Basic Information About Health Disparities in Cancer

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, race or ethnicity, education, income, social class, disability, geographic location, or sexual orientation.1

According to CDC’s Office of Minority Health and Health Equity, life expectancy and overall health have improved in recent years for most Americans, but not all Americans are benefiting equally. CDC monitors trends in new cancer cases and cancer deaths to identify groups that are more affected by the disease.

American Indians and Alaska Natives face unique health disparities. The Annual Report to the Nation on the Status of Cancer, 1975–2004, Featuring Cancer in American Indians and Alaska Natives2 found the following trends—

  • Overall, cancer incidence rates for American Indian/Alaska Native people 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 people 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.
