What tests can accurately detect cervical precancer?

The appearance of cervical precancerous lesions threatens women's health, so we cannot relax our vigilance against cervical precancerous lesions. After suffering from this disease, we should find out the cause of cervical precancerous lesions through the examination of cervical precancerous lesions. Let's take a look at the inspection measures!

1. Colposcopy: When abnormalities are found in the cervical cytology smear examination, a colposcopy is required to confirm the lesion. If necessary, several pieces of tissue can be taken for pathological examination to provide a basis for surgical treatment.

2. Cervical cone biopsy: Before cervical cone biopsy, colposcopy should be performed to determine the location of the lesion. The excised specimen should be subjected to continuous pathological sections to exclude external infiltration.

3. Cervical biopsy under iodine test: Normal cervical and vaginal squamous epithelium is rich in glycogen and can be stained brown by iodine solution, while atypical squamous epithelial hyperplasia, carcinoma in situ and invasive carcinoma do not have glycogen and therefore do not stain. Biopsy in the iodine-unstained area can improve the accuracy of screening for early cervical precancerous lesions.

4. Cervical TCT test: It uses a liquid-based cell detection system to detect cervical cells and perform TBS cytological classification diagnosis, which greatly improves the satisfaction of the specimen and the detection rate of abnormal cervical cells, and significantly improves the diagnosis rate of cervical precancerous lesions, especially precancerous lesions.

5. HPV test: It is internationally recognized that HPV infection is the main cause of cervical precancerous lesions and precancerous lesions. 99.8% of patients with cervical precancerous lesions can be infected with HPV virus. The specimen collection is simple, non-destructive and painless.

The above five methods are commonly used to check for cervical precancerous lesions. When suffering from cervical precancerous lesions, patients should not have too much psychological pressure, but should actively seek treatment with the help of doctors. I hope that patients with cervical precancerous lesions can recover soon.
