Living with Childhood acute lymphoblastic leukemia

A cancer of the blood and bone marrow in children, where immature white blood cells grow in large numbers and do not work well.

Understanding Childhood acute lymphoblastic leukemia

Childhood acute lymphoblastic leukemia (ALL) is a cancer of the blood and bone marrow, and the most common type of cancer in children.

In children with this condition, the bone marrow makes too many immature white blood cells (lymphoblasts, B lymphocytes, or T lymphocytes). These cells do not work normally and have trouble fighting infections.

Signs & symptoms

Symptoms vary from child to child. GARD says they may include:

  • Fever
  • Easy bruising or bleeding
  • Bone or joint pain
  • Painless lumps in the neck, underarm, stomach, or groin
  • Weakness and tiredness (fatigue)
  • Loss of appetite

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

    Your doctor may refer you to a specialist who knows rare conditions.

  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.
