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.
