans are less likely to develop this cancer. |

| | ==Epidemiology and Demographics== |
| | Brain tumors account for 85% to 90% of all primary central nervous system (CNS) tumors. |
| | ===Prevalence=== |
| | *In 2012, there were an estimated 148,818 people living with brain and other nervous system cancer in the United States.<ref name="seer">National Cancer Institute. Surveillance, Epidemiology, and End Results Program 2015.http://seer.cancer.gov</ref> |

|
| | ===Incidence=== |
| | *Available registry data from the Surveillance, Epidemiology, and End Results (SEER) database for 2012 indicate that the combined incidence of primary CNS tumors in the United States is 6.4 per 100,000 persons per year, with an estimated mortality of 4.4 per 100,000 persons per year. These rates are age-adjusted and based on 2008-2012 cases and deaths. |

| * SEER: The incidence rate of primary malignant brain and central nervous system tumors (excluding lymphomas, leukemias, tumors of pituitary and pineal glands, and olfactory tumors of the nasal cavity) for the years 2004-2008 is 6.5 cases per 100,000 person–years. This rate is higher in males (7.7 per 100,000 person–years) than females (5.4 per 100,000 person–years). <ref> Howlader N, Noone AM, Krapcho M, Neyman N, Aminou R, Waldron W, Altekruse SF, Kosary CL, Ruhl J, Tatalovich Z, Cho H, Mariotto A, Eisner MP, Lewis DR, Chen HS, Feuer EJ, Cronin KA, Edwards BK (eds).

| * SEER: The incidence rate of primary non-malignant brain and central nervous system tumors for the years 2004-2008 is 12.8 cases per 100,000 person–years. In contrast to malignant brain and central nervous system tumors, this rate is higher in females (15.3 per 100,000 person–years) than males (10.1 per 100,000 person– years).
| |
| * ACS(American Cancer Society): An estimated 22,910 new cases of primary malignant brain and central nervous system tumors are expected to be diagnosed in the United States in 2012 (12,630 in males and 10,280 in females). This represents 1.4% of all primary malignant cancers expected to be diagnosed in the United States in 2012.<ref> Siegel R, Naishadham D, Jemal A. Cancer Statistics, 2012.

| * IARC(International Agency on Research on Cancer): The worldwide incidence rate of primary malignant brain and central nervous system tumors in 2002, age–adjusted using the world standard population, is 3.7 per 100,000 person–years in males and 2.6 per 100,000 person–years in females. This represents an estimated 108,277 males and 81,305 females who were diagnosed with a primary malignant brain tumor in 2002, an overall total of 189,582 individuals. The incidence rates are higher in more developed countries (males: 5.8 per 100,000 person–years; females: 4.1 per 100,000 person–years) than in less developed countries (males: 3.0 per 100,000 person–years; females: 2.1 per 100,000 person–years). <ref> Ferlay J, Bray F, Pisani P and Parkin DM.

| ===Brain tumors in infants and children===
| |
| In 2000 approximately 2.76 children per 100,000 will be affected by a [[brain tumor|CNS tumor]] in the United States each year. This rate has been increasing and by 2005 was 3.0 children per 100,000. This is approximately 2,500-3,000 pediatric brain tumors occurring each year in the US. The tumor incidence is increasing by about 2.7% per year.
| |
| The [[Central Nervous System|CNS]] Cancer survival rate in children is approximately 60%.<ref>[http://seer.cancer.gov/publications/childhood/cns.pdf See Table 11.2 Survival Rate]</ref> However, this rate varies with the age of onset (younger has higher mortality) and cancer type.
| |
| | |
| 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 [[ATRT|atypical teratoid rhabdoid tumor]].<ref>[http://www.childhoodbraintumor.org/InfantileBrainTumors.html ''Infantile Brain Tumors'' by Brian Rood for The Childhood Brain Tumor Foundation] (accessed July 2007)</ref>
