Early detection of cancer remains a critical challenge in modern healthcare, significantly influencing patient survival and treatment outcomes. Molecular biomarkers have emerged as powerful tools for identifying malignancies at early stages and enabling personalized therapeutic strategies. This paper reviews recent advances in molecular biomarkers for cancer detection, focusing on genomic, proteomic, and epigenetic markers developed between 2023 and 2025. The study examines their clinical relevance, diagnostic accuracy, and potential integration into personalized medicine frameworks. The findings highlight significant progress in non-invasive biomarker discovery, particularly liquid biopsies and multi-omics approaches, while also identifying limitations related to validation, cost, and clinical implementation. The paper concludes by discussing future research directions and policy implications for integrating biomarker-based diagnostics into routine clinical practice.
