Cervical erosion is a physiological phenomenon of the outward migration of the cervical columnar epithelium and is usually asymptomatic. If the cervical opening of erosion is stimulated, such as sexual intercourse, gynecological examination, etc., contact bleeding may occur, the bleeding is small and can be temporarily observed; if the bleeding is large, it is recommended to go to the hospital for examination, cervical TCT, HPV examination, etc., to clarify whether there is chronic inflammation or other lesions, and give reasonable treatment: 1. chronic inflammation: if there is only chronic cervical inflammation, you can give topical pessary, celiac pessary, etc. Drug treatment, prohibit sexual life during treatment, pay attention to personal hygiene; 2, other lesions: for example, atypical hyperplasia, the effect of drug topical treatment is not obvious, you can use cervical microwave or Philips knife, cervical conization and other surgical treatment. It is important for women with cervical erosion to have more contact bleeding, which can easily lead to vaginal infection and increase the chance of developing cervical precancer and cervical cancer, so they need to seek medical attention early, perform vaginal secretion examination and cervical TCT, HPV examination, colposcopy if necessary, and take biopsy for pathology to exclude other cervical lesions and actively treat the disease to avoid delay.
