Human Papillomavirus and Other Relevant Issues in Cervical Cancer Pathogenesis

. As a result, chronic infections with unfavorable microorganisms (other than HPV) may affect the pathological processes of malignancy. On the other hand, the cervix is an estrogen-sensitive organ like the corpus uteri (i.e., the body of the uterus). Estrogen and different estrogen receptors are implicated in the development and promotion of various cancers, including endometrial cancer. A number of reports also suggest a close association between estrogen and HPV in the development of cervical cancer. Furthermore, estrogen is linked with the characteristics of the vaginal microenvironment including bacteria. Therefore, several of the abovementioned factors (some are preventable) could play an important role in the progression of cervical neoplastic lesions.
