The following stages are used in the classification of cervical cancer:
Stage O
Stage O or carcinoma in situ. Carcinoma in situ is very early cancer. Abnormal cells are found only in the first layer of cells lining the cervix, and do not invade deeper tissues of the cervix.
Stage I
Cancer involves the cervix but has not spread to the surroundings.
Ia: a very small amount of cancer, visible only by microscope, is already in the deeper tissue of the cervix.
Ib: a larger amount of cancer found in this tissue.
Stage II
The cancer has spread to nearby areas, but still in the pelvic area.
II-a: the cancer has spread beyond the cervix to the upper two thirds of the vagina.
II-b: The cancer has spread to tissue around the cervix.
Stage III
The cancer has spread throughout the pelvic area. May have spread to the bottom of the vagina, or infiltrate the ureters (the tubes that connect the kidneys to the bladder).
Stage IV
The cancer has spread to other parts of the body.
IV-a: Spread to the bladder or rectum (organs close to the cervix)
IV-b: Spread to distant organs like the lungs.
Appellant
Recurrent disease (relapse) means the cancer has returned after having been treated. It can occur in the cervix itself or appear in another location.
