Mesothelioma FAQ - (Frequently Asked Questions)

What is Mesothelioma?

According to the National Cancer Institute, "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) or the abdomen."

What causes Mesothelioma?

Mesothelioma is a very rare cancer most often caused by exposure to asbestos fibers that embed themselves into the lungs and the abdomen. Most people who have malignant mesothelioma have worked on jobs where asbestos was present. Others can also be exposed to asbestots in a household environment without even knowing it.

How long does it take after exposure for the disease show up?

People who were exposed in the 1940's, 50's, 60's and 70's are now being diagnosed with mesothelioma because of the long latency period of asbestos disease.

How much exposure does it take to get the disease?

Exposure as little as one or two months may result in mesothelioma 30 to 40 years later.

How is Mesothelioma Diagnosed?

The way mesothelioma is diagnosed is by pathological examination. Tissue is removed and put under a microscope. A pathologist makes a definitive diagnosis and issues a pathology report. Common symptoms resulting to this procedure usually include: shortness of breath, fluid build-up or pleural effusions, chest pain or swelling/pain in the abdomen. The doctor may offer an x-ray or a CT Scan of the abdomen and chest. Further tests can be done if additional examination is needed which include:

• Thoracoscopy (An instrument called the Thoracoscope is used to look inside the chest cavity. The test is usually done in a hospital with local anesthetics or painkillers)
• Peritoneoscopy (The doctor may look inside the abdomen with a special tool called a Peritoneoscope. The peritoneoscope is placed into an opening made in the abdomen. The test is usually done at a hospital under a local anesthetic)
• Biopsy (If there is any abnormal tissue found, the doctor will need to cut out a small piece and have it looked under a microscope. Because Mesothelioma is a very complicated diagnosis many hospitals send the pathology off to experts.

What is Asbestos?

Asbestos is an extremely toxic fibrous mineral when it is inhaled, absorbed or ingested. It is found in the ground and is mined all over the world. When asbestos fibers are taken into the body it can cause ailments like mesothelioma and other problems such as asbestosis as well as a number of cancers. Extended exposure to asbestos is usually needed to develop a problem.

Is there a difference between Tobacco Related Cancer & Mesothelioma?

Mesothelioma affects the lungs but is not considered lung cancer. Since smokers are at risk for lung cancer it can lead to contracting other asbestos related diseases. Lung cancer is more common arising in the lungas inner tissues opposed to mesothelioma which develops in the tissue covering the lung.
