Mesothelioma Explanation With Pictures
Article from here
Mesothelioma is a cancer of the mesothelium. The mesothelium is a thin membrane that lines the chest and abdomen and surrounds the organs in these areas. The lining around the lungs is called the pleura and in the abdomen it is known as the peritoneum.
About 2000 people in the UK are diagnosed with mesothelioma each year.
Mesothelioma of the lining of the lungs, known as pleural mesothelioma, is much more common than mesothelioma in the peritoneum. For every one person with peritoneal mesothelioma, there will be about 12 people who have pleural mesothelioma.
Pleural mesothelioma
The pleura has two layers: the inner (visceral) layer, which is next to the lung; and the outer (parietal) layer, which lines the chest wall. The two layers of the pleura are usually in contact and slide over each other as we breathe. The membranes produce fluid, which allows them to slide over each other easily.
When mesothelioma develops in the pleura (pleural mesothelioma), the delicate membranes thicken and may press inwards on the lung. Fluid may also collect between the two layers of the pleura: this is known as a pleural effusion.

Peritoneal mesothelioma
The lining of the abdomen is known as the peritoneum. It also has two layers: the inner (visceral) layer, which is next to the abdominal organs, and the outer (parietal) layer, which lines the abdominal wall.
If the mesothelioma is in the peritoneum it is called peritoneal mesothelioma and causes thickening of the membranes surrounding the abdominal organs and a collection of fluid in the abdomen. The collection of fluid is called ascites and causes swelling of the abdomen.

What is Mesothelioma?
The National Cancer Institute states that: "Malignant mesothelioma, a rare form of cancer, is a disease in which cancer (malignant) cells are found in the sac lining the chest (the pleura), the lining of the abdominal cavity (the peritoneum) or the lining around the heart (the pericardium)."

What is peritoneal mesothelioma?
Peritoneal mesothelioma is a cancer of the lining of the abdominal cavity. This form of cancer makes up approximately one-fifth to one-third of the total number of mesothelioma cases diagnosed. More on peritoneal mesothelioma.
How do you get Mesothelioma?
Most people with malignant mesothelioma have worked on jobs where they breathed asbestos. Others have been exposed to asbestos in a household environment, often without knowing it. More about the different ways in which people have been exposed to asbestos.
How much exposure does it take to get the disease?
An exposure of as little as one or two months can result in mesothelioma 30 or 40 years later. Mesothelioma cause.
How long does it take after exposure for the disease to show up?
People exposed in the 1940s, 50s, 60s, and 70s are now being diagnosed with mesothelioma because of the long latency period of asbestos disease.
What is the prognosis for mesothelioma?
Like most cancers, the prognosis for this disease often depends on how early it is diagnosed and how aggressively it is treated. Click on Treatment Options to find out more about traditional and new approaches.
Is there any promising research or are there promising drugs for mesothelioma?
Research is being conducted at various cancer centers all over the United States as well as by pharmaceutical companies. To find more about these studies, click on Clinical Trials. To read abstracts of the latest journal articles on mesothelioma research and to access these articles, click on Medical Journal Articles; or Mesothelioma News for news articles. A recent study of Alimta showed patients living much longer with Alitma than other chemotherapy drugs.
Where can I find information on living with mesothelioma?
Mesothelioma Aid is a good website for resource for families dealing with mesothelioma.
