The tumor is found in one or both ovaries and has spread into other areas of the pelvis. Stage II is divided into stage IIA, IIB, and IIC. In stage IIA, the tumor has spread to the uterus and/or the fallopian tubes (the long, slender tubes through which eggs pass from the ovaries to the uterus). In stage IIB, the tumor has spread to other tissue within the pelvis. In stage IIC, (1) the tumor has spread to the uterus and/or the fallopian tubes and/or other tissue within the pelvis; and (2) tumor cells are found in the fluid of the peritoneal cavity (the body cavity that contains most of the organs in the abdomen).
