A biopsy result of CIN grade 1 usually does not require surgery and regular follow-up is sufficient. CIN grade 1 refers to low-grade intraepithelial neoplasia of the cervix, which belongs to the mildest type of cervical precancerous lesion and is caused by high-risk HPV infection. About 60% of low-grade precancerous lesions will regress naturally, with a cytology of CIN grade 1, and can be followed up with observation only. During the follow-up process, treatment is appropriate if the lesion develops or persists for two years, which may include laser freezing, cervical conization if it develops into a high-grade precancerous lesion, or hysterectomy if the patient is older and does not have fertility requirements. Cervical biopsy results of CIN grade 1, generally do not need surgical treatment, but must be closely and regularly follow up, if the disease progresses timely treatment. Attention to regular review, can be detected as early as possible, early treatment, to avoid delays in the condition.
