Key Statistics for Chronic Myeloid Leukemia

The American Cancer Society's estimates for chronic myeloid leukemia (CML) in the United States for 2018 are:

  • About 8,430 new cases will be diagnosed with CML (4,980 in men and 3,450 in women).
  • About 1,090 people will die of CML (620 men and 470 women).

About 15% of all new cases of leukemia are chronic myeloid leukemia. About 1 person in 526 will get CML in their lifetime in the United States.

The average age at diagnosis of CML is around 64 years. Almost half of cases are diagnosed in people 65 and older. This type of leukemia mainly affects adults, and is rarely seen in children.
