Stage IIIB cervical cancer; drawing shows cancer in the cervix, the vagina, and  the pelvic wall, blocking the ureter on the right. The uterus and kidneys are also shown.
Stage IIIB cervical cancer. Cancer has spread to the pelvic wall; and/or the tumor has become large enough to block the ureters (the tubes that connect the kidneys to the bladder). The drawing shows the ureter on the right blocked by the cancer. This blockage can cause the kidney to enlarge or stop working.
