Introduce some issues about cervical precancerous lesions

What exactly are cervical precancerous lesions? Cervical cancer is no longer a simple minor disease. It is very harmful to women. If not treated in time, it will cause cervical precancerous lesions. So what are cervical precancerous lesions? Let's learn about it together below.

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. 70% of 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.

4. Mixed blood in leucorrhea. In addition to uterine bleeding caused by IUD insertion, women with mixed blood in leucorrhea for a long time should be checked in time.

Diagnosis of cervical precancerous lesions:

1. Cervical cytology examination

(1) Pap smear: This is a traditional cervical cytology test. Its widespread use has successfully reduced the incidence and mortality of cervical cancer by about 70% in the past 50 years. However, due to the high false negative and missed diagnosis rates of Pap smear, it no longer meets the needs of today's medical services and is gradually being replaced by more advanced examination methods.

(2) TCT Cervical Thin-Layer Liquid-Based Cytology: It is a new cytological technology invented in the late 1990s. It can significantly improve the detection rate of cervical cancer and precancerous lesions and is the most widely used cervical cytology examination method in the world.

2. Human papillomavirus (HPV) testing: to identify high-risk groups and conduct further examinations.

3. Electronic colposcopy examination.

4. Cervical iodine test.

5. Biopsy of the cervix and endocervical canal.

6. Cervical conization examination.
