White blood cells are a group of cells produced in the bone marrow and are part of the body’s immune system. Also called leukocytes, white blood cells can be found in the blood, lymph, lymphoid organs, and various connective tissues.
Several cells are part of this group called white blood cells, including:
In general, the quantity of white blood cells can be checked through a complete blood count (CBC). Monitoring this quantity, whether high or low, is important during cancer treatment, as chemotherapy, radiation therapy, and molecular target drugs can reduce the quantity of these cells in the blood, causing leukopenia. Additionally, there are hematologic neoplasms, such as leukemia, that can cause leukopenia.
