Cervical cancer staging criteria

Cervical cancer can be divided into stages I, II, III and IV according to the specific location of the tumor. Stage I cervical cancer refers to the tumor confined to the cervix, without metastasis elsewhere, only limited to the cervix, called stage I cervical cancer. Stage II cervical cancer is cancer beyond the uterus, but did not reach the pelvic wall, or did not reach 1/3 of the vagina, this is called stage II cervical cancer. Stage III cervical cancer is when the tumor has spread to the pelvic wall and there is no clear gap between the tumor and the pelvic wall at the time of digital rectal examination. The tumor will involve 1/3 of the vagina. Cases of hydronephrosis or renal function caused by the tumor are considered to be stage III. Stage IV cervical cancer extends beyond the true pelvis, or invades the bladder, or invades the rectal mucosa, and has distant metastasis.
