What are the methods for detecting cervical precancerous lesions?

We must actively master the examination methods for cervical precancerous lesions. Only by correctly mastering the examination methods for cervical precancerous lesions can we make an accurate diagnosis and treatment. Next, we will give a detailed interpretation of the examination methods for cervical precancerous lesions.

Cervical smear cytology examination: This method can detect precancerous lesions and early cervical precancerous lesions. Due to the false negative rate, patients should have regular examinations.

Iodine test: Normal cervical and vaginal squamous epithelium are rich in glycogen and can be stained brown by iodine solution, while cervical erosion and abnormal squamous epithelial areas (including atypical hyperplasia, carcinoma in situ and invasive carcinoma) do not have glycogen and will not be stained.

Biopsy of cervix and endocervical canal: If the cervical smear cytology examination is grade III to IV, but the cervical biopsy is negative, multiple tissues should be taken for pathological examination.

Colposcopy: Colposcopy cannot directly confirm whether there is cancer, but it can assist in biopsy of the cervix. According to statistics, the diagnosis rate of early cervical precancerous lesions is as high as about 98% when biopsy is 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 according to the specific situation.

The above-mentioned methods for checking cervical precancerous lesions are methods that have been tested in practice and are relatively effective. Don’t ignore them. Of course, after you have mastered the methods for checking cervical precancerous lesions, you must actively go to a professional hospital to treat the disease to avoid the occurrence of disease hazards.
