Revealing the true face of cervical precancerous lesions

What are cervical precancerous lesions? 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.

What are the clinical manifestations of cervical precancerous lesions? Patients with cervical precancerous lesions generally do not show obvious symptoms, or only have symptoms of general cervicitis, such as increased leucorrhea. Some patients also complain of bloody leucorrhea or a small amount of vaginal bleeding after sexual contact. Gynecological examinations show that the cervix is ​​smooth and has no obvious inflammation, or there is cervical congestion or erosion, with varying degrees of erosion and different ranges. It is sometimes easy to bleed when touched, and there is no obvious difference from general chronic cervicitis. Therefore, the clinical manifestations of CIN are not specific. It cannot be diagnosed based on its symptoms and signs alone, and is mainly confirmed based on histological examinations.

Atypical hyperplasia of the cervix is ​​a precancerous lesion. It is reversible, that is, part of the lesion can disappear naturally, but it is also progressive, that is, the lesion can develop and even become cancerous. Its reversibility and progression are related to the scope and degree of the lesion. The possibility of mild atypical hyperplasia disappearing naturally is significantly greater than that of moderate and severe atypical hyperplasia. The possibility of severe atypical hyperplasia developing into cancer is significantly greater than that of mild and moderate atypical hyperplasia. Some scholars also believe that mild atypical hyperplasia of the cervix is ​​a benign abnormal proliferation that can naturally turn to normal.

What are the diagnostic methods for cervical precancerous lesions? 1. TCT cervical thin layer liquid-based cytology. 2. Human papillomavirus HPV test: to identify high-risk groups for further examination. 3. Electronic colposcopy. 4. Cervical iodine test. 5. Cervical and endocervical biopsy. 6. Cervical conization examination. 7. Vaginal cytology.

How to prevent cervical precancerous lesions? 1. Strengthen health education, improve prevention awareness, avoid premature sexual life, and eliminate sexual disorder. 2. Regularly undergo gynecological examinations. Married women are recommended to undergo cervical cytology examinations once a year. If problems are found, further pathological examinations should be performed. 3. For people with cervical lesions and reproductive system infections that have been discovered, especially those infected with human papillomavirus (HPV), corresponding diagnosis and treatment measures should be actively taken to prevent the occurrence and development of cervical cancer.
