What are gliomas?
Gliomas are a group of brain tumors arising from supporting cells called glia. They exist in different grades, with lower grades growing slowly and higher grades (like glioblastoma) being more aggressive and fast-growing. Common symptoms include headaches, seizures, and changes in speech, movement, or memory. Treatments involve surgery, radiation, and chemotherapy, with glioblastoma posing a significant challenge due to its aggressiveness. Research and patient-led initiatives aim to improve treatment options and potentially turn glioblastoma into a manageable condition. Early detection is crucial for optimal treatment outcomes.
Types of glioma:
- Pilocytic glioma
- Gioblastoma
- Astrocytoma
- Diffuse astrocytoma
- Anaplastic astrocytoma
- High grade astrocytoma with piloid features
- Pilocytic astrocytoma
- Gliosarcoma
- Anaplastic pleomorphic xathoastrocytoma
- Anaplastic oligodendroglioma
- Anaplastic oligoastrocytoma
- Ependymoma
How rare is it and who does it affect?
Although gliomas are the most common type of brain tumour, they are still considered to be rare cancers. There are approximately 7,800 brain tumours diagnosed in the UK each year. Glioblastomas (GBM) are even rarer, with around 450 diagnoses in the UK each year.
Gliomas can occur at any age, including in children, though they are more common in older adults. in some age groups females have slightly higher incidence; in others males do—but overall the difference is not very large.
