A brain tumour is an abnormal growth of cells within or around the structure of the brain. They can impact all areas of the brain and change how a person thinks, feels, and reacts. There are over 120 types of brain tumours, ranging from non-malignant (non-cancerous) to malignant (harmful or cancerous). In some cases, brain tumours can put pressure on surrounding tissue, leading to long-term effects.
It is unknown what causes brain tumours. Family history, age, environmental exposure may be risk factors.
Signs and symptoms of brain tumour
Brain tumour symptoms vary from person to person and may appear overtime or all at once. Not every type of brain tumour will generate the same symptoms. The symptoms may also occur with other conditions, so may not indicate a brain tumour.
Common symptoms of a brain tumour include:
- Behavioural changes
- Cognitive changes
- Dizziness or unsteadiness
- Double or blurred vision
- Frequent headaches
- Hearing impairment
- Morning nausea and vomiting
- Seizures
- Weakness or paralysis
Symptoms of a brain tumour will depend on the size and location of the tumour, and not everyone will experience all the symptoms listed.
Diagnosis and treatment for brain tumour
A brain tumour is diagnosed by using a combination of neurological exams, magnetic resonance imaging (MRI) and computed tomography (CT) scans. Doctors will determine the best treatment for a brain tumour based on factors like:
- Age
- Overall health
- Tumour location
- Tumour size
- Tumour type
For malignant tumours (such as cancer), surgery, radiation, chemotherapy, and immunotherapy are the most recommended treatments. For more information about cancerous tumours, including metastatic cancer, visit the Brain Tumour Foundation of Canada website.
In cases where surgery is not possible or the brain tumour is not doing any harm or causing any major symptoms, doctors may recommend monitoring the tumour before making additional treatment decisions: this is called a “wait and see approach”. It’s important for the person with the brain tumour and their immediate family to discuss available treatment options with the healthcare professionals.
Brain tumour recurrence
Sometimes a brain tumour can become ‘active’ again. This could indicate growth or change in the tumour. Normally this is discovered during routine checkups. If the tumour does come back or become active again, the healthcare team will determine the best course of treatment.
