Câncer de mama e abordagens diagnósticas: novas perspectivas com Biossensores

Abstract

According to the World Health Organization (2020), breast cancer is the second most diagnosed type of cancer and the fifth leading cause of death globally. Characterized by a group of epithelial tumors with a high invasive and metastatic capacity, breast carcinoma has focused significant attention on improving early diagnosis and treatment. In fact, in the last few decades, there has been a significant improvement in diagnostic methods for identifying and assessing cancers' progression. Thus, the present study aimed to carry out a bibliographic survey on diagnostic medicine applied to breast cancer, including new perspectives. The results showed a significant variety of clinical and physical examinations, ranging from radiography and biopsies to the detection of tumor markers and genetic tests. To improve earlier detection, already known biomarkers and a new potential class of molecules called microRNAs are being associated with biosensor technology, which may contribute in the future, more straightforwardly, with the determination of prognosis, diagnosis, and even monitoring of patients undergoing treatment.
