Stage 3 ovarian cancer means that the cancer has spread beyond the ovaries to other areas within the abdomen or pelvis, but it has not yet spread to distant parts of the body like the liver or lungs.

According to the American Cancer Society and NCCN guidelines, ovarian cancer staging is based on how far the cancer has spread at the time of diagnosis. In stage 3, the cancer has spread within the abdominal cavity, often involving the lining of the abdomen (peritoneum) or lymph nodes in the pelvis or abdomen. This stage is divided into subcategories (3A, 3B, 3C) based on the extent and location of spread:

Stage 3A: Cancer has spread to the lining of the abdomen (peritoneum) or lymph nodes in the pelvis, but the tumors are small.
Stage 3B: Tumors are larger than in 3A and may be visible in the abdomen or pelvis.
Stage 3C: Cancer has spread more extensively within the abdomen, with larger tumors or spread to lymph nodes in the abdomen.

The reason for this staging is to help determine the best treatment options and to understand the prognosis. Treatment often involves a combination of surgery to remove as much tumor as possible and chemotherapy to target remaining cancer cells.

It's important to discuss your specific diagnosis with your healthcare team, as they can provide details tailored to your situation. Always consult with your oncologist for personalized information.
