Cervical Cancer Stages
In the level cervical cancer can distinguish the following phases or stages depending on tumor size or the area that reaches:
Stage 0
In stage 0 (called carcinoma in situ or preinvasive carcinoma) cells are found in the innermost lining of the cervix, is very superficial, limited to the mucosal cells. These abnormal cells may become cancer and spread into nearby normal tissue.
Stage I
In stage I, cancer has formed and is found only in the cervix. Stage I is divided into stages IA and IB, according to the amount of cancer that is found.
Stage IA: it detects a very small amount of cancer in tissues of the cervix that can only be seen under a microscope. Stage IA is divided into two more stages according to tumor size.
Stage IB: In stage IB, cancer can only be seen with a microscope and is more than 5 millimeters deep or is larger than 7 mm wide, or it can be seen without a microscope. The cancer can be seen without a microscope is divided into two stages according to tumor size.
Stage II
In stage II, cancer has spread beyond the cervix but not to the pelvic wall (the tissues that line the part of the body between the hips) or to the lower third of the vagina and / or the lateral ligaments (parametrium). Stage II is divided into two stages according to how far the cancer has spread:
Stage IIA: Cancer has spread beyond the cervix to the upper two thirds of the vagina, but not to tissues around the uterus.
Stage IIB: Cancer has spread beyond the cervix to the upper two thirds of the vagina and the tissues surrounding the uterus.
Stage III
In stage III, cancer has spread to the lower third of the vagina, affects nearby lymph nodes or tissues lso side reaches the cervix to reach the pelvic wall or may have caused the kidney to stop working. Stage III is divided into stages IIIA and IIIB, based on how far the cancer has spread.
Stage IIIA: Cancer has spread to the lower third of the vagina, but not to the pelvic wall.
Stage IIIB: Cancer has spread to the pelvic wall or the tumor is large enough to block the ureters (tubes that connect the kidneys to the bladder). This blockage can cause the kidneys to enlarge or stop working. Cancer cells may also have spread to lymph nodes in the pelvis.
Stage IV
In stage IV, cancer has spread to the bladder, rectum or other body parts, with lymph. Stage IV is divided into stages IVA and IVB, depending on where the cancer.
Stage IVA: Cancer has spread to the bladder or rectal wall and may have spread to lymph nodes in the pelvis.
Stage IVB: Cancer has spread beyond the pelvis and pelvic lymph nodes to other places in the body including the abdomen, liver, intestinal tract or lungs.
