Thank you for posting your query.
The most likely type of the tumour in this case is glioma
, which is the commonest primary tumour in the brain.
The tumour is likely to be malignant (cancerous), as the neurosurgeons have not removed the entire tumour and the patient is getting radiotherapy and chemotherapy
(these two treatments are often given for gliomas).
The long-term prognosis is generally not good, however it depends on the grade and staging of brain tumour
