Cervical cancer can be divided into the following stages according to disease development: 1. precancerous stage: it can be blocked by precancerous screening and will not develop into cervical cancer; 2. stage I: lesions are confined to the cervix; 3. stage II: lesions invade both sides of the uterus or pelvic tissues; 4. stage III: lesions invade the pelvic wall; 5. stage IV: distant metastases, such as liver metastases and lung metastases, etc., and the prognosis is poor. Early cervical cancer can be detected by women’s screening. It is recommended that women should take regular medical checkups or two cancer screenings during their childbearing years to reduce the risk of cancer.
