Evidences of the current research say that cancer is multi-factorial with varied mechanisms of origin. Globally, it is the second most dominant factor for human death. Most theories disclosed that either intrinsic (genetic) or extrinsic factors were responsible for the cancer development. The cells being triggered by these factors may be somatic (differentiated functional cell) or a normal stem cell with multi-potency or even the transient proliferative cells derived from the stem cells. These stem cells possess several features like slow cell cycle, ability to extrude chemotherapeutic drugs, exhibit epithelial mesenchymal transition and inhibit apoptosis. It is known to play an important role in cancer progression and recurrence. However, the origin of these cancer stem cells still remains debatable.
