Cervical cancer staging is the assessment of cervical cancer to decide how far the disease has progressed. This is important for determining disease prognosis and treatment. Cancer staging generally runs from stage 0, which is pre-cancerous or non-invasive, to stage IV, in which the cancer has spread throughout a significant part of the body.
Cervical cancer is staged by the International Federation of Gynecology and Obstetrics staging system. Prior to the 2018 update, FIGO staging of cervical cancer allowed only the following diagnostic tests to be used in determining the stage: palpation , inspection, colposcopy, endocervical curettage, hysteroscopy, cystoscopy, proctoscopy, intravenous urography, and X-ray examination of the lungs and skeleton, and cervical conization. But with the 2018 update of FIGO staging of cervical cancer, imaging and pathology were added as allowable methods to assess disease stage.
