Brain Tumours
Incidence
Approx 3500 cases per year in England and Wales.
Age
Rare below 30 years - but relatively evenly distributed thereafter (peak at age 60-69 years).
Patients with brain tumours typically present with one of the following:
- Progressive weakness, numbness, difficulty speaking/slurring, tremor and incoordination) developing over days to weeks
- Fitting/seizures
- Symptoms of raised intracranial pressure ie ( headache, vomiting, visual disturbance)
- Personality (mental state) changes
Prevalence among patients presenting with brain tumours:
- Specific weakness/numbness: > 50%
- Seizures: 25-30%
- Headaches: 25-35%
- Visual change: 23-50%
- Mental changes: 16-20%
The probability of having a brain tumour in the following situations is as follows:
- New onset fits/seizures disorder in adults: 2-6%
- New onset epilepsy: 10%
- Headache of non-migrainous type: <1%
See your doctor if you have:
- Progressive neurological problem developing over days to weeks (e.g. weakness, sensory loss, difficulty speaking/slurring, tremor and incordination )
- New onset seizures characterised by one or more of the following:
- Affecting one part of body
- Prolonged post-fit focal weakness (longer than one hour)
- Prolonged fitting (status epilepticus)
- Patients with headache, vomiting and visual disturbance
- Cranial nerve palsy (e.g. double vision, visual failure including optician defined visual field loss, one sided progressive hearing loss)
- Non-migrainous headaches of recent onset, present for at least one month, when accompanied by features suggestive of raised intracranial pressure (e.g. woken by headache; vomiting; drowsiness)
