11 Common Symptoms Linked To Liver Cancer

5. Abdominal Swelling

Abdominal swelling is a common symptom seen in individuals affected by liver cancer. General abdominal swelling occurs due to the enlargement of the liver by the rapid growth of the cancerous tumor. Additionally, both the cancerous tumor growth and cirrhosis from liver tissue damage can cause the buildup of pressure in the liver. Increased pressure in the liver does not allow adequate amounts of blood to pass through the veins, resulting in a backup of blood in the veins. Naturally occurring mechanisms are in place that causes fluid to leech from the veins into neighboring tissues when there is an accumulation or pooling of blood. The fluid may leak into the inner peritoneum that contains the liver and other organs, or it can leak into the space between the inner and outer peritoneum layers. The peritoneum is responsible for producing a trivial amount of fluid between its layers to assist with lubrication and to protect the organs. Cancerous cells can cause the lining to become inflamed and produce excess fluid as a result. Liver cancer can obstruct the lymph vessels responsible for draining excess fluid, also allowing it to build up in the abdomen.

6. Persistent Nausea and Vomiting

Chronic nausea and vomiting can be more than just signs of an upset stomach—they can be subtle red flags for liver cancer. As tumors grow and liver function declines, the buildup of toxins in the blood can trigger digestive distress. The liver normally filters out harmful substances, but when it’s compromised, these toxins linger in the bloodstream and affect multiple systems, including the stomach and brain. Additionally, reduced bile production disrupts digestion, leading to nausea after meals or even on an empty stomach. Vomiting may become more frequent as the disease progresses, especially in tandem with appetite loss or abdominal swelling. If these symptoms are persistent and unexplained, they warrant a closer look—especially if other signs of liver dysfunction are present.
