Staging Ovarian CancerStage ovarian cancer describes the extent to which the tumor has spread outside the ovary to nearby tissues and other parts of the body. Staging is done during the surgical biopsy, and generally requires removing lymph nodes, samples of tissue from the diaphragm and other abdominal organs, and fluid from the abdomen. When diagnosed early (Stage I), a woman has a 95% chance of being cured. However, only 25% of ovarian cancer cases are diagnosed in early stages. Ovarian cancer staging is as follows: Stage I: The cancer is limited to the ovary or ovaries. Stage IA: The tumor is limited to the inside of one ovary Stage IB: The tumor is limited to the inside of both ovaries Stage IC: The tumor is limited to one or both ovaries. In addition, it appears on the surface of the ovary, a fluid-filled capsule has burst, or cancer cells are found in abdominal fluid. Stage II: The cancer is in one or both ovaries and has spread to other parts of the pelvis. Stage IIA: The tumor has spread to the uterus, fallopian tubes or both Stage IIB: The tumor has spread to the bladder, rectum or colon Stage IIC: The tumor has spread to any of the above. Also, it appears on the surface of the ovary, a fluid-filled capsule has burst, or cancer cells are found in abdominal fluid. Stage III: The cancer is in one or both ovaries and has spread to nearby lymph nodes or other abdominal organs, not including the liver. Stage IIIA: The tumor has spread to the lining of the abdomen but cannot be seen. The cancer has not spread to the lymph nodes. Stage IIIB: The cancer has spread into the abdomen and is visible (less than 2 centimeters, about 3/4 of an inch, in size). The cancer has not spread to the lymph nodes. Stage IIIC: The cancer has spread into the abdomen and the deposits measure larger than 2 centimeters. The cancer has spread to the lymph nodes. Stage IV: The cancer has spread to the lung, liver or other distant organs. Recurrent ovarian cancer: The cancer has come back after it has been treated. It may appear in other parts of the body, but is still considered ovarian cancer.
