Stages

ON THIS PAGE: You will learn about how doctors usually describe a cancer’s growth or spread, called the stage, and how this differs for Waldenström’s macroglobulinemia. To see other pages in this guide, use the colored boxes on the right side of your screen, or click “Next” at the bottom.

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 determine 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 (chance of recovery). There are different stage descriptions for different types of cancer.

There is no standard system for staging Waldenström’s macroglobulinemia. Instead, doctors may look at several factors to determine a prognosis, such as the severity of a patient’s anemia (low level of red blood cells), the amount of IgM in the blood, and the amount of a protein in the blood called beta-2-microglobulin. People with normal hemoglobin (the protein that carries oxygen in a red blood cell) levels and low beta-2-microglobulin levels typically have a better prognosis.

Information about your prognosis will help the doctor recommend a treatment plan for you. Choose “Next” (below, right) to continue reading about treatment options for this type of cancer. Or, use the colored boxes located on the right side of your screen to visit any section.
