Abstract
A preliminary study based on officially recorded cases of cervical carcinoma, dysplasia and carcinoma in situ in Greenlandic women in 1955-75 revealed 117 cases of carcinoma and 119 cases of dysplasia and carcinoma in situ. The incidence of invasive carcinoma, age-adjusted to European standard population (Doll 1976), exhibited a rise from 20.9/100,000 in 1955-59 to 84.8 in 1970-75. The latter incidence rate is 1 of the highest in the world, and about 2.5 times as high as the most recently recorded incidence in Denmark. Age-specific incidence rates for cervical carcinoma in Greenland for 1970-75 showed significantly higher values in the age groups 15-49 and 60-64 yr as compared with the most recent Danish rates. The crude incidence of dysplasia and carcinoma in situ per 100,000 women over 15 yr of age rose from 10.5 for 1955-59 to 137.5 for 1970-75. The corresponding incidence for severe dysplasia and carcinoma in situ was 93.7 for 1970-75. There probably was a more complete registration of these initial stages during recent years, although organized detection work was not initiated.
