Breast cancer is a leading cause of cancer morbidity and mortality among American Indian and Alaska Native (AI/AN) women.Although published studies have suggested that breast cancer rates among AI/AN women are lower than those among other racial and ethnic populations, accurate determinations of the breast cancer burden have been hampered by misclassification of AI/AN race. Cancer incidence data from the National Program of Cancer Registries and the Surveillance, Epidemiology, and End Results Program were combined to estimate age-adjusted rates for the diagnosis years 1999 through 2004.In Canada and Greenland, Inuit circulated almost exclusively north of the "Arctic tree line", the effective southern border of Inuit society.Methamphetamine has been identified as one of the largest threats to public safety in Indian Country.The rate in Alaska was similar to the rate among non-Hispanic white (NHW) women in Alaska.Overall, AI/AN women had lower rates of breast cancer than NHW women, but AI/AN women were more likely to be diagnosed with late-stage disease. To the authors’ knowledge, this report provides the most comprehensive breast cancer incidence data for AI/AN women to date.
The Greenlandic Inuit are descendants of indigenous migrations from Canada.
The wide regional variation indicates an important need for etiologic and health services research, and the large percentage of AI/AN women with late-stage disease demands innovative approaches for increasing access to screening.
In the United States and Canada, the term "Eskimo" was commonly used to describe the Inuit and Alaska's Yupik and Iñupiat peoples.
They are citizens of Denmark, although not of the European Union. They had split from the related Aleut group about 4,000 years ago and from northeastern Siberian migrants, possibly related to the Chukchi language group, still earlier. They were thought to have become completely extinct as a people by about 1400 or 1500. Collins determined that, based on the ruins found at Native Point, the Sadlermiut were likely the last remnants of the Dorset culture, or Tuniit.
In contrast to other Tuniit populations, the Aleut and Sadlermiut benefited from both geographical isolation and their ability to adopt certain Thule technologies.
