Hairy cell leukemia history and symptoms

Symptoms
In hairy cell leukemia, the broken "hairy cells" build up in the bone marrow, which means that the bone marrow has difficulty producing enough normal cells: white blood cells to fight infections, red blood cells to carry oxygen, and platelets to stop bleeding. Consequently, patients usually present with infection, anemia-related fatigue, and/or easy bleeding.

Most symptoms are often vague, such as "persistent fatigue" or "not feeling well."
