The survival time of radiotherapy for stage IV cervical cancer is related to the individual’s physical condition as well as the treatment effect, and the general probability of five-year survival is not high. Cervical cancer is a relatively common type of cancer. Stage IV cervical cancer means that the cancer cells have spread widely, which may lead to invasion of bladder mucosa and rectal mucosa, and even cause distal metastasis, such as supraclavicular lymph node metastasis and lung metastasis, etc. In this case, the five-year survival time after receiving chemotherapy is often limited. Because of the wide spread of cancer cells, surgical treatment is meaningless for stage IV cervical cancer, and only chemotherapy or radiotherapy can be accepted. Generally, localized lesions can use radiotherapy; distal metastatic lesions can use chemotherapy or both treatments of radiotherapy and chemotherapy. Therefore, cervical cancer is very dangerous, and it is suggested that once diagnosed, it is necessary for patients to have active and early treatment.
