Cervical lesions are a relatively broad concept. Cervical lesions in a broad sense are lesions that occur in the cervical region, such as inflammation, injury, precancerous lesions, tumors, malformations, and endometriosis. Cervical lesions in the narrow sense refer to cervical intraepithelial neoplasia (including cervical carcinoma in situ and cervical atypical hyperplasia) and cervical warts, which can be cured by early detection and can develop into cervical cancer at an advanced stage. Cervical lesion in the broad sense: it may lead to the spread of infection causing chronic pelvic inflammatory disease, pelvic effusion and other diseases, resulting in the accumulation of inflammatory cells, which can also induce female infertility if not cured. The actual cervical epithelial lesions in the narrow sense: 1. or hyperkeratosis, manifesting as abnormal changes in the normal cervical mucosa, which may lead to cell structure destruction and serious malignant tendency if progressed gradually, thus developing into cervical cancer. There are many factors that may lead to the development of cervical lesions, and having had HPV infection is a high-risk factor for cervical lesions. In addition, there is also a relationship with smoking, alcohol and drug abuse. It may also be related to premature, too frequent and unclean sex, and male circumcision, which is unhygienic, can also lead to bacterial infection of cervical lesions. Cervical lesions progress slowly and should be detected and treated early to avoid developing into cervical cancer.
