Mesothelioma

What is mesothelioma?

Mesothelioma is cancer of the tissue that lines many of the organs in the body. This lining is called the mesothelium. Mesothelioma is a rare type of cancer that is very serious.

There are a few types of mesothelioma:

• Pleural mesotheliomas occur in the lungs or chest area. This is by far the most common type.
• Peritoneal mesotheliomas are found in the abdomen. This type is rare but is the second most common.
• Pericardial mesotheliomas affect the lining around the heart. This type is very rare.
• Mesotheliomas of the tunica vaginalis are found in the testicles. This type is also very rare.

What are the symptoms of mesothelioma?

Symptoms of mesothelioma can vary depending on where in the body they occur. Symptoms may include:

• Shortness of breath
• Cough
• Pain in the chest
• Trouble swallowing
• Pain in the stomach
• Nausea and vomiting
• Weight loss

How is mesothelioma treated?

Mesothelioma is a fast-growing cancer that is often not found until it is in its later stages. This can make it hard to treat. Possible treatments may include:

• Surgery to remove as much of the cancer as possible.
• Radiation therapy to destroy cancer cells that are left after surgery and to help ease the symptoms of the cancer.
• Chemotherapy to shrink the tumor before surgery or to help kill any remaining cancer cells after surgery.
• Immunotherapy to help stimulate the immune system to fight the cancer.
• Targeted therapy to attack the cancer cells directly.

What are the risk factors for mesothelioma?

The main risk factor for mesothelioma is being exposed to high levels of asbestos. Asbestos is a mineral used in many products, including brakes, insulation, shingles, and flooring. When the small fibers break off, they can be inhaled and travel to the lungs.
