Statistics

According to the U.S. Cancer Statistics: 2004 Incidence and Mortality report, more than 100,000 cases of hematologic cancers were diagnosed in the United States in 2004, and 54,264 people died from these cancers that same year.¹ Hematologic cancers include leukemias, lymphomas, and myeloma.

Note: The word "significantly" below refers to statistical significance. 2004 is the latest year for which trend data are available.

Leukemia

• The incidence of leukemia in the United States increased by 0.2% per year from 1975 to 2004.²



• Deaths from leukemia decreased by 0.8% per year from 1995 to 2004. This trend is particularly notable among children, for whom deaths from acute leukemia decreased by 2.9% per year from 1990 to 2004.²

Lymphoma

• The incidence of non-Hodgkin lymphoma increased in the United States by 0.7% per year from 1991 to 2004. This increase is particularly notable among women, for whom the incidence of non-Hodgkin lymphoma increased 1.4% per year from 1988 to 2004.²



• Conversely, deaths from non-Hodgkin lymphoma decreased significantly in the United States by 3.3% per year from 1997 to 2004.²
• The incidence of Hodgkin lymphoma declined by 0.2% per year from 1975 to 2004.²



• Death rates from Hodgkin lymphoma have declined at a faster rate: 6.8% per year during the same time period.²

Myeloma

• The incidence of myeloma in the United States increased by 0.7% per year from 1975 to 2004.²



• The incidence of myeloma increased 0.6% per year among African Americans. Declines were noted from 1997 to 2004 for African American women (2.8% per year, though this was not statistically significant).²
• Deaths from myeloma in the United States decreased significantly by 3.0% per year from 2002 to 2004. During 1995 to 2004, myeloma deaths among African Americans decreased significantly by 1.4% per year.²
