Concentrating on molecular biomarkers in cancer research, Cancer Biomarkers publishes original research findings and reviews solicited by the editor on the subject of the identification of markers associated with the prevention, detection, diagnosis, and treatment of cancer whether or not they are an integral part of the pathological lesion. The disease markers may include, but are not limited to, genomic, epigenomic, proteomic, cellular and morphologic, and genetic risk factors predisposing to the disease or indicating the occurrence of the disease. Manuscripts on these risk factors or biomarkers, either in altered forms, abnormal concentrations or with abnormal tissue distribution leading to disease causation, will be accepted. Data science, artificial intelligence, radiomics, and other molecular approaches, such as bulk and single cell genomic sequence analyses for biomarkers discovery, development, and validation in reference to cancer prevention and treatment, will also be accepted.
