Diagnostic tests
The following are the examination procedures commonly required for the diagnosis
and pre-treatment evaluation:
1. Blood test - Blood counts, liver function test, renal function test.
2. X-ray, ultrasound, computerized tomography (CT) scan or magnetic resonance
imaging (MRI) - these methods of investigation will help to identify the site
of the primary tumour and also the extent of the disease.
3. Tissue examination such as bone marrow examination, lymph node biopsy or
excision of mass - to confirm the cancer type.
4. Lumbar puncture - some types of childhood cancer may spread to the brain
and central nervous system. An examination of the cerebrospinal fluid by lumbar
puncture (spinal tap) may help such diagnosis.
Based on these findings, the doctor will determine the appropriate treatment
for the patient. During treatment, some tests or examination will be repeated
in order to monitor the response to treatment.
