Neutropenia is an abnormally low number of neutrophils (a type of white blood cell) in the blood. Neutropenia, if severe, significantly increases the risk of life-threatening infection. Neutropenia is often a side effect of the treatment of cancer with chemotherapy or radiation therapy.
White blood cells also grow quickly, so the treatment can attack the white blood cells as well as the cancer. Other causes of a low white blood cell count include: 1  Crohn's disease. 2  Infections, such as tuberculosis (TB) or certain viruses like HIV. 3  Lupus (also called systemic lupus erythematosus).
