Living with Pituitary carcinoma

A rare cancer of the pituitary gland at the base of the brain, often making extra hormones such as prolactin or ACTH.

Understanding Pituitary carcinoma

Pituitary carcinoma is a rare cancer that starts in the front part of the pituitary gland, or in a pituitary growth (adenoma) that was already there.

Most of these tumors make hormones, usually prolactin or ACTH. Related conditions include too much prolactin, Cushing disease and acromegaly. Doctors diagnose it when the cancer has spread (metastases). It can appear at any time in life.

Signs & symptoms

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

  • Headache
  • Blurry or reduced vision
  • Loss of parts of the visual field
  • Enlarged pituitary gland
  • Too much prolactin or ACTH in the blood
  • Low pituitary hormone levels (hypopituitarism)

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 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
