* The cerebrum is the largest part of the brain and is made up of the right and left cerebral hemispheres. It allows us to see, feel, think, speak and move. The right side of the brain controls the left side of your body and vice versa.

* The cerebellum is located in the back of the brain and controls balance and coordination.

* The brain stem controls our vital bodily functions, like heartbeat, breathing and reflexes. It connects the brain to the spinal cord.

The skull is hard and canâ t expand, so as a tumour grows the pressure within the skull can damage or destroy delicate brain cells. Brain cancer can involve either the neurons or the glial cells. Most adult cancers start in the glial cells and are called astrocytomas or gliomas. Rarer adult brain tumours include oligodendrogliomas and lymphomas. Childhood primary brain tumours account for about 15% of all cases. They include medulloblastomas (which often start in the cerebellum), ependymomas (which tend to start in the cavities of the brain), and astrocytomas (which start in the cells that support the neurons). ...
