What is a glioma?

A glioma is a type of brain tumour that starts in the brain (primary brain tumour). More than half of all primary brain tumours are gliomas.

These tumours are made up of cells that look similar to a type of cell called glial cells. Glial cells are the supporting cells in the brain and spinal cord. There are different types of glial cells.

Booklets and resources

Astrocytoma

Astrocytoma is the most common type of glioma. It develops from a star-shaped glial cell called an astrocyte. Astrocytomas can be low- or high-grade.

Oligodendroglioma

An oligodendroglioma is made up of cells that look similar to glial cells, called oligodendrocytes. These cells wrap around nerve cells and act as a layer of insulation. This helps our nerves send messages when telling our body to do something.

There are two main grades of these tumours – grade 2 and grade 3.

Ependymoma

An ependymoma (pronounced e-pen-da-moma) is a rare type of glioma. It is made up of cells that look similar to glial cells, called ependymal cells. These cells line the fluid-filled spaces (ventricles) in the brain and the centre of the spinal cord. This type of tumour can develop in any part of the brain or spine.

Ependymomas can be grade 1 to 3.

Getting support

Being diagnosed with a brain tumour may cause a range of different emotions. There is no right or wrong way to feel. It may help to get support from family, friends or a support organisation.

The language we use


We want everyone affected by cancer to feel our information is written for them.


We want our information to be as clear as possible. To do this, we try to:

  • use plain English
  • explain medical words
  • use short sentences
  • use illustrations to explain text
  • structure the information clearly
  • make sure important points are clear.

We use gender-inclusive language and talk to our readers as ‘you’ so that everyone feels included. Where clinically necessary we use the terms ‘men’ and ‘women’ or ‘male’ and ‘female’. For example, we do so when talking about parts of the body or mentioning statistics or research about who is affected.
