Cervical Cancer Stages
Staging is a standard way of categorizing cancers that is used to determine prognosis and treatment. The staging for cervical cancer is as follows:
- Stage I: The cancer is still limited to the cervix
- IA A microscopic cancer is limited to the cervix and only seen on biopsy.
- IB Cancer is visible to the naked eye during an exam.
- IB1: The cancer is smaller than 4 cm.
- IB2 : The cancer measures larger than 4 cm.
- Stage II: Cancer has spread beyond the cervix to the side tissue near the cervix or into the top of the vagina.
- Stage III: Cancer has spread beyond the cervix to the pelvic side wall or has caused swelling or blockage of urine flowing into the bladder or involves the lower vagina.
- Stage IV: Cancer has spread beyond the cervix or any of the above areas and has involved the bladder, rectum or any distant organ such as the lung or liver.
