What to check for gynecological cervical precancerous lesions

Cervical precancerous lesions are very difficult to treat. The occurrence of cervical precancerous lesions will cause damage to the patient's physical health and mental health. Cervical precancerous lesions are very serious and difficult to control. Therefore, we need to learn more about cervical precancerous lesions so that we can make the right judgment when treating cervical precancerous lesions. What are the examination items for cervical precancerous lesions so that everyone is no longer unfamiliar with it.

1. Iodine test for cervical precancerous lesions: Normal cervical and vaginal squamous epithelium are rich in glycogen and can be stained brown by iodine solution, while cervical erosion and abnormal squamous epithelial areas (including atypical hyperplasia, carcinoma in situ and invasive cancer) have no glycogen and will not be stained.

2. Biopsy of cervix and endocervical canal: If the cervical smear cytology examination is grade III to IV, but the cervical biopsy is negative, multiple tissues should be taken for pathological examination.

3. Cervical smear cytology examination: This examination item for cervical precancerous lesions can detect pre-lesions and early cervical precancerous lesions. Due to the false negative rate, patients should have regular examinations.

4. Colposcopy: Colposcopy cannot directly confirm whether a person has cancer, but it can assist in the biopsy of the cervix. According to statistics, the diagnosis rate of early cervical precancerous lesions is as high as 98% when biopsies are taken with the assistance of colposcopy.

5. Cervical cone resection: When biopsy cannot confirm the presence of invasive cancer, cervical cone resection can be performed. After the diagnosis of cervical precancerous lesions, lymph node angiography, cystoscopy, proctoscopy and other cervical precancerous lesions examination items can also be performed according to the specific situation.
