The article discusses modern ideas about cervical carcinogenesis as a multi-stage process of multifactorial genesis. Currently, ideas about the pathogenesis of cervical cancer (CC) are based not only on understanding the role of high-risk oncogenic human papillomavirus (HPV) in this process and accumulation of genetic changes caused by it, but also on formation of a complex HPV interactome, or a network of intermolecular interactions of HPV oncoproteins with host cell proteins. Carcinogenesis also involves a wide range of epigenetic events and, above all, impairment of the regulatory function of miRNAs. An important role in cervical carcinogenesis is attributed to the concept of cancer stem cells (CSCs) formulated in recent years, which is closely related to the explanation of disease recurrence and treatment resistance, as well as to new approaches to treatment. The cervicovaginal microbiome and cervical microenvironment, which are responsible for natural clearance of HPV, regression of epithelial lesions, and modeling of the immune response, are becoming promising objects for research. The aim of the review was to present up-to-date information on the most important mechanisms of cervical carcinogenesis, as well as on new approaches to the treatment of CC, based, in particular, on the use of knowledge about regulatory miRNAs, CSC markers, and the state of the cervicovaginal microbiota.
