Primary brain tumors are much less common than are secondary brain tumors, in which cancer begins elsewhere and spreads to the brain. Many different types of primary brain tumors exist. Each gets its name from the type of cells involved. Examples include: 1  Gliomas.2  These tumors begin in the brain or spinal cord and include astrocytomas, ependymoma, glioblastomas, oligoastrocytomas and oligodendrogliomas. 3  Meningiomas.any different types of primary brain tumors exist.

Benign brain tumors are usually defined as a group of similar cells that do not follow normal cell division and growth patterns and develop into a mass of cells that microscopically do not have the characteristic appearance of a cancer. Most benign brain tumors are found by CT or MRI brain scans. These tumors usually grow slowly, do not invade surrounding tissues or spread to other organs, and often have a border or edge that can be seen on CT scans. These tumors rarely develop into metastatic (cancerous or spreading) tumors.
