Mesothelioma is considered as a rare type of cancer which causes damage to the mesothelial cells that are found covering the organs of the body. The function of mesothelium is to protect the internal organs such as heart and lungs by providing a protective membrane which covers these internal organs.
There are three regions of mesothelial cells which protect the internal organs. The first region is called pleura, (the sac which covers the lungs) and the second region is called peritoneum, (the membrane around the abdominal cavity) and the third region is called pericardium, (the sac which is found lining the heart). These three regions of mesothelial cells are attacked by three different kinds of mesothelioma cancer.
The first type is Pleural mesothelioma which attacks the pleura covering the lungs and this type is very common. Symptoms involve swollen arms and face, coughing, loss of weight and chest pain.
The second type is Peritoneal mesothelioma which attacks the peritoneum which is found covering the abdominal cavity. Symptoms involve swollen feet, nausea and abdominal bloating.
The third type is Pericardial mesothelioma which causes damage to the pericardium covering the heart and this type is very rare. Symptoms involve chest pain, cough, and palpitations.
It is known that mesothelioma cancer is linked to exposure to asbestos. Asbestos is considered as a kind of building material that is used in thermal insulation of products. Small asbestos fibers that enter the air can remain in the air for a long period of time. Just small asbestos fibers are toxic when breathed into the body.
There are three types of asbestos exposure.
The first type of asbestos exposure is known as occupational asbestos exposure and this occurs with the people who manufacture asbestos in the factories because they expose to a large amount of asbestos and they put their lives in danger.
The second type of asbestos exposure is paraoccupational asbestos exposure which is found in asbestos dust that is brought home by the worker on his clothes.
The third type of asbestos exposure is neighborhood asbestos exposure that is found in the vicinity of an asbestos manufacturing plant.
As we know mesothelioma is a rare type of cancer. In the United States, there is an average of 2,000 - 3,000 new cases that have mesothelioma every year and usually occurs in the ages that between 20-40 years old.
