Up to 20% of all cases of cancer are associated with microbial infection. In addition to the common sense of pathogenic bacteria, viruses and fungi, however, human microbiome, which is called the second genome of human body and has long been thought to coexist peacefully with us, may play an important role in the process of carcinogenesis. The illumination of the potential relationship of oral and gut microbiome with cancer, and its mechanism of tumorigenesis, such as microbial infection, activation of procarcinogens and interference in human cell signaling, may provide the clues for seeking the new target and therapy of cancer. In this paper, we reviewed the latest progress of t
