Brain Cancer

 

The brain and spinal cord make up the central nervous system in the body, they both play important roles in controlling how your body works. The roles, or functions include thoughts, speech, physical conditions, emotions, vision, movement, hearing and sensation. Many of these functions can be affected if a brain tumour develops.

There are many types of brain tumours which may be formed by the abnormal growth of cells. These abnormal growths can develop in different parts of the brain or spinal cord.

Malignant (cancerous) brain tumours tend to grow quickly and often spread into other brain tissue. Sometimes the tumour can grow into or press onto different areas of the brain. This may cause part of the brain to stop functioning the way it should under normal conditions.

In some cases brain tumours may have started as a cancer in a different part of the body and spread to parts of the brain. This is known as metastatic cancer. These tumours are usually more common than primary brain tumours, which originate in the brain area itself.

The different types of brain tumours are named based on the specific cell in which they developed in and also where the tumour first developed.

Most primary brain tumours begin in the glial cells. This type of tumour is called a glioma.

One of the most common types of primary brain tumours is known as Glioblastoma (GBM). GBM can spread throughout the brain tissue but rarely spreads to areas outside of the nervous system.
