Cancer has spread beyond the abdomen to other parts of the body. Stage IV is divided into stages IVA and IVB. In stage IVA, cancer cells are found in extra fluid that builds up around the lungs. In stage IVB, cancer has spread to organs and tissues outside the abdomen, including lymph nodes in the groin.
