Types of Mesothelioma

Author: Cancer Care

A lot of mesothelioma related diseases exist. Mesothelioma can be classified by their location. Below shows the common types of mesothelioma.   

   Pleural — 75% of all mesothelioma cases   

  Peritoneal — 10%–20%  

  Pericardial — 5%     

     Lung Cancer Mesothelioma   Lung cancer is the leading cause of death in mesothelioma illnesses. When these asbestos fibers are inhaled or ingested, they may become trapped in the lungs or the digestive tract permanently, causing serious illness or disease such as lung cancer mesothelioma. Lung cancer is difficult to diagnose early and it also spreads at a rapid rate, and is rarely cured. Lung cancer mesothelioma typically occurs at a younger age than other lung cancers. It equally has a smaller latency time than other mesothelioam related cases. If you’ve worked in places that exposes you to asbestos, and you start developing Change in breathing patterns, Shortness of breath Persistent chest pains, Coughing, Hoarseness, Anemia, then you need to do two smart things: Visit your doctor See a mesothelioma lawyer or mesothelioma attorney.  

Malignant pleural mesothelioma  Malignant pleural mesothelioma is an asbestos-related cancer that affects the lining of the chest cavity. One of the main problems in diagnosing malignant pleural mesothelioma is that the disease has a very slow onset. Additionally, many individuals with malignant pleural mesothelioma do not immediately seek treatment because of the generalized nature of their symptoms. Early signs of malignant pleural mesothelioma include persistent pain in the chest, shortness of breath, weight loss and fever. Patients diagnosed with pleural mesothelioma have cancerous growths in the tissues and lining surrounding their lungs. Men between the ages of 50 and 70 are more commonly diagnosed with pleural mesothelioma. 

ymptoms of Pleural Mesothelioma   Pleural mesothelioma is a deadly and devastating disease with no known cure. Initial symptoms of pleural mesothelioma are often vague:    

  shortness of breath   

  chest pains   

  coughing      

  Peritoneal mesothelioma  

Peritoneal mesothelioma is a relatively rare form of malignant mesothelioma, making up slightly less than 30% of diagnosed mesothelioma cases. This type of mesothelioma affects the cells of the abdominal lining, also known as the peritoneum, which supports and protects organs in the abdomen. It is widely believed that asbestos fibers that are inhaled are transported to the peritoneum via the lymphatic system.  Once in the peritoneum, asbestos fibers cause changes in peritoneal cells that cause them to divide without restraint, causing the peritoneal layers to thicken. The growth of cancer cells puts pressure on internal organs, and this pressure is increased by fluid that builds up in the area as a result of cancer growth. 

    Pericardial mesothelioma  

Pericardial mesothelioma is the least common form of a mesothelioma. Only around 5% of mesothelioma cases are pericardial. This type of mesothelioma affects the pericardium, which is a membranous lining that surrounds the heart, providing both support and protection to the organ. Once asbestos fibers are lodged in the membranes surrounding the heart, they cannot be eliminated by the body. These fibers then begin to cause changes in the pericardial membrane. While the exact nature of these changes is not completely understood, it is known that these changes eventually lead to uncontrolled growth of cells in the pericardial layers, causing malignant mesothelioma tumors to form.  Symptoms of Pericardial Mesothelioma   The rarity of pericardial mesothelioma has made it difficult for specialists to determine a specific set of common symptoms. The following symptoms often indicate a cardiac condition, but further tests are required to confirm a diagnosis of pericardial mesothelioma.s

Important Steps to Prevent Mesothelioma.

by JVC ajeet

Mesothelioma is a rare cancer that attacks the body's mesothelial cells around the organs. The mesothelium provides a protective membranous lining for the internal organs and allows moving organs (i.e. the heart and the lungs) to glide easily against adjacent structures. The names of the three regions of mesothelial cells that provide protective coating are 1) pleura, the sac which surrounds the lungs; 2) peritoneum, the lining which protects the abdominal cavity; and 3) pericardium, the sac which surrounds the heart. Three different types of mesothelioma cancer attack these three different regions.
Pleural mesothelioma: A type of lung cancer which attacks the pleura surrounding the lungs, this is the most common type of mesothelioma, affecting approximately two-thirds of all mesothelioma patients. Symptoms include horseness, fever, blood in sputum, swollen arms and face, coughing, loss of weight, difficulty breathing, chest pain, weak muscles, and reduced tactile sensitivity.

Peritoneal mesothelioma: A cancer of the abdomen which attacks the peritoneum lining the abdominal cavity. This affects approximately one-third of all mesothelioma patients. Symptoms include abdominal bloating, impaired bowl function, fever, swollen feet, and nausea.Pericardial mesothelioma: This form of mesothelioma which attacks the pericardium surrounding the heart is extremely rare. Symptoms include chest pain, dyspnea, cough, and palpitations.

Mesothelioma has been linked to asbestos exposure. Asbestos is a type of building material used in thermal insulation products and ceiling tiles. In the United States, asbestos usage peaked during the 1950s - 1970s. During the late 1960s, concerns over the health consequences of asbestos exposure began to arise, thereby decreasing the amount of asbestos manufactured in next two decades. By the 1980s, a new industry of asbestos abatement began to flourish. But according to the United States Environmental Protection Agency (EPA), as many as 733,000 schools and public buildings still contain asbestos.

Small asbestos fibers that enter the air do not evaporate and can remain suspended in the air for a long time. These fibers, when breathed into the body, are toxic. There are three types of asbestos exposure. Occupational asbestos exposure: People working in factories that manufacure asbestos are likely to have a high exposure to asbestos and are most at risk of developing asbestosis or mesothelioma.

Paraoccupational asbestos exposure: Family members of workers exposed to asbestos in the workplace are susceptible to exposure from asbestos dust brought home by the worker on his clothes or skin. Neighborhood asbestos exposure: Those who live in the vicinity of an asbestos manufacturing plant are also at risk.

Mesothelioma is still a relatively rare form of cancer. There are an estimated 2,000 - 3,000 new cases per year in the United States. Approximately 7-13 per one million male patients with a history of asbestos exposure contract mesothelioma. Diagnosis usually occurs 20-40 years after initial exposure to asbestos.
