The symptoms of mesothelioma are often confused with many other conditions, and because the onset of symptoms can occur many years after exposure (sometimes 20 years, or even 30 to 50 years), there can be a delay in diagnosis – or even seeking medical opinions.

The symptoms of the three types of mesothelioma will be covered here, as well as common symptoms seen in all types of mesothelioma.

The information contained here should not constitute a diagnosis. Only a doctor can determine whether symptoms are mesothelioma or something less serious such as pneumonia, flu or bronchitis.

Unfortunately, by the time the symptoms present and the patient has seen a doctor, the cancer is usually well advanced. The good news is mesothelioma is not common, and it is actually thought to be decreasing in occurrence, particularly in the United States of America.

Common Symptoms of Mesothelioma.

Pleural effusion is the most common symptom of mesothelioma. This is where fluid gathers in the pleural space, or the lining of the chest wall, diaphragm and lungs. Pleural effusion causes shortness of breath as the patient cannot draw air as easily due to decreased space for the lungs to inflate. Pain can also present, as well as a dry cough. A husky voice and difficulty swallowing go along with the effusion and resulting cough.

Difficulty breathing can lead to lack of sleep, and it is usually the cough, shortness of breath and poor sleep that sees patients present to their doctor. Loss of appetite and weight loss are also seen.

Pleural Mesothelioma (cancer in the lining of the lungs) results in symptoms relating to the chest and lung area: pain in the chest area, coughing and wheezing, shortness of breath, pleural effusion and trouble speaking/husky voice.

Peritoneal Mesothelioma (cancer in the lining of the abdomen) can present in the following ways: abdominal pain, abdominal swelling, obstruction of the bowel, vomiting, nausea, fever, anaemia and weakness. Blood clotting is a less common symptom, but just as serious.

Pericardial Mesothelioma (cancer of the lining of the heart) often shows in the following ways: pain in the chest area, shortness of breath, coughing that won’t go away, unusual amounts of tiredness after the smallest amount of exercise and heart palpitations.

Again, this information should not replace an accurate and informed diagnosis by a doctor.
