Leukemia is named after the leukocytes, white blood cells which mutate before maturity and become cancerous. These cells reproduce rapidly, suppressing production of normal white cells that are essential to fighting infection in the body, and red cells that are needed to carry oxygen in the blood. Cancer cells may spread to the liver, spleen, lymph nodes, genitals, or the brain.

Acute Leukemias

Acute leukemia is rapidly progressive if not treated and involves more immature cells. It develops rapidly from the earliest forms of cells in the immature bone marrow cells (blasts). It requires urgent medical treatment but is generally responsive to chemotherapy.


  • Chromosomal defects
  • Radiation exposure
  • Some chemotherapy drugs
  • Toxins (benzene)
  • Persons with Down syndrome having brother or sister with leukemia are at increased risk
