Staging of cervical cancer can either be based on the TNM or FIGO system.

Revised FIGO staging of cervical carcinoma 2009 ⁸

stage 0: cervical intraepithelial neoplasia (HSIL or CIN III)
stage I: confined to cervix
- stage Ia: invasive carcinoma only diagnosed by microscopy.
  - Ia1: stromal invasion <3 mm in depth and <7 mm in extension (microinvasive)
  - Ia2: stromal invasion >3 mm depth and not >5 mm and extension <7 mm
- stage Ib: clinically visible lesions limited to the cervix or pre-clinical cancers >stage 1a
  - Ib1: clinically visible tumour <4 cm in greatest dimension
  - Ib2: clinically visible tumour >4 cm in greatest dimension
stage II: beyond cervix though not to the pelvic sidewall or lower third of the vagina.
- stage IIa: involves upper 2/3^rd of vagina without parametrial invasion
  - stage IIa1: clinically visible tumour <4 cm in greatest dimension
  - stage IIa2: clinically visible tumour >4 cm in greatest dimension
- stage IIb: with parametrial invasion
stage III
- stage IIIa: tumour involves the lower third of the vagina with no extension to pelvic sidewall
- stage IIIb: extension to pelvic side wall or causing obstructive uropathy, MR imaging findings that are suggestive of pelvic sidewall involvement include tumour within 3 mm of or abutment of the internal obturator, levator ani, and pyriform muscles and the iliac vessel ⁶
stage IV: extension beyond true pelvis or biopsy proven to involve the mucosa of the bladder or the rectum
- stage IVa: extension beyond true pelvis or rectal/bladder invasion
- stage IVb: distant organ spread
