Molecular markers in cancer.

Cancer remains a common health issue having significant socioeconomic burden worldwide. Despite the awareness campaigns, cancer cases continue to increase due to an aging population and lack of early detection biomarkers. Accordingly, much research has focused on non-traditional approaches which include novel imaging modalities and liquid biopsy. In addition, a considerable number of biomacromolecules as well as other biomarkers have been identified to further explore their potential use as diagnostic, prognostic and therapeutic tools. In this review, we provide an update on these new findings and explore their clinical application in cancer.
