Introduction: We have previously shown that immigrants have lower attendance in BreastScreen Norway than non-immigrants and that non-Western immigrants have lower incidence of breast cancer, but more advanced disease.
Purpose: To compare breast cancer-specific survival for immigrants versus non-immigrants diagnosed with screen-detected or symptomatic breast cancer.
Material And Methods: We analyzed data from 28,320 women aged 50-69 diagnosed with breast cancer after being invited to BreastScreen Norway.
Objective: To explore attendance at organised mammographic screening among immigrant groups that received an invitation letter and information leaflet (invitation) in their language of origin and Norwegian compared with Norwegian only.
Design: Randomised controlled trial.
Setting: Population based screening programme for breast cancer in Norway (BreastScreen Norway), which invites women aged 50-69 to two-view mammographic screening biennially.
Objective: Irregular attendance in breast cancer screening has been associated with higher breast cancer mortality compared to regular attendance. Early performance measures of a screening program following regular versus irregular screening attendance have been less studied. We aimed to investigate early performance measures following regular versus irregular screening attendance.

Setting: This study was conducted on data from a population-based screening program inviting women aged 50-69 to biennial two-view mammography.
Methods: We used de-identified data from 883,020 women invited to BreastScreen Norway, 2004-2020, to analyze invitations, participation, recalls, biopsies, cancer detection, and histopathological tumor characteristics.
Aims: This study aimed to analyse results on early screening outcomes, including recall and cancer rates, and histopathological tumour characteristics among non-immigrants and immigrants invited to BreastScreen Norway.
Methods: We included information about 2, 763,230 invitations and 2,087,222 screening examinations from 805,543 women aged 50-69 years who were invited to BreastScreen Norway between 2010 and 2019. Women were stratified into three groups based on their birth country: non-immigrants, immigrants born in Western countries and immigrants born in non-Western countries.
