Several mechanisms can explain why cancer might cause bloating:
Tumor Growth: A tumor in the abdomen can physically obstruct the intestines, leading to a buildup of gas and fluids. Ascites: This is a condition where fluid accumulates in the abdominal cavity, often due to cancers like ovarian or liver cancer. Peritoneal Carcinomatosis: This occurs when cancer spreads to the lining of the abdominal cavity, causing irritation and fluid buildup. Metabolic Changes: Cancer can alter metabolism, leading to changes that may cause bloating.
