Breast Cancer Biomarker Discovery: Proteomics and Genomics Approaches

Breast cancer is one of the major health problems of the Eastern world. Regardless of the survival rate improvement with progression in screening and adjuvant systemic therapies, still one – third of the patients with primary breast cancer have recurrence of micro metastasis after 10 years. It is important to discover a reliable biomarker for detection of breast cancer. The underlying molecular mechanism of the disease needs to be better understood. Allied to genomics, proteomics technologies promise to be valuable for identifying new markers that improve screening, early diagnosis, prognosis and prediction of therapeutic response or toxicity, as well as the identification of new therapeutic targets. In this review, we present proteomic and genomic sciences have been used for differential analysis of breast cancer to find molecular changes of cancer for detection candidate biomarkers.
