Researches have exhibited that the prognosis of BC is affected by many clinical aspects, such as age, tumor size, histological grade, lymphatic invasion, lymph node, hormone receptor status, etc. However, as the molecular mechanism behind the invasive characteristics of BC is still unclear, it’s crucial to study new biomarkers for forecasting the prognosis of patients and tumor invasiveness. This evidence concerns the gene NR4A1 and neoplasm.
