Brain cancer symptoms

In some cases, a brain tumour grows slowly and symptoms develop gradually, so you may not be aware that anything is wrong at first. In other cases, symptoms appear suddenly.

Many symptoms of brain tumours are more likely to be caused by other factors. However, any new, persistent or worsening symptoms should be reported to your doctor.

General symptoms – Brain tumour symptoms may be caused by increased pressure in the skull (intracranial pressure). Pressure can build up because the tumour itself is taking up too much space or because it is blocking the flow of cerebrospinal fluid around the brain.

Intracranial pressure can lead to symptoms such as:

  • headaches – often worse when you wake up
  • nausea and vomiting – often worse in the morning or after changing position (e.g. moving from sitting to standing)
  • confusion and irritability
  • blurred or double vision
  • seizures (fits) – can be obvious, involving a loss of consciousness, or more subtle, such as “zoning out”
  • weakness in parts of the body
  • drowsiness – a later symptom.

Symptoms caused by tumour position – Other symptoms relate to where in the brain or spinal cord the tumour is located – see the diagram below.
