Cancer incidence in Montana: rates for American Indians exceed those for whites.

Objectives: Previous studies suggested that the cancer incidence rates in American Indians and Alaska Natives were lower than in other groups. The objective of this study was to compare the cancer incidence rates in American Indians and whites in Montana.

Methods: Age-adjusted 6-year cancer incidence rates were calculated for American-Indian and white men and women in Montana to allow comparison of rates in 1991-1996 to those in 1997-2002.
