The human microbiota typically contains symbionts and supports the host, although it can be commensal or reciprocal and pathogenic in its host function, immunity, and diet. Modern studies indicate that perturbations in the microbiome may be present in quite a few diseases, including inflammation and cancer. To be more specific, changes in the microbiomes of the gut and vagina may be related to various gynecologic cancers (cervical, uterine, and ovarian). Furthermore, the gastrointestinal microbiota can be altered by environmental factors and pre-existing morbidities and may cause nausea, vomiting, diarrhea, constipation, bloating, and abdominal pain. A healthy female gut microbiome is dominated by Bifidobacterium, Lactobacillus, Bacteroides, Clostridium, Escherichia, Streptococcus, and Ruminococcus; the vaginal microbiome includes Firmicutes, specifically Lactobacilli spp. However, the gram-variable coccobacillus Gardnerella vaginalis (previously known as Haemophilus vaginalis) dominates the microbiota of biological vaginosis (BV) and includes several anaerobic organisms. Vaginal microbiota perturbations can cause vaginal pain, sexual dysfunction, and urinary symptoms. In the current review paper, we explore recent research along with existing gaps in knowledge related to the association of changes in microbiota diversity and the pathogenesis of vaginal infection-associated cervical cancer.
