Can an EEG (electroencephalogram) detect brain tumors?

In brief: No

Eeg can show presence of seizure brain wave activity.
These seizure brain activity can be caused by different conditions such as metabolic abnormality, lack of blood supply to brain cells, medication, epilepsy, brain tumor related, etc. It analyzes the brain "function" not the anatomy thus it can't detect brain tumor specifically. Mri needs to be done to detect brain tumors. Discuss with your md.

In brief: Sometimes

Yes, if the tumors are causing focal irritability or otherwise disrupting brain function in the region where they are located.
That being said, eeg is often not as sensitive as imaging (ct/mri).

In brief: No

Imaging studies such as an MRI or CT are used not EEGs.
