A 62-year-old woman presents with a 4-month history of increasing abdominal distension, bloating, and a sensation of early fullness after eating. She has also noticed a gradual increase in her waist circumference and reports feeling more fatigued than usual. Her medical history includes well-controlled type 2 diabetes mellitus and hypercholesterolaemia, managed with metformin and atorvastatin respectively. She is post-menopausal, having completed menopause 10 years ago. On physical examination, her vital signs are stable: blood pressure 128/78 mmHg, heart rate 68 bpm, respiratory rate 14/min, and temperature 36.6°C. Abdominal examination reveals moderate distension and a firm, irregular mass is palpable extending from the pelvis into the lower abdomen. Bowel sounds are present and normal.
