MESOTHELIOMA SYMPTOMS

Mesothelioma is often difficult to diagnose, primarily due to the non-specific nature of patient symptoms. The onset of mesothelioma symptoms is usually very slow, and may not appear until 30 to 50 years after exposure to asbestos. The following symptoms are frequently reported by those with mesothelioma, but are also associated with other medical conditions.

The following symptomatic responses MAY BE caused by mesothelioma, or by other less serious medical problems. Early symptoms of mesothelioma are often similar to pneumonia. This information is provided for your information only, and should NOT take the place of a full medical diagnosis. If you are experiencing any of the below symptoms, consult your doctor right away.

Symptoms of Pleural Mesothelioma

* Pleural Effusions
One of the most common symptoms of mesothelioma is a pleural effusion, or an accumulation of fluid between the lining of the lung and the chest cavity. As the volume of fluid increases, shortness of breath, known as "dyspnea", and sometimes pain may occur.

* Shortness of Breath
Difficulty breathing (dyspnea) can be caused by a buildup of fluid in the pleural area of the lungs, and/or the presence of a tumor(s) in the pleural lining. Both conditions can restrict the proper functioning of the lungs, resulting in shortness of breath.

* Chest / Back Pain
A buildup of fluid in the pleural lining of the lungs can create a feeling of fullness and pressure, causing areas of localized pain in the chest cavity and sometimes in the lower back area. Chest pain occurs more often on the right side of the body, as mesothelioma affects the right lung 60% of the time. Only 5% of patients have mesothelioma in both lungs.

* Chronic Hoarseness / Difficulty Swallowing / Coughing up Blood
Chronic hoarseness, difficulty swallowing (dysphagia), and/or the coughing up of blood (hemoptysis) are symptoms that are exhibited in less than 1% of undiagnosed mesothelioma sufferers.

* Swelling of the Face and Arms
The swelling of the face or neck areas can indicate a spreading of the cancer beyond the mesothelium.

* Other reported symptoms include fever, muscle weakness and sensory loss, and nausea.
