Key Statistics About Waldenstrom Macroglobulinemia

On this page

Waldenstrom macroglobulinemia (WM) is rare, with an incidence rate of about 3 cases per million people per year in the United States. About 1,000 to 1,500 people are diagnosed with WM each year in the United States.

WM is more common in men than it is in women , and it is much more common among White people than Black people.

There are few cases of WM in younger people, but the chance of developing this disease goes up as people get older. The average age of people when they are diagnosed with WM is 70 .

Statistics on survival are discussed in Survival Rates for Waldenstrom Macroglobulinemia.
