Cancer of the female genital tract in Circumpolar Inuit.

Cervical cancer incidence among Inuit is high. Especially women from Greenland exhibit rates which are among the highest in the world. Compared with women in Denmark, USA and Canada, Inuit women have a 3-4 time higher cervical cancer risk. By contrast, the incidence of uterine corpus cancer is low in the Circumpolar area. Both in Greenlandic and Canadian Inuit women, ovarian cancer rates are similar to those in Danish women and non-Inuit women from Canada respectively. Only 9 cases of placenta cancer were recorded in the Circumpolar area during the 20 years of observation. Compared with available incidence rates for Denmark the incidence in Greenland was significantly higher.
