Cervical cancer is a relatively common gynecological malignancy, ranking 2nd in incidence among all female malignancies, second only to breast cancer, but with the widespread use of cervical cancer vaccine, the incidence and mortality rates are relatively stable and have decreased. Early clinical symptoms of cervical cancer are not very obvious, some patients may have symptoms such as contact vaginal bleeding, abnormal leucorrhea and vaginal discharge, which can be confirmed by colposcopic biopsy.
