Recurrence of cervical cancer: As the surrounding tissues where the tumor is located are prone to have tumor cells remaining after surgery, and at the same time common metastatic foci, such as lungs and bones, are prone to have corresponding symptoms, therefore, the symptoms of recurrence of cervical cancer after surgery commonly include abdominal pain, leucorrhoea abnormality, and menstrual abnormality for those who retain the uterus. Since the cervix is adjacent to the urinary system, the site of tumor recurrence can be located in the urinary system, thus symptoms such as hematuria and frequent urination can appear. The first symptom of tumor recurrence can be generalized fever, abnormal defecation and so on. 3.
