Cervical cancer has a high incidence rate among the three major malignant tumors of women in China, but due to the screening of cervical cancer in recent years, the so-called cervical cancer is found in the early stage, and after timely treatment, the survival rate of 5 years is very high. However, the early stage of cervical cancer often has no obvious symptom, and if the lesion is progressing, it can show the following symptoms: 1) Vaginal bleeding: it usually manifests itself as contact bleeding after sexual life or vaginal bleeding after gynecological examination after visiting the hospital. Irregular vaginal bleeding may be manifested as irregular menstrual cycle, prolonged menstrual period, increased menstrual flow, etc. There are also some elderly patients who may have irregular vaginal bleeding after menopause; 2. Vaginal discharge: it may be manifested as blood in leukorrhea, bloody leukorrhea, or rice slop-like or fishy-smelling vaginal discharge, and it may be accompanied by local infection. If accompanied by local infection, there may be purulent and foul-smelling leukorrhea; 3. Secondary symptoms: with the progress of cervical cancer, if it reaches the advanced stage of cervical cancer, there will be secondary symptoms accordingly, such as the cancerous foci of cervical cancer oppressing the ureter, which will cause the symptom of obstruction of the ureter, causing pyelonephrosis, or even renal failure, uremia, etc. If the cancerous foci of cervical cancer appear to be in the advanced stage of cervical cancer, the symptoms of ureteral obstruction will be caused. If cervical cancer lesions cause heavy vaginal bleeding, it will lead to anemia, and in the late stage, it will lead to cachexia, which is a consumptive symptom, etc. Therefore, if these abnormal symptoms appear, it will be very difficult for the patient to get rid of them. Therefore, if these abnormal symptoms appear, it is necessary to go to hospital for systematic diagnosis and treatment in time.
