Microbiome and gartynecologic cancer

In recent years more and more studies have pointed out that the microbiota plays an important role in the development of gynecological tumors. A healthy female reproductive tract microbiota is dominated by lactobacilli, which can produce lactic acid and other metabolites to protect the normal reproductive tract microenvironment. If the microflora is out of balance, the abnormally increased flora may contribute to inflammation and even cancer in the reproductive system by activating the immune response, regulating metabolites and hormone levels. In this review, we focus on the relationship between microbiota and three common gynecological cancers, namely cervical, endometrial and ovarian cancers, as well as the significance of microbes in the prevention, diagnosis, and treatment of these cancers, and we introduce the application of multi-omics techniques in microbes; finally, we analyze the common characteristics of microbes in gynecological cancers, and we propose the current challenges and future research directions.
