More than 38% of both screen-detected and interval cancers were assigned the highest artificial intelligence risk score on screening mammograms that preceded breast cancer diagnosis.<p> <p>Background - Few studies have evaluated the role of artificial intelligence (AI) in prior screening mammography.<p> <p>Purpose - To examine AI risk scores assigned to screening mammography in women who were ...

Objectives To compare results of selected performance measures in mammographic screening for an artifcial intelligence (AI) system versus independent double reading by radiologists.<p> <p>Methods In this retrospective study, we analyzed data from 949 screen-detected breast cancers, 305 interval cancers, and 13,646 negative examinations performed in BreastScreen Norway during the period from 2010 ...

Purpose - To investigate radiologists’ interpretation scores of screening mammograms prior to diagnosis of screen-detected and interval breast cancers retrospectively classified as missed or true negative.<p> <p>Methods - We included data on radiologists’ interpretation scores at screening prior to diagnosis for 1223 screen-detected and 1007 interval cancer cases classified as missed or true ...

Several studies have shown that attendance rates are lower among non-Western immigrants than among natives. As the Nordic countries have quite similar health systems and populations but also differences in the organisation of their organised mammography screening programmes, differences in attendance rates could highlight organisational factors that might increase the attendance rates. Mammography ...

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. Methods We used information ...

Purpose: To describe and compare early screening outcomes before, during and after a randomized controlled trial with digital breast tomosynthesis (DBT) including synthetic 2D mammography versus standard digital mammography (DM) (To-Be 1) and a follow-up cohort study using DBT (To-Be 2). <p><p>Methods: Retrospective results of 125,020 screening examinations from four consecutive screening rounds ...

Introduction - Experience of pain during screening mammography is shown to affect further attendance negatively. We aimed to explore the experience of pain during screening mammography using three different breast compression paddles.<p> <p>Methods - Using a self-report questionnaire, we collected information on pain experienced during mammography from 938 women screened in Bodø at Nordland ...

Background - Comparing the impact of the COVID-19 pandemic on the incidence of newly diagnosed breast tumors and their tumor stage between the Netherlands and Norway will help us understand the effect of differences in governmental and social reactions towards the pandemic.<p< <p>Methods - Women newly diagnosed with breast cancer in 2017–2021 were selected from the Netherlands Cancer Registry and ...

Mammografiprogrammet (engelsk: BreastScreen Norway) er det offentlige screeningprogrammet for brystkreft i Norge. Det startet som et pilotprosjekt i 1995 og ble gradvis landsdekkende frem til 2005. Programmet inviterer alle kvinner i alderen 50-69 år til mammografiscreening hvert annet år. Kreftregisteret har det administrative ansvaret for Mammografiprogrammet, mens screening skjer ved 30 ...

Objectives We explored associations between mammographic features and risk of breast cancer death among women with small (<15 mm) and large (≥15 mm) invasive screen-detected breast cancer.<p> <p>Methods We included data from 17,614 women diagnosed with invasive breast cancer as a result of participation in BreastScreen Norway, 1996–2020. Data on mammographic features (mass, spiculated mass, ...
