Breast cancer is second most prevalent type of cancer and is equally common in developing as well as developed countries (American cancer Society, 2013). Despite favorable survival in developed countries, the most frequent cause of cancer deaths in women is still breast cancer, in developed as well as in developing countries (GLOBOCAN: International Agency for Research on Cancer, 2008). The treatment expenditure of breast cancer is a burden not only for people diagnosed with cancer but also for their families and society as a whole. 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.
