What are the auxiliary examination methods for cervical cancer

With the progress of the times, people's living standards are getting higher and higher. While you are enjoying life with your family, have you ever thought about paying attention to some cancers? Although modern technology is advanced, due to the hidden nature of cervical cancer, the symptoms of early cancer patients are extremely unclear. Clinically, most cervical cancer patients have obvious symptoms in the middle and late stages. Here, we remind our friends that even if you are not sick, you should pay attention to it. Even if you don't consider yourself, you should consider your family. The health of your family is your own health.

What are the auxiliary examination methods for cervical cancer?

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 cancer can reach about 98%. Vaginal microscopy can magnify 100 to 300 times. The cervix is ​​stained with 1% toluidine blue to observe the cell structure. Classification and diagnosis can be performed based on the cell morphology, arrangement, size, nuclear size, morphology, color depth, and capillary images.

However, colposcopy cannot replace scraping cytology and biopsy because it cannot detect lesions at the squamous-columnar junction or extending into the endocervical 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 at a distance of 1m. The squamous-columnar junction is fully displayed. No abnormality is negative, abnormality is suspicious, and no squamous-columnar junction is unsatisfactory. It is observed that the diagnostic accuracy rate is 93.1%, so it is a new method with high accuracy, low cost and easy application.

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 cancer, lactate dehydrogenase and hexokinase are significantly increased, especially in those with infiltration, which is helpful for clinical diagnosis.

5. Biopsy of cervix and endocervical canal: All clinical examinations of cervix are important links in diagnosis, but biopsy is the most reliable basis for diagnosing cervical cancer. When the cervical scraping cytology examination is Ⅲ-Ⅳ grade or above, but the cervical biopsy is negative, four-point biopsy should be taken at 6, 9, 12 and 3 points at the junction of cervical squamous column, or multiple tissues should be taken from the unstained area of ​​iodine test and suspected cancerous sites, and sliced ​​for examination, or a small scraper should be used to scrape the endocervical canal and send the scraped material for pathological examination.

The above is the introduction of "What are the auxiliary examination methods for cervical cancer?" When the above symptoms appear, patients should go to a regular hospital for treatment. Early detection and early treatment can effectively cure cervical cancer. People who are related to the pathogenic factors of cervical cancer are advised to take preventive measures for cervical cancer.
