Mesothelioma is a rare form of cancer that is usually found in those previously exposed to asbestos. Cancerous cells form in the mesothelium, which is a protective lining that covers most of the body's internal organs. These cells typically form in the lining of the lungs, abdomen, or the sac that encircles the heart.
The average life span of a person diagnosed with the disease is about 4 to 24 months from the finding. About 3,000 people in the U.S. die of mesothelioma every year. People at risk are those who have been previously exposed to asbestos dust, including former steel workers, auto mechanics, mineworkers, and military workers, among many others. Their family members may also be at risk, as the asbestos dust from clothing can travel through the air.
Mesothelioma has an extremely long latency period, which means that symptoms of the disease may not emerge until 30 to 50 years after the initial exposure to asbestos. Pleural mesothelioma, which is the most common type and affects the area around the lungs, may cause shortness of breath, chest pains, and a persistent cough, which may lead to coughing up blood. These symptoms are caused by the build up of fluid between the lining of the lung and the chest cavity. The disease may start in the chest area and spread to other areas of the body. Other symptoms of pleural mesothelioma include weight loss, severe breathing trouble, fever, difficulty swallowing, and swelling of the face and neck areas. It should be noted that some people with the disease do not experience any serious symptoms at all.
Peritoneal mesothelioma is rarer than pleural mesothelioma, and affects the abdominal area. Symptoms of peritoneal mesothelioma include abdominal swelling and pain due to the build up of fluid in the abdominal cavity, nausea, loss of appetite, and vomiting. Breathing complications and chest pains may also be present, as well as bowel obstruction, anaemia, fever, and blood clotting.
The rarest form of the disease is pericardial mesothelioma, which first forms in the area surrounding the heart. Tumors grow in the tissues around the heart and spread from there. Chest pain, shortness of breath, constant coughing, and shivering may be symptoms of this form of mesothelioma.
