- White blood cells (WBC), also called lymphocytes, are most often involved in leukemia. Their main job is to help the immune system.
- Red blood cells (RBC) carry oxygen throughout the body.
- Platelets help the blood clot at injury sites.
- Acute lymphocytic leukemia (ALL)
- Acute myelogenous leukemia (AML)
- Chronic lymphocytic leukemia (CLL)
- Chronic myelogenous leukemia (CML)
|White Blood Cells|
|Leukemia cells outnumber healthy white blood cells and gather in spleen and lymph nodes.|

Age—leukemia is most common in people over aged 60
- AML and CLL are most common in adults
- ALL is most common in children
- Chemotherapy for previous cancer
- Some genetic diseases such as Down syndrome
- Chronic exposure to benzene that exceeds federally approved safety limits
- Radiation therapy from previous therapy
- Myelodysplastic syndrome—a blood disease; increases risk for AML
- Exposure to tobacco smoke
- Fever or night sweats
- Flu-like symptoms
- Minor cuts that heal slowly
- Excessive reaction to insect bites
- Feeling weak or tired
- Pale skin
- Bleeding and bruising easily
- Bleeding gums
- Tiny red spots under the skin
- Pain in the bones or joints
- Puffy gums
- Difficulty breathing
- Swelling of testicles
- Swelling or discomfort in the abdomen (from enlarged spleen)
- Swollen lymph nodes (particularly in neck or armpit)
- Weight loss
- Meningitis with headache, nausea, loss of muscle control, seizures, symptoms of stroke
- Blood tests—to look for leukemia cells in blood
- Bone marrow aspiration and biopsy—the removal of a sample of bone marrow to look for cancer cells
- Lumbar puncture—removal of liquid that surrounds the brain and spinal cord
- Chest x-rays—to look for signs of cancer in the chest
- CT scan—type of x-ray that uses a computer to make pictures of structures inside the body
- MRI scan—test that uses magnetic waves to make pictures of structures inside the body
- Ultrasound—test that uses sound waves to examine masses and organs inside the body
- Positron emission tomography (PET)—test makes images that show the amount of activity in body tissues
- Imatinib mesylate (Gleevec)—used to treat myeloid leukemia by reducing the number of cancer cells in the blood and bone marrow
- Nilotinib—targeted therapy similar to imatinib
- Dasatinib—targeted therapy similar to imatinib (if leukemia cells become resistant to imatinib)
- Filgrastim (Neupogen)
- Pegfilgrastim (Neulasta)
- Epoetin alpha (Procrit, Epogen)
- Blood transfusions—Healthy blood cells from a donor are given through an intravenous line (IV). This may be done if the leukemia is causing shortness of breath, fatigue, or severe bleeding.
- Bone marrow transplant—Stem cells from a donor’s healthy bone marrow are injected in you. Stem cells can make all types of blood cells. Once injected into your bloodstream, the stem cells should make healthy blood cells.
- Splenectomy—The spleen may need to be removed if it becomes congested with leukemia cells.
Biological Therapy (Immunotherapy)
- Avoid exposure to benzene.
- Avoid exposure to high levels of radiation when possible.
- If you smoke, quit.
