How common is abdominal swelling in liver cancer?

Liver cancer may affect blood flow through the liver and contribute to a build-up of fluid in the abdomen, known as ascites. The abdomen may feel full, tight or heavy, and clothes may become uncomfortable. Swelling can also occur with liver disease, heart problems, kidney problems, digestive conditions or other causes.

A clinician may ask when the swelling began, whether it is changing, and whether there is pain, breathlessness, nausea, yellowing of the skin or legs that are also swollen. Examination and tests help identify the cause; the symptom alone cannot distinguish liver cancer from other conditions.

Arrange medical assessment for new, persistent or increasing abdominal swelling, particularly if you have known liver disease or other liver symptoms. Note changes in size, discomfort, appetite, weight, urine, bowel movements and breathing, and bring a list of medicines and supplements.

Do not start water tablets, restrict fluids or make major diet changes without advice. If ascites is suspected, the team may discuss tests and treatments based on the cause and your overall health.

Seek urgent medical care for rapidly increasing swelling, severe or new abdominal pain, fever, repeated vomiting, confusion, fainting or difficulty breathing. Emergency help is needed for severe breathlessness, collapse or sudden confusion. These warning signs can reflect complications that need prompt assessment.

Ask what may be causing the swelling, whether fluid is present and which tests are needed. Ask how to monitor changes at home, which foods or medicines to avoid, and which symptoms should lead to a same-day call.
