Background: Tumor markers are substances that are produced by cancer or by other cells of the body in response to cancer or certain benign (noncancerous) conditions. Tumor markers are used to help detect, diagnose, and manage some types of cancer. Although an elevated level of a tumor marker may suggest the presence of cancer. Aim: The aim of this review is to compare and analyze the present and newer oncogenic markers which help in diagnosis of different types of cancers. Material & Methods: An extensive literature survey was done aiming to compare and compile cancer tests makers required in diagnosis of diseases. Results: Cytoplasmic Proteins, Cell Surface Antigens, Oncofetal Antigens, Receptors, Oncogenes and their metabolic products, Acute-Phase Proteins, Enzymes, Hormones or Tumor associated antigens such as Carcino-Embryonic Antigen (CEA) and Alpha Feto Protein (AFP) are makers for routine analysis whereas several studies have confirmed and consolidated the usefulness of markers such as AFP: Alfa fetoprotein; β-hCG: Beta human chorionic;gonadotropin; CA: Carbohydrate antigen; CEA: Carcinoembryonic antigen; ER: Estrogen receptor; HIAA: Hydroxy indole acetic acid; LDH: Lactate dehydrogenase; PLAP: Placental alkaline phosphatase; PR: Progesterone receptor; PSA: Prostate-specific antigen. Conclusion: There is no ―universal‖ tumor marker that can detect any type of cancer. Further investigation is necessary to define these biomarkers in terms of usefulness in assessing diagnosing various types of cancers.
