Oligodendrogliomas are primary brain tumours which means they have originated in the brain instead of spreading from elsewhere. They belong to the group of brain tumours known as gliomas as they develop from a type of glial cell known as an oligodendrocyte.
Oligodendrogliomas are the third most common glioma, accounting for 2-5% of all primary brain tumours and 5-18% of gliomas. They are more common in adults, particularly in people aged 40-60.
As with most tumours, the cause is not known. This can be a difficult thing to accept and can leave you feeling helpless, but there is nothing you could have done to prevent this from happening.
Oligodendrogliomas are divided into two grades:
The majority of oligodendrogliomas occur in the frontal lobe, and the second most common site affected is the temporal lobe.
