The term that describes low white blood cell counts is leukopenia. Leukopenia is a condition where there is a reduced number of white blood cells (WBCs) in the blood, which can make it difficult for the body to fight infections. White blood cells are a crucial part of the immune system, and having a low count can lead to increased susceptibility to illnesses.

Neutropenia, while related, specifically refers to a decrease in neutrophils, which are a specific type of white blood cell that plays a vital role in the immune response, particularly in fighting off infections. Therefore, although neutropenia is a form of leukopenia, leukopenia encompasses all types of white blood cells, not just neutrophils.

Thrombocytopenia refers to low platelet counts, which affects blood clotting rather than immune response. Myelopathy is a term that describes a condition involving the spinal cord and is unrelated to blood cell counts. Understanding these definitions is crucial for recognizing the broader implications of low white blood cell counts in clinical settings, especially in cancer patients undergoing treatments that can affect their immune function.
