Hairy Cell Leukemia Fund

Hairy Cell Leukemia is a rare type of blood cancer that affects a kind of white blood cell called B cells. These cells build up in the bone marrow and spleen, making it hard for the body to make healthy blood cells. People with this condition may feel tired, get infections often, or notice a swollen spleen. It usually grows slowly and can be treated with medications like chemotherapy or targeted therapy.
