|Childhood Cancers: Brain Tumours|
Childhood brain tumours are a diverse group of diseases
characterised by the abnormal growth of tissue contained within the skull.
Brain tumours can be benign or malignant. Other than
and , brain tumours are the
most common type of cancer that occurs in children. Brain tumours are
typically divided into Infratentorial tumours
(those that occur in the lower part of the brain) and Supratentorial
tumours (those that occur in the upper part of the brain).
If a child presents symptoms that may be caused by a brain tumour, his
or her doctor may order a computed tomographic (CT) scan, a diagnostic
test that uses computers and x-rays to create pictures of the body. A
magnetic resonance imaging (MRI) scan, a diagnostic test similar to a
CT scan but which uses magnetic waves instead of x-rays, may also be performed.
Often, a biopsy is need to confirm diagnosis.
Treatment and prognosis depend on the type of tumour, its location within
the brain, the extent to which it has spread, as well as the child's age
and general health. There is no staging for childhood brain tumours. Brain
tumours are grouped according to their location within the brain and the
appearance and behaviour of the tumour tissue. Treatment options include:
Surgery; Radiation therapy; Chemotherapy.
