Thearticle addresses the risk of suffering from breast cancer aftercontracting diabetes. The team of authors chose the meta-analysis of39 primary sources that focused on the identification of theassociation between breast cancer and diabetes. The authors managedto identify that the association between breast cancer and type-1diabetes was statistically insignificant during the pre-menopausalperiod. However, women suffering from type-2 diabetes had a 27 % riskof suffering from breast cancer and 16 % when the risk was adjustedfor the BMI.

Theteam of researchers who co-authored the article are researchers indifferent institutions (such as the international Prevention ResearchInstitute), which indicates that the article is a competent source.The authors held that all articles considered for a review werechecked to ensure that they had no bias, which implies that thearticle is objective. Moreover, the authors describe the procedureused to find the primary sources, implying that the content of thearticle is verifiable. Additionally, the article is relevant to thetopic being considered because it discusses the association betweenbreast cancer and diabetes.

Hardefeldt,J., Edirimanne, S. &amp Eslick, G. (2012). Diabetes increases therisk of breast cancer: A Meta analysis. Endocrine-RelatedCancer,19, 793-803.

Thearticle discusses diabetes as a factor that subject women to the riskof suffering from breast cancer. The purpose of the authors was toestablish the association between breast cancer and diabetes byanalyzing a group of primary studies using a meta-analysis studydesign. After analyzing a total of 43 primary research sources, theauthors found out that the association between breast cancer andtype-1 diabetes was statistically significant among women, butinsignificant among men. After failing to establish the mechanismsbehind the association, the authors concluded that the diabetes couldbe considered as an independent risk factor.

Thetwo authors of the article are researchers at the University ofSydney, which indicates that the article is a competent source. Inaddition, the authors relied on primary sources, which imply thatthey had no control over the quality of the data used in thosesources. However, the procedure for verifying the quality of thearticles was sufficient to guarantee objectivity. Moreover, theprocess of selecting the primary sources as explained properly, whichimplies that the information in the article can be verified.Additionally, the article is relevant because it addresses the issueof the association between breast cancer and diabetes, which is thetopic being considered.

Thearticle addresses the association existing between breast cancer anddiabetes mellitus. The team of authors argues that diabetes mellitusis a risk factor for breast cancer. They achieved the purpose of thearticle by conducting a meta-analysis of 16 credible sources. Theauthors reported that the association between the two diseases wasstatistically significant, where about 23 % of the women sufferingfrom diabetes were likely to suffer from breast cancer. However, theresearchers reported that the association was caused by biologicalprocess that was yet to be discovered.

Theauthors of the article were health care providers at Renmin Hospital,exempt Changhua Wang, who works with the Wuhan University, whichindicates that the article is a competent source. The summaryrelative risk was determined using the random-effect model, whichimplies that the article is objective. In addition, the procedureused to obtain the articles is well laid down, which indicates thatthe information in the article is verifiable. Moreover, the articlecan be considered as relevant to the topic because it addresses theassociation between breast cancer and diabetes.

Liaw,Y., Ko, P., Huang, J., Jan, S., Lung, C., Nfor, O., Chiang, Y., Chou,M., Yeh, L., Tsai, H. &amp Hsiao, Y. (2015). Implications of type-1and type-2 diabetes mellitus in breast cancer development: A generalfemale population-based cohort study. Journalof Cancer,6 (8), 734-739.

Thearticle addresses the association between the two major types ofdiabetes and the risk of suffering from the breast cancer. To achievethe purpose of the article, the authors conducted a cohort studywhere the data of 10,827,079 female patients were obtained fromTaiwanese health care facilities. The researchers identified that theincidence rate for breast cancer among patients with type I diabeteswas 1.110 % and 0.48 % among patients suffering from type-2 diabetes.

Thearticle is a competent source given that it was authored by a team ofresearcher from different institution, such as Chung Shan MedicalUniversity. Selection bias is a common limitation of the cohortstudies, which implies that the authors could not guarantee theobjectivity of the article. However, the procedure followed in thecollecting and analyzing the data was well explained, which impliesthat the content is verifiable. Moreover, the article is relevantgiven that it addressed the same issue (association between breastcancer and diabetes) as the topic being considered.

Tseng,C. (2015). Use of insulin and mortality from breast cancer amongTaiwanese women with diabetes. Journalof Diabetes Research,1, 1-9.

Thearticle discusses the risk of suffering from breast cancer amongwomen who are already suffering diabetes, with a focus on the case ofTaiwanese women. The author conducted a cross-sectional study of48,880 women, who suffered from diabetes. Tseng used a uniqueapproach by studying patients with diabetes, but used insulin as partof their therapy for diabetes. The author identified a positiveassociation between breast cancer and diabetes, went further toconclude that insulin was the underlying cause of breast cancer amongthe diabetic patients.

Thearticle is competent because it was authored a researcher at theNational Taiwan University. Its objectivity is confirmed by the factthat participants were recruited through random sampling, which is areliable strategy that eliminates bias. Tseng explained the entireprocess of recruitment of participants and data collection, whichimplies that the content of the article is verifiable. Moreover, thearticle is relevant given that it was published recently (2015) andit addresses the association between breast cancer and diabetes amongdiabetic patients who use insulin.
