Screening methods for cervical cancer include: TCT examination, HPV examination, colposcopy and cervical biopsy. 1. TCT examination: that is, cervical cytology examination, which is the main method of cervical cancer screening, detecting pre-cancerous cervical lesions by examining the morphology of cervical exfoliated cells; 2. HPV examination: the chance of cervical cancer increases in patients with HPV infection, and HPV is usually examined at the same time during TCT examination; 3. Colposcopy: localized cervical lesions can be observed. If abnormalities are found in TCT and HPV examination, biopsy should be performed under colposcopy for pathological examination; 4. Cervical biopsy: some cervical lesions exist in the cervical canal, TCT, HPV and colposcopy can not make a clear diagnosis, and it is necessary to carry out cervical conization or puncture biopsy and send it to pathological examination for a clear diagnosis. Cervical cancer is a common gynecological malignant tumor, early symptoms are not obvious, regular screening is important. If cervical cancer is diagnosed, it is necessary to go to regular hospitals for timely consultation and comprehensive treatment to avoid delaying the condition.
