CIN1 clinically refers to low-grade precancerous cervical epithelial lesions, and high-risk HPV infection is the main cause of cervical epithelial lesions, so it is clinically recommended that you should refrain from coitus for 3-7 days after the menstrual period is cleaned up, and choose laser treatment or microwave treatment or cryotherapy, the purpose of treatment is to make the necrotic cervical epithelial lesions and then grow new epithelium to achieve the therapeutic purpose. After treatment, it is important to have regular checkups because there are still high-risk HPV infections, and if they persist, they can still lead to cervical epithelial lesions. However, about 80% of patients with high-risk HPV infections will become negative within a year, so it is important to have regular checkups, but there are no drugs to treat high-risk HPV infections.
