Staging

Staging is a way of describing a cancer, such as where it is located, if or where it has spread, and if 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, leukemias do not have a formal staging system. Serial blood counts (regular blood tests) are the main indicators used to monitor a person’s recovery from eosinophilic leukemia, as well as the elimination of any symptoms related to the disease and the percentage of immature cells in the bone marrow.
