Can cervical precancerous lesions be detected by B-ultrasound?

If you have cervical precancerous lesions in your life, there are many issues and troubles that patients with cervical precancerous lesions need to pay attention to. Patients with cervical precancerous lesions should not ignore it. There are many people who are susceptible to cervical precancerous lesions. Patients with cervical precancerous lesions should not be too sad. They should pay attention to the treatment methods. So, what are the examination methods for cervical precancerous lesions? The editor will introduce them to you.

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 30%. 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.
