How to detect early cervical precancerous lesions

What tests should be done for cervical precancerous lesions? I believe this is what many female friends want to know, because the examination of cervical precancerous lesions is very important and has great harm. It needs to be discovered early. The earlier it is discovered, the more hope there is for treatment. Let's take a look at how to check for cervical precancerous lesions.

1. Colposcopy: Colposcopy cannot directly diagnose cancer, but it can help select the biopsy site for cervical biopsy. According to statistics, if a biopsy can be taken with the assistance of colposcopy, the diagnostic accuracy of early cervical precancerous lesions can reach about 98%. However, colposcopy cannot replace scraping cytology and biopsy because it cannot detect lesions at the squamous-columnar junction or extending into the cervical canal.

2. Cervical photography: A 10mm microscope with a 35mm camera and a 50mm extension ring is used to form a camera. The image is projected onto a 3.3m wide screen and observed from a distance of 1m. The squamous-columnar junction is fully displayed. If there is no abnormality, it is negative. If an abnormality is found, it is suspicious. If no squamous-columnar junction is found, it is unsatisfactory.

3. Fluorescence examination: It uses the mechanism that cancerous tissue and normal tissue absorb different amounts of fluorescein and display different colors to diagnose whether there is cancer. Cancerous tissue absorbs more fluorescein, and the fluorescence produced is stronger than that of normal tissue and appears dark yellow, while normal tissue appears purple-blue.

4. Tumor biochemical diagnosis: Clinical research by scholars has found that in patients with cervical precancerous lesions, lactate dehydrogenase and hexokinase are significantly increased, especially in those with infiltration, which is helpful for clinical diagnosis.

5. Cervical and endocervical canal biopsy: All clinical examinations of the cervix are important parts of diagnosis, but biopsy is the most reliable basis for diagnosing cervical precancerous lesions.
