The most valuable auxiliary examination for cervical precancerous lesions

In recent years, the incidence of cervical precancerous lesions has been increasing. The occurrence of cervical precancerous lesions seriously endangers the normal life of female friends. Therefore, once we find the symptoms of cervical precancerous lesions, we must check and treat them in time. So how do we check for the occurrence of cervical precancerous lesions in life? Let us learn about it together.

The main methods for detecting cervical precancerous lesions are:

Iodine test: Normal cervical and vaginal squamous epithelium contains abundant glycogen, which can be stained brown by iodine solution, while cervical erosion and abnormal squamous epithelial areas (including atypical hyperplasia, carcinoma in situ and invasive carcinoma) have no glycogen and will not be stained. This is the main method for detecting cervical precancerous lesions.

Cervical and endocervical canal biopsy: Cervical smear cytology examination is effective. However, if the cervical biopsy is negative, multiple tissues should be taken for pathological examination of cervical precancerous lesions.

Cervical smear cytology examination: This method of examining cervical precancerous lesions can detect precancerous lesions and early cervical precancerous lesions. Because there is a false negative rate of 5%-10%, patients should have regular examinations.

Colposcopy: Colposcopy cannot directly confirm whether a person has cancer, but it can assist in the biopsy of cervical precancerous lesions. 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.

Cervical cone excision: When biopsy cannot confirm the presence of invasive cancer, cervical cone excision can be performed. After the diagnosis of cervical precancerous lesions, lymph node angiography, cystoscopy, and colonoscopy can also be performed for the examination of cervical precancerous lesions, depending on the specific situation.

The above is a detailed introduction to the examination methods of cervical precancerous lesions. I believe that everyone has a detailed understanding. For our health, if we find symptoms of cervical precancerous lesions in our lives, we must promptly check and treat them, so as to stay away from the troubles of cervical precancerous lesions!
