It takes about 1-2 years for cervical precancerous lesions CIN1-CIN2 to be detected, and this time varies due to individual differences. When precancerous cervical lesions CIN1 are detected, appropriate treatment should be given, such as laser treatment, microwave treatment, or cryotherapy to make the lesion tissue necrotic and fall off, and then grow new tissue to achieve the purpose of treatment. If left untreated, CIN1 may turn into CIN2, or into normal epithelial tissue, but if you take a chance, it is unlikely that all of it will turn into normal tissue, so it is important to actively treat CIN1 to avoid the development of CIN2 and the need to do a conical cervical resection, which would result in even greater damage.
