The diagnosis of cervical cancer is a more complex process and there is no 1-minute self-test for cervical cancer. Staging needs to be evaluated during the examination of cervical cancer, which can be very helpful for subsequent treatment. Usually, detailed whole body examination and gynecological examination will be conducted, and cervical masses will be taken for biopsy, as well as auxiliary examinations in the form of X-ray, abdominal ultrasound, CT, etc.: I. Physical examination: 1. Whole body examination: it is necessary to check the condition of the patient’s skin and whether there are enlarged lymph nodes in the whole body, especially those in the supraclavicular and inguinal regions. Check the abdomen for pressure pain, rebound pain, muscle tension and abdominal distension, intestinal sounds, etc.; 2. Gynecological examination: mainly through vulvar examination to check whether there is tumor invasion or human papilloma virus infection lesions in the vulva, ectopic patients can see cauliflower-like superfluous organisms in the cervix, and can check whether there are lesions in the cervical area through a speculum, endogenous patients can see cervical hypertrophy, hard texture, and superfluous organisms can be seen when the vaginal wall is invaded. When the vaginal wall is invaded, the growth of redundant organisms can be seen. When the parametrial tissue is invaded, thickening, nodularity and hardness of the parametrial tissue can be detected by double and triple diagnosis. Laboratory examination: Blood can be drawn to check cytokeratin fragment 211 and squamous cell carcinoma antigen, carcinoembryonic antigen, methemoglobin, cancer antigen markers, etc. to assist in confirming the diagnosis, and HPV testing can also be used to screen for cervical cancer. C. Biopsy: Use a small brush-like sampler to collect cervical exfoliated cells for cervical cytology to detect whether precancerous lesions or cancer cells are present. Biopsies of the cervix and cervical canal can also be taken through cervical canal scratching, colposcopy and conical hysterectomy for examination. Imaging examination: X-ray, abdominal ultrasound, CT and MRI can be used to help doctors determine the extent of tumor invasion, size, whether distant metastasis occurs and the location of metastasis. In addition, iodine solution can be applied on the mucous membrane of cervix and vagina to observe the staining. Usually when there is no staining, it proves that inflammation or lesions are present here and a tissue biopsy is needed. Women with abnormal vaginal bleeding, especially after sexual intercourse, are advised to seek medical examination as early as possible to help the prognosis with early treatment. In addition, for women with a history of sexual intercourse, regular medical checkups are recommended to detect lesions earlier and treat them as early as possible to reduce the chance of cancer.
