ON THIS PAGE: You will learn about how doctors describe a cancer’s growth or spread. This is called the stage. To see other pages in this guide, use the menu.
Staging is a way of describing where the cancer is located, if or where it has spread, and whether it is affecting other parts of the body. Doctors use diagnostic tests to find out the cancer's stage, so staging may not be complete until all 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, which is the chance of recovery. There are different stage descriptions for different types of cancer.
There is no standard system for staging Waldenstrom’s macroglobulinemia. Instead, doctors may look at several factors to determine a prognosis, such as
the severity of a patient’s anemia
a low level of red blood cells
the amount of IgM in the blood
the amount of a protein in the blood called beta-2-microglobulin
People with low beta-2-microglobulin levels and normal hemoglobin—the protein that carries oxygen in a red blood cell—typically have a better prognosis.
Information about the cancer’s factors will help the doctor recommend a specific treatment plan. The next section in this guide is Treatment Options. Or, use the menu to choose another section to continue reading this guide.
