Symptoms in Other Areas
In addition to the lungs, many other body parts, such as testicles, heart, abdominal cavity, or chest cavity, can be affected. Depending on the affected areas, exact symptoms can vary. When the condition affects the abdomen and stomach, you can have diarrhea, vomiting, nausea, abdominal pain, unexpected weight loss, loss of appetite, or lack of energy. Mesothelioma in the heart can trigger chest pain, difficulty breathing, low blood pressure, or irregular heartbeat. [2]
