What is Mesothelioma?

Mesothelioma is a type of cancer. It is a cancer of mesothelial cells. These cells cover the outer surface of most of our internal body organs, forming a lining that is sometimes called the mesothelium. So this is where this type of cancer gets its name.
Mesothelioma cancer can develop in the tissues covering the lungs or the abdomen.

How is mesothelioma treated?

Treatment for mesothelioma depends on the location of the cancer, the stage of the disease, and the patient's age and general health. Standard treatment options include surgery, radiation therapy, and chemotherapy. Sometimes, these treatments are combined.

To relieve symptoms and control pain, the doctor may use a needle or a thin tube to drain fluid that has built up in the chest or abdomen. The procedure for removing fluid from the chest is called thoracentesis. Removal of fluid from the abdomen is called paracentesis.

Type of Mesothelioma

Mesothelioma in the chest

The tissues lining (or covering) the lungs are called the pleura. There are two pleura. These can be called pleural membranes. The gap between them is called the pleural space. The pleura are fibrous sheets. They help to protect the lungs.
Mesothelioma is most often diagnosed in the pleura. This is known as pleural mesothelioma. Because it is so close, pleural mesothelioma can also affect the sheet of tissue covering the heart - the pericardium. Doctors call the pericardium the lining, although it is on the outside of the heart.

Mesothelioma in the abdomen

The tissue lining the abdomen (tummy) is called the peritoneum. It helps to protect the contents of the abdomen. It also produces a lubricating fluid. This helps the organs to move smoothly inside the abdomen as we move around. Mesothelioma of the tissues lining the abdominal cavity is known as peritoneal mesothelioma. It is much less common than pleural mesothelioma. It is unusual for mesothelioma to spread to other parts of the body. But if it does, it does not usually cause troublesome symptoms.
