What percentage of ependymoma brain tumors are benign?

What percentage of ependymoma brain tumors are benign?

0%: All ependymoma brain tumors are technically malignant, meaning the cells are cancer and can grow into the surrounding brain tissue. However, most of these tumors (over 90%) are curable because the tumor is confined to one area, is slow-growing, and can be removed by surgery. Sometimes radiation alone is used for slow-growing brain ependymomas if surgery can't be performed. ...Read more

Can an EEG (electroencephalogram) detect brain tumors?

Can an EEG (electroencephalogram) detect brain tumors?

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. ...Read more

Is pilocytic astrocytoma a tumor of cerebellum?

In theory anywhere: In theory, it could happen anywhere in the brain, but most juvenile pilocytic astrocytomas are in the supratentorial brain (outside of the posterior fossa). Posterior fossa tumors are typically ependymoma, medulloblastoma in kids. Jpa's don't happen in adults (adults get lgg's, or who ii low grade gliomas..Just almost never who i tumors). Most stem lesions are not jpa's, but they happen too. ...Read more

S+s of end stage primary brain cancer, (aa iii) r medial temporal lobe, diffuse numerous cells. Growing!/brainstem and posterior temp./basal ganglia?

Ask for more info: Signs and symptoms can vary greatly with any 'end-stage' cancer. Things like if it has spread to other organs, impacting functional status and alertness (sleeping more, in bed most of the time), causing pain/seizures, and so on.
