Biomarkers are naturally occurring molecule, gene or characteristic feature used to indicate the normal or abnormal processes taking place in our body. Its presence also acts as an indicator of a certain disease or illness. They can be patterns of gene expression, levels of particular proteins or the presence of an antigen e.g.(Prostate Specific Antigen-PSA in the case of prostate cancer). They can be found in the blood, stool, urine, tumor tissue, or other tissues or bodily fluids. They can be evaluated either by biopsy or by some imaging techniques. Cancer biomarkers or tumor markers are mostly proteins produced by cancer cells or other cells in response to cancer. The detection and measurement of biomarkers help in finding the specific anticancer treatment method for a particular person.
