Living with Medulloblastoma

A cancerous brain tumor in the lower back part of the brain (cerebellum), mostly seen in children.

Understanding Medulloblastoma

Medulloblastoma is a cancerous, fast-invading tumor that starts in the cerebellum, the part of the brain that helps with balance and coordination.

It occurs mostly in children and can spread through the fluid pathways around the brain and spinal cord. There are four types based on how the cells look. It can happen at any time in life.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Poor balance and coordination (ataxia)
  • Headache
  • Nausea and vomiting
  • Unusual sleepiness (lethargy)
  • Raised pressure inside the skull
  • Tremor with movement

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include brain and nervous system specialists and cancer specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
