This article by Autier et al. (2011) looks into the contributions of mammography in decreasing the mortality rates in breast cancer patients. The authors assessed the trends of cancer cases where screening was practiced for a minimum of 7 years. The criterion used for assessment of advanced cancer cases was the tumor size, and in cases where this data was not available, the authors used the spread to distant and other regional sites. A systematic research was conducted and data collected from the USA, Northern Ireland, Tasmania, and Scotland. According to the findings, areas that had a widespread and sustained mammographic screening of advanced cancer incidence did not support any considerable role for screening in the pursuit for decreasing mortality. This article is important in this study because it looks into the contributions of mammography in reducing mortality rates in advanced cancer patients.

The article by Bleyer & Welch looks into the effect mammography has had on breast cancer patients. The authors used epidemiology, surveillance and end results data for trends beginning from 1976 to 2008. The data was for both early incidences and late-stage breast cancer for women at the age of forty years and above. From the findings, the authors concluded that despite early screening of breast cancer patients, mammography only reduced the rates at which women present advanced cases of breast cancer. However, the authors were not certain on the numbers of women affected which showed an imbalance and a substantial overdiagnosis. They also concluded that screening had a slight effect on the mortality rates from breast cancer. This article is important for this study as it looks at the effects mammography screening of breast cancer patients has on mortality rates.

The impact of mammographic screening on breast cancer mortality in Europe: a review of observational studies. Journal of medical screening, 19(1_suppl), 14-25.Broeders et al. (2012) in their article assessed the impact of mammography screening on mortality rates of breast cancer patients in Europe. A systematic review of the literature was conducted for both women that were screened versus those that were not screened. The CC studies, as well as the IBM studies, were individually pooled through the use of random meta-analysis effects. From the findings, the authors observed that the estimated breast cancer mortality decrease for women who were invited for screening was between 25-31%. Consequently, for those women who were actually screened the rates were between 38-48%. Further, the authors concluded that the controversy on mammography breast cancer screening is due to unsuitable methodological approaches that are not able to show the true effects of the screening. The article is important for this study as it shows the impact mammography screening has on mortality rates for cancer patients.

Gotzsche, P. C. (2011). The relation between breast cancer mortality and screening effectiveness: a systematic review of the mammography trials. Dan Med Bull, 58(3), A4246.Gotzsche (2011) assessed mammography screening trials which according to the research, they had varied results. According to this study Gotzsche (2011) also found out that screening was conducted in a better way than in others, and for this reason, the diagnosis was not correct in some cases. If the screening was done in a better way, more cancer cases would have been identified earlier and few could have reached the advanced stage. For the research, a systematic review was conducted on the trials through the use of meta-regression. From the research, a 16% reduction in mortality rates for screening effectiveness that was zero was predicted, but this could only occur if there was a bias. This led to the conclusion that differences in breast cancer mortality cases could not be explained by looking at the differences in the mammographic screening effectiveness. The article is important for this research as it examines the effects of screening on the mortality rates of breast cancer patients.

International journal of cancer.This article by van den Ende et al. (2017) shows the importance of early detection of breast cancer in lowering the mortality rates. There has been a debate among the western countries on the recommended age for mammography screening. In this article, the authors through the use of systematic review of the literature looking into the harms and benefits of mammography screening in women between the ages of 40-49 years. From the findings, there was no significant effect observed on the mortality rates of breast cancer patients. From the randomized trials extension of mammographic screening was not recommended for younger people. This article is important for this study because it looks into the recommended age group for mammography screening.
