Bacterial infections associated with cancer: possible implication in etiology with special reference to lateral gene transfer.

Bacteria are capable of exchanging DNA between each other and even from other organisms including human, but what will be the fate of such exchange? Enigmatic association between bacterial infections and cancer is also demonstrated recently with unknown exact cause and effect mechanism. This enigma may be resolved not in all but in few cases with the view of horizontal DNA transfer. The present article tries to examine this association in the frame of new idea. This article concludes that knowledge of this association may aid in management of cancer in clinical settings.
