Cervicitis is divided into acute cervicitis and chronic cervicitis, in which the long-term presence of chronic cervicitis may be associated with the risk of cancer. Cervicitis is an inflammation of the mucous membrane of the cervical canal. Infection by pathogens such as Chlamydia trachomatis and Neisseria gonorrhoeae results in congestion and edema of the cervix, even with hyperplasia of the cervical glandular epithelium and mesenchyme, and chemosis of the squamous epithelium, which is closely associated with the development of cervical cancer. The immature squamous epithelium is metabolically active and may end up with abnormal cell proliferation, poor differentiation, disorganized arrangement, abnormal nuclei, increased mitosis, and finally cervical cancer. The presence of cervicitis reduces the resistance of the cervix, making it susceptible to human papilloma virus (HPV) infection, which is an important factor in the development of cervical cancer. HPV accelerates the heterogeneous proliferation of cells and causes cervical cells to become cancerous. In conclusion, cervicitis increases the risk of cancer, so in order to prevent cervical cancer from evolving into cervical cancer, it is necessary to pay attention to pubic hygiene, avoid unclean sex, avoid cervicitis and infection with human papilloma virus, and if cervicitis occurs, timely treatment should be carried out to prevent long-term cancer.
