Alaska Native cancer update: incidence rates 1989-1993

Five-year average annual age-adjusted cancer incidence rates for Alaska Natives (Eskimos, Indians, and Aleuts) for the most recent period (1989-1993) are compared to rates of 20 years earlier. Rates for all cancers combined increased 28 and 25% in men and women, respectively, during the 25-year interval. Increases were seen in men in cancers of the lung, prostate, and colon and in women for cancers of the lung, breast, and corpus uteri. Rates are also compared to data from the the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) program for United States whites. Rates for all cancers combined in Alaska Native women are now similar to those of United States whites, whereas rates in Alaska Native men are lower than the United States, but only 10% lower. Significant site-specific differences previously reported between Alaska Natives and United States whites persist.
