2) Abdominal swelling:
Mesothelioma in the abdominal cavity can sometimes cause prominent swelling of the stomach, and this swollen area may be painful to the touch. This particular symptom comes from an abnormal retention of fluid in your abdomen. When fluid is retained, it also inhibits the function of the organ. This is also called as peritoneal effusion. This means that there is a large amount if fluid within the peritoneal cavity of the abdomen. Although this effusion is not a condition, it is often a symptom of a greater disease. For patients with mesothelioma, abdominal swelling is often present and usually affects the pleura, peritoneum and pericardium. Effusion is most common with peritoneal mesothelioma; this is when fluid from the peritoneum exceeds the normal amount by a couple of teaspoons. Abdominal pain occurs when there is rapid fluid retention in the peritoneum. When this happens, there may present of symptoms like bowel obstruction, abdominal swelling and even weight loss. As the pressure increases in the stomach, pain is often felt which often results in difficulty in eating. Not only that, the swelling of the abdomen may also put pressure on the intestines as well as the bladder. When this happens, difficulty in urinating or moving bowel occurs. The patient may also experience fatigue, rapid heartbeat, chest or abdominal pain and shortness of breath.
