Abstract: Breast cancer (BC) is a group of genetic disorders characterized by a high level of molecular and cellular complexity that causes malignant tumors, affecting the majority of women in the world. Despite the health measures taken to control it, the incidence and mortality of this malignancy are still on the rise. Triple-negative breast cancer (TNBC) is a heterogeneous molecular subtype of breast cancer that is characterized by being negative for estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor (HER2). It represents about 15% of BC worldwide and shows aggressive patterns with limited therapeutic options and a poor prognosis. For this reason, research is being carried out to find early and accurate diagnostic and prognostic markers. The discovery of microRNAs (miRNAs) has led to new approaches to understanding cancer biology. miRNAs are stable molecules capable of controlling messenger RNAs (mRNAs), which, besides being present in tissues, are also found in body fluids such as blood. A series of studies have shown that miRNAs regulate of carcinogenesis, which means tumors formation and cancer progression mechanisms such as metastasis, among others.
