Having a tumour of any kind can be scary and it is the unknown that makes these feelings worse. Getting answers to questions can be reassuring and that is why we have created this section that speaks to the most common questions we hear when asked about brain tumours.

Brain Tumour Basics:

What is a brain tumour?

A brain tumour is a mass of abnormal cells within or around the structure of the brain.

What are primary brain tumours?

These tumours originate from cells within the brain and these types of tumours stay within the brain or spinal cord.

What are secondary brain tumours (or metastatic)?

These tumours originate from cells from somewhere else in the body and have moved (i.e. from a breast, lung, melanoma, etc.).

What is a benign tumour?

This type of tumour is considered a grade 1 or 2 tumour in size and is slow growing, has well defined borders and does not invade surrounding tissue.

What is a Malignant Tumour?

This type of tumour is considered a grade 3 or 4 tumour in size and is fast growing, has poorly defined borders and can invade surrounding tissue and structures.

What are the common symptoms of a brain tumour?

Headaches, seizures, visual changes, personality changes, one-sided weakness, hearing loss, dizziness, nausea and vomiting, and one-sided paralysis.

What are the types of treatments for a brain tumour?

The three standard treatments for brain tumours are surgery, radiation therapy and chemotherapy. However a wait and see approach is often used to monitor any changes in the tumour. Treatment plans are individualized to the patient and the type and grade of tumour.

Clinical Trials:

What is a clinical trial?

Clinical trials are research studies that test new ways to prevent, detect, treat or manage brain tumors. They provide valuable information about safety and effectiveness of new approaches.

Who can participate in a clinical trial?

Participation in a clinical trial may be an option, please speak to your health care team to learn about the options available. Please contact Takyee Tung by email at [email protected] to learn more.

Why do we have clinical trials?

Most standard of care practices started from clinical trials which have shown to be effective. Clinical trials help us learn more about the different types of disease and can lead to:

  • New and more effective drugs for specific types of cancer
  • Drugs with fewer side effects
  • Less invasive methods of surgery
How long do clinical trials last?

This depends on the type of clinical trials that are available and the tumour type and candidate eligibility.

Brain Tumour Bank:

What kind of samples are available in the tumor bank?

The major categories include:

  • Diffuse glioma
  • Ependymoma
  • Meningioma
  • Metastatic tumor
  • Pituitary adenoma
  • Nerve Sheath tumor
  • Lymphoma
