Living with Acute monocytic leukemia

A common subtype of acute myeloid leukemia, mostly described in children, with tiredness, pale skin, and fever.

Understanding Acute monocytic leukemia

Acute monocytic leukemia (AML-M5) is one of the most common subtypes of acute myeloid leukemia (AML).

It is defined by a high share of immature cells called monoblasts in the bone marrow. It can cause a very high white blood cell count, clotting problems, nervous system problems, and leukemia cells in the skin or gums. GARD lists the onset as childhood.

Signs & symptoms

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

  • Tiredness (fatigue)
  • Low red blood cells (anemia)
  • High white blood cell count
  • Shortness of breath with activity
  • Pale skin
  • Dizziness

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 blood and bone marrow specialists and cancer specialists.

  3. Ask which tests can help

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