Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
A prospective cohort study targeting 45,000 women invited to breast cancer screening in Bergen, Hordaland in the study period, 2016-2018, will be performed. A screening participation of approximately 75% is expected. All attending women will be asked if they are willing to participate in the study after receiving written and oral information about the study. Women willing to participate in the study will sign an informed consent. Of the attending women it is expected that about 90-95% will consent to participate in the study. The women will be randomized into two groups, a study group and a control group. The randomization will take place at the screening unit in Bergen. The outcome of the randomization is based on the 11-digit personal identification number assigned to every citizen in Norway. In the study group, the women will be screened with SM+DBT. In the control group, the women will be screened with DM. Women not willing to participate in the study will be screened with DM, and not included in our study.
The investigators aim to address the following topics and research questions:
* Study 1: Early performance measures in a population based screening program using SM+DBT versus DM - interim analyses.
* Study 2: Use of SM+DBT versus DM in a population based screening program - a randomized controlled trial.
* Study 3: Prognostic and predictive histopathologic characteristics of breast tumors detected in a population based program using SM+DBT versus DM.
* Study 4: SM+DBT and DM in a populations based screening program - which technology has the highest sensitivity for women with mammographic dense breast?
* Study 5 and 6: Costs of SM+DBT and DM in a populations based screening program - is SM+DBT cost-effective?

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Digital Breast Tomosynthesis
Synthetic Mammography (SM) + Digital Breast Tomosynthesis (DBT)
The SM+DBT will be independently read by two radiologists. A consensus meeting will decide whether to recall the woman or not.
Women selected for further assessment (positive screening exam) will be recalled.
Synthetic Mammography + Digital Breast Tomosynthesis
Two-view tomosynthesis performed with GE Senoclaire 3D Breast Tomosynthesis.
Digital mammography
The digital mammograms will be independently read by two radiologists. A consensus meeting will decide whether to recall the woman or not.
Digital mammography
Two-view digital mammography performed with GE Senoclaire 3D Breast Tomosynthesis.
