What are the diagnostic indicators for cervical precancerous lesions?

For diseases like cervical precancerous lesions, early detection and early treatment are necessary so that patients can recover faster and avoid dying from the disease. This disease must not be misdiagnosed. Misdiagnosis will cause great trouble to the treatment. Therefore, diagnosis is very important. So, what are the diagnostic methods for the cervix? Please see the introduction below.

1. Cervical and endocervical biopsy

When the cervical smear cytology diagnosis is grade III to IV or above, but the cervical biopsy is negative, four-point biopsies should be taken at 6, 9, 12 and 3 o'clock at the junction of the cervical squamous and columnar parts, or multiple tissues should be taken from the unstained area of ​​the iodine test and the suspected cancerous site, and a section diagnosis should be performed, or a small curette should be used to scrape the endocervical canal and the scrapings should be sent for pathological diagnosis.

2. Colposcopy diagnosis

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 help of colposcopy, the diagnostic accuracy of early cervical precancerous lesions can reach about 98%. However, colposcopy cannot replace scraping cytology diagnosis and biopsy, and cannot detect lesions in the cervical canal.

3. Cervical Conization

When the biopsy is uncertain about the presence of invasive cancer, cervical cone excision can be performed. However, diagnostic cervical cone excision is rarely used nowadays. When the cervical precancerous lesions are confirmed, lung radiography, lymph node angiography, cystoscopy, and colonoscopy can be performed according to the specific situation to determine the clinical stage of cervical precancerous lesions.

4. Cytological Diagnosis

Cytological diagnosis is a common and important diagnostic method for cervical precancerous lesions. This method is also called cervical smear diagnosis in clinical practice. It mainly involves taking cell samples from suspected lesions of the cervix, making smears, and then diagnosing under a microscope to find cancer cells.

The above is the expert's introduction to the diagnosis method of cervical precancerous lesions. I hope it will be helpful for your future diagnosis. The diagnosis of cervical precancerous lesions is very important, so you should also understand what the diagnosis methods are. When you go to the hospital for diagnosis, you will also know what method you are using.
