A brain tumour forms when cells grow and divide in an uncontrollable way. When this occurs, the tumour takes up space within the skull and can interfere with the brain's normal activity. A tumour may cause damage by increasing pressure in the brain, by shifting the brain and causing it to push against the skull, and/or by invading and damaging nerve and healthy brain tissue.
Brain tumours can be benign or malignant (brain cancer). There are two main types of brain cancer:
- Primary – a tumour that originates from the brain tissue
- Metastatic – a tumour caused by cancer elsewhere in the body that spreads to the brain
Most of these tumours have no known risk factors and occur at random. Some symptoms to be aware of are:
- Nausea and vomiting
- Weakness or numbness on one side of the body
- Changes in vision, hearing, speech or sensation
- Memory loss
- Change in mood or personality
For brain tumours, the treatment options are determined on the basis of:
- Tumour type and grade
- Location and size
- Patients age, medical history and health
Surgery, radiation therapy and chemotherapy are all used as treatment options for these tumours.
External beam Radiation therapy for Brain Tumours
External beam radiation therapy is used to treat both:
- Benign and malignant tumours, and
- Primary and metastatic brain cancer
Genesis CancerCare Queensland is equipped to provide optimal treatment for both benign and malignant brain tumours using advanced linear accelerators and modern external beam therapy techniques such as volumetric modulated arc therapy (VMAT).
Depending on the type and stage of a brain tumour, specialised stereotactic radiation therapy may be recommended. This technique can be performed using our linac based BrainLab system which is designed to provide sub-millimetre accurate treatment for small tumours that arise in highly sensitive areas of the brain.
External beam radiation therapy services for brain tumours are available at all Genesis CancerCare Queensland centres.
Specialised BrainLab stereotactic treatment is available at:
