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.

Brain tumor - primary - adults. A primary brain tumor is a group (mass) of abnormal cells that start in the brain. Primary brain tumors include any tumor that starts in the brain. Primary brain tumors can start from brain cells, the membranes around the brain (meninges), nerves, or glands. Tumors can directly destroy brain cells. They can also damage cells by producing inflammation, placing pressure on other parts of the brain, and increasing pressure within the skull. The cause of primary brain tumors is unknown. Radiation therapy used to treat brain cancers increases the risk of brain tumors up to 20 or 30 years later.
