When we think about the human papillomavirus (HPV), we often focus on its link to cervical cancer. However, this review looks at how HPV interacts with the local environment in the mouth, anus, and genitals. The researchers found that the types of bacteria living in these areas can change significantly when a person is infected with HPV. These changes depend on factors like the person's sex, race, and specific population.
In the mouth, a specific three-part link exists between gum inflammation, high-risk HPV, and a common yeast called Candida albicans. This combination can increase the risk of oral cancer. In the genital and anal areas, certain bacteria can build up in lesions caused by HPV. The research also noted that having other infections, like HIV or other sexually transmitted infections, can make these bacterial imbalances worse and help the virus stay in the body longer.
While these findings are based on a review of existing data rather than a new clinical trial, they offer a new way to look at prevention. By understanding how these bacteria and viruses work together, doctors may eventually find new ways to use the microbiome to prevent cancers in the mouth and genital areas.
