Insulin resistance, hyperinsulinemia and changes in signaling of different hormones associated with diabetes may affect the risk of breast cancer. We reviewed epidemiologic studies of the association between and risk of different types of cancers and the available evidence on the role of certain mediators of an association between diabetes and cancer. Many evidences supports the modest association between type 2 diabetes and the risk of cancer, the mechanisms underlying an association between diabetes and cancer risk remain unclear, particularly because the 2 diseases share several risk factors, including obesity, a sedentary lifestyle. Although the metabolic syndrome is closely related to diabetes and embraces additional components that might influence cancer risk.High-impact journals are those considered to be highly influential in their respective fields. The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
