The FIGO staging: Is clinical and applicable world-wide, so fancy tests (ct, mri, pet) excluded. I confined to cx, ii extends to vagina or up to body, iii further down the vagina or outward to parametrium, IV invading adjacent (bladder rectum) or metastasis beyond pelvic nodes.

See below: After a diagnosis of cervical cancer, a number of testing modalities are used to assess as to how far the cancer has spread. See this site for details. http://www.cancer.gov/cancertopics/pdq/treatment/cervical/patient/page2.
