It depends on the brain tumor.  There are lots of different types (and actually, not every tumor is a cancer, so the better word to use is 'neoplasm').

Different tumors begin with different cells going wrong and growing out of control.  A gangliocytoma is a neoplasm of the neurons, and there are tumors that originate from neuroectodermal tissue or have mixed origins (medullablastomas, retinoblastomas, lots more).  

There are also a lot of other types of cells in the brain and any of them can become neoplastic--there are glia (support cells) like astrocytes, oligodendrocytes, ependymal cells and the meninges (the lining of the skull and brain cavities)--they can become astrocytomas, oligodendrogliomas, ependymomas, and meningiomas.  You can also have tumors of the cells that sheathe the nerves--Schwannomas or neuromas and tumors of different structures like the pituitary or pineal glands--craniopharyngiomas and pineoblastomas/pineocytomas.  You can even have primary central nervous system (CNS) lymphoma, which is not of brain tissue at all, really.

That's just the tip of the iceberg.  Basically, if you have a cell type in mind, it's probably caused a tumor in its time.
