Living with Pilocytic astrocytoma

A slow-growing, often noncancerous tumor of the brain or spinal cord, most common in children and young adults.

Understanding Pilocytic astrocytoma

Pilocytic astrocytoma is an often benign (noncancerous), slow-growing tumor of the brain or spinal cord.

The tumor may form a cyst and usually does not spread to nearby tissue. It most commonly occurs in children and young adults. It is also seen in people with neurofibromatosis type 1 (NF1), Li-Fraumeni syndrome and tuberous sclerosis. Symptoms depend on the size and location of the tumor.

Signs & symptoms

Symptoms vary depending on the size and location of the tumor. Most come from pressure on the brain:

  • Headaches
  • Nausea
  • Vomiting
  • Balance problems
  • Vision changes

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.
