## 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.
