Breast cancer mortality in participants of the Norwegian Breast Cancer Screening Program
(Cancer;119(17), Journal article; Peer reviewed, 2013-05-29)BACKGROUND The Norwegian Breast Cancer Screening Program started in 1996. To the authors' knowledge, this is the first report using individual-based data on invitation and participation to analyze breast cancer mortality ... -
Breast compression across consecutive examinations among females participating in BreastScreen Norway
(British Journal of Radiology;Volume 91, Issue 1090, Journal article; Peer reviewed, 2018-07-13)Objective: Breast compression is used in mammography to improve image quality and reduce radiation dose. However, optimal values for compression force are not known, and studies have found large variation in use of compression ... -
Breast compression and experienced pain during mammography by use of three different compression paddles
(European Journal of Radiology;Volume 115, June 2019, Journal article; Peer reviewed, 2019)Objectives: We aimed to compare pain experienced during screening mammography, using three different compression paddles: a fixed paddle standardizing pressure (study paddle), a flexible, and a fixed paddle. Material and ... -
Compression forces used in the Norwegian Breast Cancer Screening Program
(Journal article; Peer reviewed, 2017)Objective: Compression is used in mammography to reduce breast thickness, which is claimed to improve image quality and reduce radiation dose. In the Norwegian Breast Cancer Screening Program (NBCSP), the recommended ... -
Cost differences between digital tomosynthesis and standard digital mammography in a breast cancer screening programme: results from the To-Be trial in Norway
(European Journal of Health Economics;Volume 20, pages 1261–1269 (2019), Journal article; Peer reviewed, 2019-07-31)Background: Several studies in Europe and the US have shown promising results favouring digital breast tomosynthesis compared to standard digital mammography (DM). However, the costs of implementing the technology in ... -
Gender, letters, relatives, and God: mediating actors in mammographic screening among Pakistani women in Norway.
(Acta Radiologica Open;Volume 8, issue 9, Journal article; Peer reviewed, 2019-08-19)Background: Pakistani immigrant women in Norway have lower attendance rates in the national breast cancer screening program (BreastScreen Norway) compared to non-immigrants and immigrants from most other countries. Purpose: ... -
Lower attendance rates in immigrant versus non-immigrant women in the Norwegian Breast Cancer Screening Programme
(Journal article; Peer reviewed, 2017)Objective The Norwegian Breast Cancer Screening Programme invites women aged 50-69 to biennial mammographic screening. Although 84% of invited women have attended at least once, attendance rates vary across the country. ... -
Patterns of aggressiveness: Risk of progression to invasive breast cancer by mammographic features of calcifications in screen-detected ductal carcinoma in situ
(Peer reviewed; Journal article, 2021)Background Mammographic features of calcifications on mammograms showing invasive breast cancer are associated with survival. Less is known about mammographic features and progression to invasive breast cancer among women ... -
Polymorphisms in hormone metabolism and growth factor genes and mammographic density in Norwegian postmenopausal hormone therapy users and non-users
(Breast Cancer Research;14 (R135), Journal article; Peer reviewed, 2012-10-27)Introduction Mammographic density (MD) is one of the strongest known breast cancer risk factors. Estrogen and progestin therapy (EPT) has been associated with increases in MD. Dense breast tissue is characterized by ... -
Radiological review of prior screening mammograms of screen-detected breast cancer
(European Radiology;, Journal article; Peer reviewed, 2020-10-01)Objective: To perform a radiological review of mammograms from prior screening and diagnosis of screen-detected breast cancer in BreastScreen Norway, a population-based screening program. Methods: We performed a ... -
A randomized controlled trial of digital breast tomosynthesis versus digital mammography in population-based screening in Bergen: interim analysis of performance indicators from the To-Be trial
(European Radiology;March 2019, Volume 29, Issue 3, Journal article; Peer reviewed, 2018-08-29)Objectives: To describe a randomized controlled trial (RCT) of digital breast tomosynthesis including synthesized two dimensional mammograms (DBT) versus digital mammography (DM) in a population-based screening program for ... -
The readout thickness versus the measured thickness for a range of screen film mammography and full-field digital mammography units
(Medical physics (Lancaster);39 (1), Journal article; Peer reviewed, 2011-12-20)Purpose: To establish a simple method to determine breast readout accuracy on mammography units. Methods: A thickness measuring device (TMD) was used in conjunction with a breast phantom. This phantom had compression ... -
Risk of breast cancer after false-positive results in mammographic screening
(Journal article; Peer reviewed, 2016)Women with false-positive results are commonly referred back to routine screening. Questions remain regarding their long-term outcome of breast cancer. We assessed the risk of screen-detected breast cancer in women with ... -
Screening at stationary versus mobile units in BreastScreen Norway
(Journal of Medical Screening;Vol 27, Issue 1, 2020, Journal article; Peer reviewed, 2019-08-20)Objective To compare breast characteristics, compression parameters, and early performance measures (rates of recall, screen-detected and interval breast cancer, and histopathologic tumour characteristics) for mammographic ... -
Survival among women diagnosed with screen-detected or interval breast cancer classified as true, minimal signs, or missed through an informed radiological review
(European Radiology;, Journal article; Peer reviewed, 2020-11-12)Objectives: “True” breast cancers, defined as not being visible on prior screening mammograms, are expected to be more aggressive than “missed” cancers, which are visible in retrospect. However, the evidence to support ... -
True and Missed Interval Cancer in Organized Mammographic Screening: A Retrospective Review Study of Diagnostic and Prior Screening Mammograms
(Academic Radiology;Volume 29, Supplement 1, January 2022, Pages S180-S191, Peer reviewed; Journal article, 2021-04-21)Rationale and Objectives: To explore radiological aspects of interval breast cancer in a population based screening program.
