Smoking and Mesothelioma

Mesothelioma is a rare form of cancer that occurs in the mesothelium, a thin layer of tissue that covers almost all of the internal organs. Pleural mesothelioma affects the pleural lining of the lungs. Pleural mesothelioma accounts for over 70% of all mesothelioma cases. Peritoneal mesothelioma affects the tissues of the abdomen and pericardial mesothelioma affects the pericardium, or lining of the heart. Many factors contribute to the increased risk of mesothelioma such as inherited traits, environment, general health status and lifestyle choices. Exposure to asbestos is the primary risk factor for contracting mesothelioma. Asbestos fibers are found in insulation, cement, brakes, shingles, flooring and many other products. Smoking increases the risk of developing mesothelioma in workers exposed to asbestos. Symptoms and Signs The symptoms and warning signs differ depending on the organs involved. Pleural mesothelioma symptoms may include:
• Shortness of breath
• Pleurisy (painful breathing)
• Painful cough
• Chest pain under ribcage
• Lumps under skin of chest
• Unexplained weight loss
• Dry cough
The symptoms of peritoneal mesothelioma may include:
• Abdominal pain
• Abdominal swelling
• Constipation and/or diarrhea
• Lump in abdomen
• Unexplained weight loss
Pericardial mesothelioma symptoms may present with difficulty breathing and/or chest pains, while mesothelioma of the tunica vaginalis may reveal a mass on the testicle. Various diagnostic tests are required to confirm the diagnosis of mesothelioma. Treatment depends on the extent of the disease. Mesothelioma may lead to death. People afflicted with mesothelioma die from related complications such as lung failure, heart problems, stroke and other causes.
