Cervical cancer is a common malignant tumor that threatens women’s health. It can be diagnosed by HPV test, cervical smear, colposcopic cervical biopsy and pathological tissue section. There is no clear time from detection to death because the prognosis of cervical cancer is closely related to clinical stage and pathological type, which needs to be judged according to specific conditions.1. Early stage cervical cancer: cancerous lesions are confined to the cervix, often appearing as increased vaginal discharge and irregular vaginal bleeding, generally without other symptoms, including precancerous lesions and carcinoma in situ, and the main treatment is surgery, and after treatment, the five-year survival rate of early stage cervical cancer can reach 70%-80 The five-year survival rate of early cervical cancer can reach 70%-80% after treatment, and the five-year survival rate of in situ cancer can reach over 90%. Therefore, early diagnosis is very important for patients. 2. Middle stage cervical cancer: Patients with middle stage cervical cancer will have symptoms such as pain, infection and fever in addition to vaginal bleeding and vaginal discharge because the lesion has already invaded. With radical radiotherapy, the treatment effect is still good and the five-year survival rate can reach about 60%; 3. Advanced cervical cancer: multiple metastases to the pelvic or vaginal wall and other organs, large amount of purulent or rice-soup-like foul-smelling leukorrhea may appear, and severe and continuous lumbosacral or lower limb pain may occur, with relatively poor prognosis. Early prevention of cervical cancer is important, and good early screening can effectively interrupt the occurrence of cervical cancer. Therefore, women should have regular gynecological examination for early detection and early treatment of cervical precancerous lesions.
