Objectives To estimate the impact of service mammography screening on breast cancer mortality using European incidence-based mortality (IBM) studies (or refined mortality studies). IBM studies include only breast cancer deaths occurring in women with breast cancer diagnosed after their first invitation to screening. Methods We conducted a literature review and identified 20 publications based on IBM studies. They were classified according to the method used for estimating the expected breast…

The Impact of Mammographic Screening on Breast Cancer Mortality in Europe: A Review of Observational Studies
TLDR
From a systematic literature review of European trend studies, the best ‘European’ estimate of breast cancer mortality reduction is 25–31% for women invited for screening, and 38–48% for Women actually screened.
Worldwide Review and Meta-Analysis of Cohort Studies Measuring the Effect of Mammography Screening Programmes on Incidence-Based Breast Cancer Mortality
TLDR
A systematic review and meta-analysis of the estimated effects of both invitation to screening and attendance at screening, with adjustment for self-selection bias, on incidence-based mortality from breast cancer found that breast cancer screening in the routine healthcare setting continues to confer a substantial reduction in mortality.
Breast cancer mortality and screening mammography in New Zealand: Incidence-based and aggregate analyses
TLDR
Breast cancer mortality declines occurring since the advent of screening mammography in New Zealand are consistent with other incidence-based and aggregate studies of screening Mammography in populations, individual-based cohort studies, and randomized controlled trials.
Modern mammography screening and breast cancer mortality: population study
TLDR
Invitation to modern mammography screening may reduce deaths from breast cancer by about 28%, based on the observed mortality reduction combined with the all cause and breast cancer specific mortality in Norway in 2009.
Mortality reductions due to mammography screening: Contemporary population-based data
TLDR
To compare breast cancer mortality in two regions of the Republic of Ireland that introduced a screening programme eight years apart, and to estimate the steady-state mortality deficits the programme will produce, age- and year-matched between-region comparison of breast cancer rates, and of incidence rates of stage 2–4 breast cancer, in the eligible cohorts was carried out.
Breast Cancer Screening, Incidence, and Mortality Across US Counties.
TLDR
It is found that more screening was strongly associated with an increased incidence of small breast cancers but not with a decreased incidence of larger breast cancers, which suggests widespread overdiagnosis.
Overdiagnosis by mammographic screening for breast cancer studied in birth cohorts in The Netherlands
TLDR
This work is the first to quantify overdiagnosis from invasive breast cancer and ductal carcinoma in situ (DCIS) in birth cohorts using an age‐period‐cohort ‐model (APC‐model) including variables for the initial and subsequent screening rounds and a 5‐year period after leaving screening.
Mammography screening: A major issue in medicine.
Screening Mammography & Breast Cancer Mortality: Meta-Analysis of Quasi-Experimental Studies
TLDR
M mammography screening may have modest effects on cancer mortality between the ages of 50 and 69 and non-significant effects for women older than age 70 and results are consistent with meta-analyses of RCTs.
Summary of the Evidence of Breast Cancer Service Screening Outcomes in Europe and First Estimate of the Benefit and Harm Balance Sheet
  • E. Paci

TLDR
The chance of saving a woman's life by population-based mammographic screening of appropriate quality is greater than that of over-diagnosis, and service screening in Europe achieves a mortality benefit at least as great as the randomized controlled trials.

Effect of screening mammography on breast-cancer mortality in Norway.
TLDR
The availability of screening mammography was associated with a reduction in the rate of death from breast cancer, but the screening itself accounted for only about a third of the total reduction.
Service screening with mammography in Northern Sweden: effects on breast cancer mortality – an update
TLDR
This study confirms previous findings in the earlier follow-up and indicates a long-term reduction of breast cancer mortality by 26–30%.
Organised mammography screening reduces breast cancer mortality: A cohort study from Finland
TLDR
The organised mammography screening in Finland is effective and the relationship between the estimates of process and outcome of mammography is not yet straightforward: effectiveness and efficacy remain the best estimates for evaluating the success of Mammography screening.
Reduction in Breast Cancer Mortality from Organized Service Screening with Mammography: 1. Further Confirmation with Extended Data
TLDR
An evaluation of data from breast cancer screening programs in seven Swedish counties indicates a reduction in breast cancer mortality of between 40% and 45% in association with screening, after adjustment for self-selection bias.
Estimating The Benefits of Mammography Screening: The Impact of Study Design
TLDR
Estimated changes in breast cancer mortality following the introduction of routine mammography ranged from a 25% reduction (based on the best methodology) to a 6% increase with a less rigid study design, demonstrating how variations in the analytic approach can affect the conclusions.

TLDR
In the Copenhagen programme, breast cancer mortality was reduced without severe negative side effects for the participants and compared with what the authors would expect in the absence of screening.

Impacts of the Finnish service screening programme on breast cancer rates
TLDR
It is demonstrated that BC screening in Finland is effective in reducing mortality rates from breast cancers, even though the impact on the population level is smaller than expected based on the results from randomised trials among women screened in age 50 to 69.

TLDR
It is confirmed that new treatments and the first rounds of the screening programme contributed to reducing mortality from breast cancer.
Service screening with mammography of women aged 50–69 years in Sweden: effects on mortality from breast cancer
TLDR
A non-significant reduction in mortality from breast cancer was found in counties performing service screening with mammography in Sweden and the results do not contradict the effects found in the Swedish randomised mammography trials.
