Hairy Cell Leukemia
Hairy cell leukemia is the most uncommon type of leukemia. Many people view it as a subset of Chronic Lymphocytic Leukemia. According to Mayo Clinic, approximately 600 to 800 new cases are diagnosed each year. Middle-aged men are the most likely to be diagnosed with it, and it is rarely if ever seen in children.

Hairy cell leukemia is a slow-growing disease in which the bone marrow makes too many “B” cells, a type of white blood cell that fights infection. Hairy cell leukemia gets its name from the fine projections on these cells that, under a microscope, look like hair.
