Beyond genetic alterations, the tumour microenvironment, including the vaginal microbiota, plays a decisive role in tumour progression. Recent studies have highlighted the involvement of microbial imbalance \u2018dysbiosis\u2019 in ovarian carcinogenesis, particularly through interactions with the immune system and the modulation of local inflammatory pathways such as Th17\u2010related pathways. In a state of \u2018eubiosis,\u2019 the vaginal microbiota, dominated by\n                    <jats:italic>Lactobacillus<\/jats:italic>\n                    species, plays a protective role by producing lactic acid, maintaining an acidic pH, and preventing infections. Conversely, dysbiosis, characterised by a decrease in lactobacilli and an increase in opportunistic bacteria such as\n                    <jats:italic>Gardnerella<\/jats:italic>\n                    ,\n                    <jats:italic>Atopobium<\/jats:italic>\n                    and\n                    <jats:italic>Prevotella,<\/jats:italic>\n                    promotes chronic inflammation through Toll\u2010like receptor signalling, stimulates the production of IL\u20106, IL\u20108 and TNF\u2010\u03b1, thereby creating a pro\u2010tumour immune microenvironment conducive to tumour development. The complex interactions of the microbial flora, mucosal immunity, and tumour cells could explain the association between vaginal microbiota and ovarian cancer. This review highlights these mechanisms and emphasises the potential of vaginal microbiota as a tool for early detection and improved diagnosis of ovarian cancer. A better understanding of this microbe\u2010host dialogue could pave the way for new prevention and detection strategies.\n
