Health disparities are differences in the incidence, prevalence, and mortality of a disease and the related adverse health conditions that exist among specific population groups. These groups may be characterized by gender, age, ethnicity, education, income, social class, disability, geographic location, or sexual orientation.¹

According to CDC's Office of Minority Health and Health Disparities, life expectancy and overall health have improved in recent years for most Americans. Despite this, not all Americans are benefiting equally. CDC monitors trends and patterns in cancer incidence and mortality and identifies which populations are disproportionately affected by the disease.

United States Cancer Statistics: 2004 Incidence and Mortality² reports the following trends by race/ethnicity for all cancers combined (rates are per 100,000 persons and are age-adjusted to the 2000 U.S. standard population).

For men, for all cancers combined:

• Incidence rates are highest among black (607.3), followed by white (527.2), Hispanic* (415.5), Asian/Pacific Islander (325.8), and American Indian/Alaska Native (288.6) men.



• Death rates are highest among black (303.5), followed by white (224.8), Hispanic* (152.8), American Indian/Alaska Native (151.2), and Asian/Pacific Islander (137.0) men.

For women, for all cancers combined:

• Incidence rates are highest among white (405.9), followed by black (379.7), Hispanic* (318.6), Asian/Pacific Islander (267.4), and American Indian/Alaska Native (242.2) women.



• Death rates are highest among black (182.8), followed by white (156.4), American Indian/Alaska Native (110.7), Hispanic* (101.9), and Asian/Pacific Islander (92.3) women.

*Hispanics may be of any race.

In addition to differences between racial and ethnic groups, important disparities also exist within these groups by geography, national origin, economic status, and other factors. For example, the Annual Report to the Nation on the Status of Cancer, 1975–2004, Featuring Cancer in American Indians and Alaska Natives³ reports the following trends:

• Overall, cancer incidence rates for American Indian/Alaska Native persons were lower than for whites, but they were higher for cancers of the stomach, liver, cervix, kidney, and gallbladder.



• Cancer incidence rates among American Indian/Alaska Native persons vary a great deal from one region to another, and are highest in Alaska and the Northern and Southern Plains, and lowest in the Southwest.



• For cancers of the breast and cervix, American Indian/Alaska Native women are less likely than white women to have their cancer found early.
