An oligodendroglioma is a rare type of brain tumour originating from oligodendrocytes, the cells in your brain responsible for producing myelin, which helps nerve cells communicate. This tumour can affect adults and varies in how fast it grows, and it’s potential to spread. Symptoms might include seizures, headaches, or changes in behaviour or personality, depending on the tumour’s location. Treatment often involves surgery to remove as much of the tumour as possible, possibly followed by radiation or chemotherapy to target any remaining cells. Your medical team will work closely with you to determine the best approach based on your specific condition.
