Hairy Cell Leukemia (HCL)

 Hairy cell leukemia (HCL) is a cancer of white blood cells that leads to low counts of normal blood cells.

This results in:

  • anemia (as the number of erythrocytes, red blood cells being produced by the marrow decreases)
  • thrombocytopenia (deficiency in platelets, which may result in decreased ability of blood to clot)
  • neutropenia (deficiency in the phagocytic cells that attack pathogens within the body)
  • infection (as the body’s immune cell production and activity levels decrease)

bruising may occur as the blood’s ability to clot is compromised.
