• Stage 1: The tumor has invaded the cervix beneath the top layer of cells. Cancer cells are found only in the cervix.

• Stage 2: The tumor extends to the upper part of the vagina. It may extend beyond the cervix into nearby tissues toward the pelvic wall (the lining of the part of the body between the hips). The tumor does not invade the lower third of the vagina or the pelvic wall.

• Stage 3: The tumor extends to the lower part of the vagina. It may also have invaded the pelvic wall. If the tumor blocks the flow of urine, one or both kidneys may not be working well.

• Stage 4: The tumor invades the bladder or rectum. Or the cancer has spread to other parts of the body.

• Recurrent cancer: The cancer was treated, but has returned after a period of time during which it could not be detected. The cancer may show up again in the cervix or in other parts of the body.
