Gold standard for diagnosis of cervical precancerous lesions

Cervical precancerous lesions have caused many people to lose their lives. Although the incidence of this disease is not particularly high, its harmfulness cannot be ignored. If everyone can receive treatment early and grasp the best treatment time, the treatment effect can be guaranteed. Before treatment, the disease must be diagnosed first.

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: For patients with cervical smear cytology grade III to IV but negative cervical biopsy, 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 diagnostic methods are relatively professional methods, but this disease generally has no symptoms in the early stages of the disease, so it is not easy for female patients to discover this disease. Therefore, everyone must pay attention to changes in their own bodies, and don't worry if you find problems, but go to a regular hospital for diagnosis and treatment.
