There is no accurate self-exclusion method for cervical cancer. Usually, patients can consider whether they have the disease based on whether they have relevant clinical manifestations, but such exclusion or diagnosis is not standardized. Patients with early stage cervical cancer often have no obvious symptoms and signs, which may lead to missed diagnosis and misdiagnosis, and often need auxiliary examination to make a definite diagnosis. Therefore, if you want to know your health status or if you have uncomfortable symptoms, you should actively go to hospital for medical consultation.1.Cervical cytology examination: it is the basic method for early cervical cancer screening, with higher specificity but slightly lower sensitivity, mainly using Pap smear or liquid-based cell smear method.2.HPV test: with higher sensitivity but lower specificity, it is often combined with cytology examination to determine the presence of HPV infection. Colposcopy: Colposcopy is recommended for those with abnormal cytology or HPV test; 4. Cervical biopsy: Histological diagnosis is the basis for confirmation. Any suspicious lesion with naked eyes or colposcopic diagnosis of high-grade lesion should be biopsied to help confirm the diagnosis as early as possible. Suspicious symptoms of cervical cancer include vaginal bleeding and vaginal drainage, etc. If such symptoms are present, early medical attention should be sought. Cytology and/or HPV testing, colposcopy, and biopsy are the “three-step” diagnostic procedure for cervical cancer, which is of great importance. After the diagnosis is confirmed, ultrasound or CT, intravenous pyelogram, cystoscopy and proctoscopy can be chosen according to the specific situation to further understand the tumor growth and then formulate the treatment plan.
