How to stage cervical cancer mainly depends on the size of the lesion, the extent of tumor invasion, and whether there is metastasis. Generally speaking, if the lesion is less than three centimeters and there is no vaginal invasion, it is an early condition. Secondly, the invasion of vaginal and parauterine tissues by the focus is mostly in the middle stage. Uterine invasion and distant metastasis are late cases. Cervical cancer is mainly diagnosed by biopsy and pathology. In the early stage of cervical cancer, surgery is the first choice, followed by comprehensive radiotherapy and chemotherapy for the treatment of advanced cervical cancer. Early cervical cancer can be cured by surgical treatment, and the survival period of intermediate and advanced cervical cancer can reach about three or five years by treatment.
