Publisher's Synopsis
Cancer is defined as the gradual accumulation of gene alterations that transform any human cell into a mass of uncontrollable proliferation (1). Specifically, breast cancer (BC) is among the leading causes of death worldwide, including Mexico (2). In recent years it has been observed that there is a close relationship between breast cancer and some factors such as: a) socioeconomic factors, b) body mass index, c) diet, d) early age of first pregnancy, e) not having breastfed and f) high breast density. However, none of these factors have been able to explain the possible causes or the development of breast cancer; consequently, there has only been a slight decrease in the incidence of this cancer, and it has been reported that timely diagnosis of breast cancer would allow for better treatment and prognosis for the patient.
