leukemia cell
(loo-KEE-mee-uh sel)
An abnormal type of white blood cell that builds up in the bone marrow and blood of patients with leukemia, causing there to be less room for healthy blood cells. This can cause infection, anemia, and easy bleeding. Leukemia cells may also collect in the lymph nodes, spleen, and liver and cause them to swell. They may also spread to the brain, spinal cord, and testicles.
