Functional Genomics Approaches for the Identification of Tumor-Specific Biomarkers

Abstract

Cancer remains one of the leading causes of morbidity and mortality worldwide, with tumors exhibiting complex and heterogeneous genetic profiles that contribute to their progression, metastasis, and resistance to therapy. Early and accurate detection of cancer is critical for improving treatment outcomes, as it allows for timely intervention and better patient prognostication. Traditional diagnostic methods, including imaging and biopsy, often fall short in providing precise information about tumor heterogeneity and molecular characteristics. As a result, there has been an increasing focus on identifying tumor-specific biomarkers that can facilitate early diagnosis, predict treatment responses, and monitor disease progression.
