mesothelioma cancers

Most of your internal organs are covered with a thin layer of tissue called Mesothelium. Mesothelioma is a cancer that affects these thin layers of tissues.

Doctors divide mesothelioma into different types based on what part of the mesothelium is affected, including:

• Pleural malignant mesothelioma, this is the most common form of mesothelioma that affects people.
• Peritoneal mesothelioma, which occurs in the tissue in your abdomen.
• Pericardial mesothelioma, is found affecting the tissues around the heart.
• Mesothelioma of the tunica vaginalis, is found in the lining of the testicles.

Between 2,000 and 3,000 people are diagnosed with mesothelioma in the United States each year, according to the American Cancer Society.

In general, cancer begins when a series of genetic mutations occur within a cell, causing the cell to grow and multiply out of control, when healthy cells would normally die. The accumulating abnormal cells form a mass (tumor). Cancer cells invade nearby tissues and can break off from an initial tumor to spread elsewhere in the body (metastasize).

Most of the people who develop Mesothelioma have at one point or another been exposed to asbestos or have worked in jobs where they have been exposed to or have worked with asbestos, and asbestos fibers. Asbestos is a mineral that's found naturally in the environment. Asbestos fibers are strong and resistant to heat, making them useful in a wide variety of applications, such as in insulation, cement, brakes, shingles, flooring and many other products. People who work around asbestos fibers are thought to have the greatest risk of mesothelioma.

When asbestos is broken up or disturbed, such as during the mining process or when removing asbestos insulation, dust may be created. If the dust is inhaled or swallowed, the asbestos fibers may settle in the lungs or in the stomach, where they can cause irritation that may lead to mesothelioma, though how exactly this happens isn't understood.

Some people with years of asbestos exposure never develop mesothelioma. And yet, others with very brief exposure develop the disease. This indicates that other factors may be involved in determining whether someone gets mesothelioma or doesn't. For instance, you could inherit a predisposition to cancer or some other condition could increase your risk. Even having cancer run in your family or not can be a determining factor in whether or not you develop mesothelioma. People who smoke can intensify their risks of developing the cancer as well. There really is no pinpoint answer for why some people who have been exposed to asbestos develop mesothelioma and why some others who have been exposed to it never develop it.

Symptoms of mesothelioma may not appear until 20 to 50 years after exposure to asbestos.Mesothelioma that progresses can lead to death.

Possible Signs and Symptoms of Mesothelioma

• Painful breathing (pleurisy)
• Painful coughing
• Chest pain under the rib cage
• Unusual lumps of tissue under the skin on your chest
• Unexplained weight loss
• Dry (nonproductive) cough
• Abdominal pain
• Abdominal swelling
• A change in your bowel habits, such as more frequent diarrhea or constipation
• Lumps of tissue in the abdomen
• Unexplained weight loss

 There are a number of ways to have Mesothelioma treated. Your doctor will plan out the best treatment for you. Unfortunately, mesothelioma often is an aggressive disease and for most people a cure isn't possible. Mesothelioma is usually diagnosed at an advanced stage — when it isn't possible to remove the cancer through an operation. Instead, your doctor may work to control your cancer to make you more comfortable. Surgery, chemotherapy, radiation therapy, combination therapy, and clinical trials are all ways that can be used to treat the cancer. As stated above it is not always possible to get rid of the cancer because it takes so long to show itself, and once it does, it is often at an advanced stage, where not much can be done. Some people with years of asbestos exposure never develop mesothelioma. And yet, others with very brief exposure develop the disease. This indicates that other factors may be involved in determining whether someone gets mesothelioma or doesn't. For instance, you could inherit a predisposition to cancer or some other condition could increase your risk. Prevention is the best way to beat this cancer. Be aware of the safety regulations at work, some older homes have asbestos and if your home does, make sure that the asbestos is not disturbed in anyway. Only a trained professional can remove asbestos from your home safely. do not try to take on its removal by yourself, you could expose yourself as well as your family to the fibers which can cause mesothelioma.
