Overview
A brain tumour is an abnormal growth of cells in or around the brain. It may be non-cancerous or cancerous, and its effects depend on its size and where it sits, because it can press on nearby brain areas. Symptoms build up gradually and can include new or worsening headaches, fits, or changes in vision, balance or behaviour. Many are treatable, and early assessment of persistent warning signs gives the best chance of a good outcome.
Symptoms
- New, worsening or early-morning headaches
- Seizures (fits) for the first time
- Nausea and vomiting, often in the morning
- Blurred or double vision, or blind spots
- Weakness, numbness, or changes in speech, balance or behaviour
When to see a doctor
See a doctor for a new persistent or worsening headache, a first-ever fit, or new problems with vision, balance, speech or limb strength.
Emergency — call 108 or go to the nearest hospital
- A first-ever seizure, sudden severe headache, sudden weakness or numbness, confusion, or loss of consciousness — call 108 immediately
Causes
The cause is usually unknown; a small number are linked to inherited conditions or previous radiation to the head.
