Acute Lymphoblastic Leukemia
Signs and Symptoms
Acute lymphoblastic leukemia (ALL) usually causes illness suddenly, within days or weeks. Most problems are related to the replacement of normal bone marrow and diminished normal blood counts. ALL causes bone marrow failure, which leads to:
- Low levels of red blood cells, which can cause fatigue and shortness of breath
- Low platelet counts, which can cause bleeding
- Low normal white blood cell counts, which can lead to infection
- Vulnerability to bruising, bleeding and infections
In addition to these signs of bone marrow failure, ALL sometimes can cause enlarged lymph nodes, an enlarged liver or spleen, or pain in the bones or joints.
