This is a timeline of brain cancer, describing especially major discoveries, advances in treatment and major organizations.

Big picture

Year/period	Key developments
19th century	First record on discovery of brain cancer. First surgery for a brain tumor is performed in this century.
1920s	Electroencephalograms (EEG) in humans develop as a method to record activity in the brain.
1970s	Computed tomography (CT) scanning is developed and provides first clear image of brain tumors. First promising chemotherapy for glioma is developed. Radiation is established as standard treatment for glioblastoma.
1980s	Magnetic resonance imaging is introduced and gains widespread use. It eventually replaces CT scanning as The Primary imaging tool for brain tumors. Gamma knife therapy is introduced for treating brain tumors.
1990s	Advances in chemotherapy and radiation increases survival for patients. Classification for brain tumors unifies into one universal system.
2000s	The Cancer Genome Atlas project launches.
2010s	Today, cancer immunotherapy is being actively studied. Primary brain tumors occur in around 250,000 people a year globally, making up less than 2% of cancers. Figures for incidence on brain cancer show predominance in more developed countries.

1926	Development	Percival Bailey and Harvey Cushing introduce the term glioblastoma multiforme, based on the idea that the tumor originates from primitive precursors of glial cells (glioblasts), and the highly variable appearance due to the presence of necrosis, hemorrhage and cysts (multiform).
1930	Development	Astroblastoma, a rare glial tumor, is first described.
1936	Development	American neurophysiologist William Grey Walter first identifies the association between localized slow waves on electroencephalograms and tumors of the cerebral hemispheres. The term "delta waves" is introduced by Walter.

1938		Gliomatosis cerebri (a rare primary brain tumor) is first described.

1945	Development	Subependymoma (a rare form of ependymal tumor) is first described.
1955	Development	Choroid plexus papilloma (a rare benign neuroepithelial intraventricular WHO grade I lesion found in the choroid plexus) is first reported.
1958	Treatment	Dexamethasone is first synthesized. To date it remains the most favorable [...] for brain cancer patients.

1973	Organization	American Brain Tumor Association is founded as a nonprofit organization. It provides support services and programs to brain tumor patients and their families, and funds brain tumor research.	Chicago, Illinois, US
1975	Treatment	Radiation therapy becomes standard treatment for glioblastoma, showing it extends median survival from 3 months to about 9 months in patients.
1978	Development	Researchers at EMI Laboratories obtain the first Magnetic resonance imaging (MR) of a human brain.	UK
1979	Development	Pleomorphic Xanthoastrocytoma (a rare tumor located throughout the supratentorial compartment in the brain) is first described.
1982	Development	Central neurocytoma (an extremely rare, ordinarily benign intraventricular brain tumour), is first described.
1988	Organization	The Children's Brain Tumor Foundation is established. It funds research in brain cancer.	New York City, US
1993	Discovery	Large analysis shows that adding chemotherapy to radiation therapy helps patients with surgically treated malignant gliomas live longer compared to radiation therapy alone.
1993	Development	World Health Organization develops universal system for classifying brain tumors with aims at improving communication and translate research findings.
1994	Development	The first study of the human brain at 3.0 T is published.
1994	Development	US National Cancer Institute establishes brain tumor research networks for adults and children, comprising brain cancer experts from academic centers who collaborate to evaluate novel therapies against brain cancer.	United States
1996	Discovery	Researchers at University of Washington find that brain cancer is related to low levels of protein MGMT.	United States
1996	Development	Giant cell ependymoma (an uncommon neuroepithelial tumor located in the central nervous system) is first described.
