Living with Glioblastoma

A cancerous brain tumor that grows from star-shaped support cells and can cause headaches, nausea, and other symptoms.

Understanding Glioblastoma

Glioblastoma is a cancerous (malignant) brain tumor that develops from brain cells called astrocytes.

Astrocytes help support and nourish nerve cells. Glioblastomas are often very aggressive and grow into nearby brain tissue. Symptoms may start when the tumor puts extra pressure on the brain, and other features depend on the size and location of the tumor. It can occur at any time in life.

Signs & symptoms

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

  • Headache
  • Nausea, vomiting, or drowsiness
  • Muscle weakness or paralysis
  • Vision loss
  • Language problems
  • Swelling of the brain

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.

  4. Connect with expert centers

    Alex's Lemonade Stand Foundation may keep lists of experts for this condition.
