Leukemia - B-cell Prolymphocytic Leukemia and Hairy Cell Leukemia

Staging is a way of describing where the cancer is located, if or where it has spread, and whether it is affecting the functions of other organs in the body. Doctors use diagnostic tests to determine the cancer's stage, so staging may not be complete until all of the tests are finished. Knowing the stage helps the doctor to decide what kind of treatment is best and can help predict a patient's prognosis. There are different stage descriptions for different types of cancer.

Unlike most solid tumors, HCL and PLL do not have a formal staging system.  Talk with your doctor for details on how your specific disease will be evaluated.
