White blood cells are a set of cells produced in the bone marrow that are part of the body’s immune system. Also called leukocytes, white blood cells can be found in blood, lymph, lymphoid organs, and various connective tissues. Several cells are part of this group called white blood cells, including:

  • Neutrophils;
  • Lymphocytes;
  • Eosinophils;
  • Basophils;
  • Macrophages;
  • Monocytes.

In general, the amount of white blood cells can be checked through the blood count. Monitoring this amount is important during cancer treatment, as chemotherapy, radiation therapy, and molecular-targeted drugs can reduce the amount of these cells in the blood, causing leukopenia. In addition, there are hematological neoplasms, such as leukemias, that can cause leukopenia.
