Hairy cell leukemia (HCL) is a rare blood cancer and slow-growing due to spinal cord cells produce too many B cells (lymphocytes), a type of white blood cells that fight infection in charge. When viewed with a microscope, it looks abnormal B cells and 'hair'.
As the number of leukemia cells, automated white blood cells, red blood cells and platelets are also getting a little healthier because of being pressured by the leukemia cells.
This cancer is more common in men, particularly middle-aged or elderly men.
Until now, the cause and cure of this disease has never been found. Hairy cell leukemia is considered as one of the chronic diseases because the disease is never completely lost though maybe in a few years the treatment dose is reduced.
