The main indicators of cervical cancer are still the examination of the cervix and cervical canal tissues. There are obvious cancerous changes, and under the microscope pathological sections can show tendencies of cell carcinogenesis, or already developed cancer. The second is the cytological examination of cervical scrapings, which detects the presence of cancer cells. The third is the iodine test, where areas that do not stain after iodine staining indicate a lack of glycogen in the epithelium, suggesting possible lesions. The fourth is colposcopy, which may reveal suspicious cancerous areas, allowing for biopsy to confirm cancer cells. The fifth includes ultrasound, CT, MRI, etc., which can detect mass occupying lesions, all of which are indicators of cervical cancer. Of course, abnormalities in tumor markers are also considered, but the main reliance is still on the indicators from pathological examinations to determine if it's cervical cancer.
