Cancer remains a major cause of death worldwide. Huge research and identification of several markers have resulted in better understanding of its mechanism. Researches focusing on cancer stem cells and their role in metastasis will help the scientific community to propose the therapeutic approaches for treatment of this monstrous disease. Interest of governmental agencies and inter communications of molecular biologists with clinicians can boost the new ideas in identification and characterizations of cancer stem cells. It will also help to elucidate their roles in tumor progression and hopefully would result in better ways to reduce the mortality related to cancer..
