Cervical precancerous lesions refer to lesions that occur in the area before cancer occurs and thus cause cancer. Cervical precancerous lesions are atypical cervical hyperplasia. The occurrence and development of cervical cancer has a gradual evolution process, which can take from several years to decades. It is generally believed that this evolution process goes through the following stages: hyperplasia, atypical hyperplasia, carcinoma in situ, early invasion, and invasive cancer.

Symptoms of cervical precancerous lesions:

1. Bleeding after sexual intercourse. Many cervical cancer patients have this symptom.

2. Cervical erosion. Young women with long-term untreated cervical erosion, or those who still have cervical erosion after menopause, should pay attention to it.

3. Bleeding after contact, bleeding after sexual intercourse, or uterine bleeding after gynecological examination are all signs of cervical precancerous lesions.
