Introduction[edit | edit source]
Brain tumours refers to a diverse group of neoplasms originating from intracranial tissues and the meninges with malignancy levels ranging from benign to aggressive.
Each tumour type has its own biology, treatment, and prognosis and risk factors.[1]
More than 50 per cent are malignant with poor prognosis despite surgery, radiotherapy, and chemotherapy [2]. Even benign or low -grade brain tumors can cause significant disabiity[3].
Epidemiology[edit | edit source]
Brain tumours increase in frequency with age, with a few notable exceptions and some uncommon tumours found in infancy.
Sex differences:
- Gliomas are more frequent in men
- Meningiomas are more frequent in women.[4]
Apart from genetic tendency, the largest environmental risk factor for brain tumours is exposure to high doses of ionising radiation.[1]
Classification of brain tumor[edit | edit source]
Brain tumour is an umbrella term for numerous individual tumours. Note figures shown vary significantly dependant on study. They are mainly classified into:
Gliomas, tumours that start in the glial (neuroglia) cells of the brain, most common (50%). They include: astrocytoma, most common tumours arising from glial cells (44%); ependymoma (3%); medulloblastoma (3%); oligodendroglioma (2%)
Non-glioma tumours, include:
- Meningioma, most common tumour of the meninges. (15%)
- Metastases (15%)
- Pituitary tumours (8%)
- Vestibular schwannoma (8%)
- Primary CNS lymphoma (2.5%)
- Pineal tumours
- Intracranial germ cell tumours 0.4% to 3.4%
Treatment[edit | edit source]
During and after treatment you will see a range of health professionals, which may include a medical oncologist, neuropathologist, rehabilitation specialist and exercise physiologist, who specialise in different aspects of your care.
