Oligodendrogliomas are a rare type of tumour that usually starts in the brain or sometimes the spinal cord.
It’s best to read this along with our general information about brain tumours and spinal cord tumours. This has more detail about tests and treatments. We also have information about brain tumours that’s written just for teens and young adults.
This information is about oligodendroglioma in adults. If you need information about oligodendroglioma in children, you can contact the Children’s Cancer and Leukaemia Group.
Oligodendrogliomas belong to a group of tumours called gliomas. Gliomas are tumours that develop from the main supporting cells (glial cells) in the brain or spinal cord. Different types of gliomas are named after the different types of glial cells. Oligodendroglioma is a glioma that develops from a type of glial cell called an oligodendrocyte. These cells make up the fatty covering of nerve cells.
Oligodendrogliomas usually start in the brain, or sometimes in the spinal cord. They can sometimes spread from where they started to other parts of the brain or spinal cord. They don’t spread to other parts of the body.
These tumours are more likely to affect people who are in their 40s and 50s.
