Signs & Symptoms

Symptoms of brain cancer appear when the tumour is large enough to place pressure on the brain structures and cause alterations of its function. The symptoms will depend on the location of the tumour, and what structures are affected. Some of the possible symptoms are:

  • Frequent headaches, which typically worsen with activity.
  • Nausea and vomiting.
  • Behavioural changes such as changes in personality, thinking, and memory.
  • Difficulty speaking or understanding words.
  • Motor difficulties such as abnormal movements, difficulty walking, and imbalance.
  • Trouble swallowing and eating.
  • Vision problems such as blurred vision, double vision, and loss of vision.
  • Hearing problems.
  • Seizures.
  • Drowsiness and fatigue.
