What is a brain tumour?
A brain tumour is an abnormal growth of cells in or around the brain. Some are non-cancerous (benign) and slow-growing; others are cancerous (malignant). Symptoms depend on the tumour’s size and location.
Symptoms to discuss with a doctor
- New, persistent or worsening headaches
- Seizures, especially for the first time in an adult
- Weakness, numbness or changes in vision or speech
- Persistent nausea, balance problems or memory changes
How it is diagnosed
A detailed neurological examination is followed by imaging — usually an MRI or CT scan — to locate and characterise the tumour. Sometimes a biopsy is needed to identify the exact type.
Treatment options
Treatment depends on the tumour type and position. Surgery aims to remove as much as safely possible, often using advanced navigation for precision.
Radiotherapy and chemotherapy may follow for certain tumours. A team of neurosurgeons, oncologists and rehabilitation specialists plans care together for the best outcome.
