What is a Brain Tumour?

What is a Brain Tumour?

  • A brain tumour is a mass of abnormal cells within or around the structure of the brain.
  • A brain tumour can be benign or malignant, and can be primary or secondary. 

 The difference between Primary and Secondary Brain Tumours:

Primary Brain Tumours   Secondary Brain Tumours (or Metastatic)

Originated from cells within the brain.

Primary brain tumours stay within the brain or spinal cord.
