ON THIS PAGE: You will find information about the number of people who are diagnosed with MDS each year. Use the menu to see other pages.
Approximately 10,000 people in the United States are diagnosed with MDS each year. MDS is uncommon in people younger than 50. It is most common for people in their 70s. As the U.S. population continues to age, the number of people diagnosed with MDS each year is likely increasing.
Death from MDS is often caused by bleeding and/or infection from low blood cell counts or after the disease becomes acute myeloid leukemia (AML). About a third of patients with MDS develop AML.
It is important to remember that statistics on MDS are an estimate. The estimate comes from annual data based on the number of people with MDS in the United States. Talk with your doctor if you have any questions about this information. Learn more about understanding statistics.
