Does anyone know: In which year was the first brain tumor discovered?
According to this source and this, brain cancer was first discovered in 1873 and brain tumor before that. We can't say for sure when the first case of brain tumor occurred because it may have been originated in the prehistoric times. Since no data was recorded in those times, it isn't certain to say when and where the first case of brain tumor occurred.
It’s not that hard to answer the question of who discovered brain cancer – this breakthrough is credited to Gupta Longati, a Russian scientist, who discovered the disease in 1873.
