These tests will include a physical examination, and brain scans such as magnetic resonance imaging (MRI) or computerized tomography, which will identify the presence of a tumour. A sample of tissue will be taken at the time of surgery to confirm the diagnosis. This small piece of tumour will be removed and sent to a doctor called a pathologist. They will look at the tumour under a microscope to learn the exact type of tumour.</p> <figure class="swf-asset-c-80"> <span class="asset-image-title">Medulloblastoma MRI</span><div class="asset-animation"> src="https://akhpub.aboutkidshealth.ca/Style%20Library/akh/swfanimations/swf.html?swffile=MRI_medulloblastoma_MED_ANI_EN.swf" </div> </figure> <p>The doctors may ask permission to study the sample tumour cells further to learn more about their biology. At the moment, the results of these tests do not influence treatment.</p><h2>What is staging?</h2><p>Staging determines the type of treatment that is most appropriate, which depends on the child’s age and factors related to the tumour. Medulloblastoma is currently staged, or divided into two groups, called “average risk“ or “high risk.“</p><p>These stages are based on the collected results of previous treatments of children at hospitals around the world.</p><p>A medulloblastoma is called average risk if all of the following are true:<br></p> <figure> <span class="asset-image-title">Metastasized Tumour Cells</span> <img src="https://assets.aboutkidshealth.ca/AKHAssets/Spine_metastasis_MEDIMG_PHO_EN.jpg" alt="" /> <figcaption class="asset-image-caption">Cancer cells from a brain tumour can sometimes spread to another part of the body, such as the spinal cord.
