Stage I: During ovarian cancer stage 1, the cancer is confined to the ovaries and hasn’t spread to the abdomen, pelvis or lymph nodes, or to the distant sites.
Stage II: The cancer at this stage is present in one or both ovaries and has spread to the pelvic region, such as the fallopian tubes or uterus.
Stage III: The cancer at this stage is present in one or both the ovaries. Also, it has spread beyond the pelvis to the lining of the abdomen or to the lymph nodes.
Stage IV: During this advanced stage, the cancer has metastasized to the distant sites, such as the inside of the spleen, liver, lungs or other organs outside the abdomen and pelvic region.
