How the brain works

What is brain tumours?

How the brain worksThe brain is the control centre of the body. Everything we do, think or feel involves the brain. It controls the body by sending electrical messages along nerve fibres. The nerve fibres run out of the brain and join together to make the spinal cord. This cord of nerve fibres runs down the middle of the spine. And the nerve fibres then spread out to all areas of the body. Together, the brain and spinal cord form the central nervous system. A clear fluid circulates around the brain and spinal cord. It is called cerebrospinal fluid or CSF for short.The brain is made of nerve cells called neurones. There are billions of these neurones. Also in the brain are other types of cells that support the neurones. These are called glial cells. Glial cells can become cancerous and grow into a brain tumour.

Types of primary brain tumours?

There are many types of primary brain tumours. They are generally named after the type of brain cells that they contain.
The most common type is glioma, which is a tumour that grows from glial cells. These are cells that support the nerve cells of the brain. Over half of all primary brain tumours in adults are gliomas.5
Brain tumours are graded according to how quickly they grow (low grade is the slowest growing).5
