Timeline of brain cancer

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.[1] First surgery for a brain tumor is performed in this century.[2]
1920s	Electroencephalograms (EEG) in humans develop as a method to record activity in the brain.[3]
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.[4]
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.[4]
1990s	Advances in chemotherapy and radiation increases survival for patients. Classification for brain tumors unifies into one universal system.[4]
2000s	The Cancer Genome Atlas project launches.[4]
2010s	Today, cancer immunotherapy is being actively studied.[5] Primary brain tumors occur in around 250,000 people a year globally, making up less than 2% of cancers.[6] Figures for incidence on brain cancer show predominance in more developed countries.[7]
