ABI+

Benign brain tumour

Date: May 2011

Definition:

A non-malignant tumour or cyst in the brain, cranial nerves or meninges within the skull, resulting in permanent neurological deficit with persisting clinical symptoms.

For the above definition, the following are not covered:

  • tumours in the pituitary gland;
  • angiomas.

In addition, the requirement for permanent neurological deficit with persisting clinical symptoms will be waived if the benign brain tumour is surgically removed.

No change since April 2007

 

What does this mean?

Unlike cancer, which is a malignant tumour, benign tumours are localised and grow by expansion only. They therefore do not invade and destroy surrounding tissue and do not spread to other parts of the body. Once surgically removed they tend not to recur.

However, a benign tumour can still be very dangerous because it can put pressure on the brain and lead to possible damage, haemorrhage and ulceration. Deficit to the neurological system means muscle weakness or sensory loss. Surgery to cure the condition may not always be possible.
