Cervical CIN grade 1 usually has three outcomes, self-healing mostly in 6 to 12 months; it can also develop into high-grade cervical lesions, and can also develop into cervical cancer. 1. Self-healing: CIN grade 1 patients may subside on their own in 6 months to 1 year, mostly in young women, requiring regular follow-up and close observation, about one-third of the patients can heal on their own, usually without special treatment. 2. High-grade cervical lesions: If HPV infection persists for more than 2 years, CIN1 can develop into high-grade cervical lesions, which requires medication and physical therapy, such as the use of antiviral drugs (interferon), cold knife, laser therapy; for older women without reproductive needs, surgical treatments, such as cervical conization, are also available. 3. Cervical cancer: Continuous infection with high-risk HPV, untimely review, or no standardized treatment, cellular deterioration of cervical epithelial cells occurs, and finally develops into cervical cancer, which requires comprehensive treatment such as surgery, radiotherapy and chemotherapy. Women go to the hospital regularly for cervical cancer screening, including HPV typing test and cervical liquid-based cytology, which can achieve early detection, early diagnosis and early treatment of cervical lesions. Once CIN1 is detected, regular review and close observation are needed.
