Ovarian cancer survival is stage-dependent: Stage I patients have 90% 5-year survival versus 15% for stage IV. Over 70% of patients worldwide are diagnosed at advanced stages. Ovarian cancer presents with non-specific symptoms (abdominal bloating, early satiety, discomfort/pain, bowel/urinary changes). Current National Institute for Health and Care Excellence guidelines recommend that symptomatic women presenting to primary care are tested with cancer antigen 125 and ultrasound, then referred to secondary care for further triage if these tests are abnormal.
