How do symptoms differ in early-stage and late-stage ovarian cancer?

One study reported that when comparing various symptoms found in early and late stage ovarian cancers, women with early stage disease reported more nausea than those with advanced. Note that there is an overlap between early and late stage disease with regard to the types of symptoms experienced. Symptoms that are more associated with late instead of early stage disease include abdominal distension, swelling, ascites (fluid in the abdomen causing abdominal distension), diarrhea, constipation and abdominal pain.
