Cervical cancer is the most common malignant tumor of the female genitalia, with the age of onset mostly between 40-55 years old, followed by 60-69 years old. The occurrence of cervical cancer often goes through a long process of chronic cervicitis (especially cervical erosion), cervical squamous epithelial atypical hyperplasia, carcinoma in situ to invasive carcinoma, which may last for years, decades or decades. Clinical manifestations of cervical cancer: irregular vaginal bleeding and fluid discharge: early manifestation is a small amount of bleeding after sexual intercourse or gynecological examination, and later may be a small amount of irregular bleeding between menstruation or after menopause. In late stage, bleeding increases and even fatal heavy bleeding occurs. Increased leucorrhea, often plasma, pus or rice soup-like blood foul-smelling leucorrhea. Pain is a late symptom, manifested as persistent lumbosacral or sciatica. Gynecological examination can see cervical erosion, ulceration or cauliflower-like neoplasm. Diagnosis of cervical cancer: 1. Appearance of the aforementioned symptoms or signs. 2.Cancer cells are seen in cervical scraping cytology. 3.Colposcopy reveals heterogeneous epithelial area and biopsy reveals cancerous tissue. 4.Cancerous tissue was found in biopsy taken from the cervix or cervical canal. 5.Conical hysterectomy was performed for those with positive cytology and negative biopsy, and cancerous tissues were found in successive sections of the excised specimen.
