What is Mesothelioma?

Mesothelioma is a rare cancer that starts in the mesothelium, which includes the pleura, the thin layer of tissue that lines the lungs; the pericardium, the sac around the heart; and the peritoneum, the membrane that lines the abdomen.

About Mesothelioma:

Most cases start in the pleura. This type is also called malignant pleural mesothelioma (MPM).

Causes include :

Mesothelioma almost always is caused by past exposure to fibers of asbestos. Asbestos is a fibrous mineral that in the past was used in the construction, automotive, military, marine and manufacturing industries.

When tiny particles of asbestos are made or disturbed, they can float in the air. People can breathe in the asbestos or swallow it. This may lead to serious health conditions such as cancers of the lung, larynx and kidney. It also can cause asbestosis, a non-cancerous, chronic lung disease.

In some people, asbestos fibers cause genetic changes in the pleura, the thin layer of tissue that lines the lungs. These changes may lead to mesothelioma. It can occur 20 to 50 years after a person has come in contact with asbestos.
In rare cases,  It can be passed down from one generation to the next. Genetic counseling may be right for you.

Anything that increases your chance of getting mesothelioma is a risk factor. The only known risk factor is contact with asbestos. It is more common in men, mainly those between 45 and 85 years old.
Not everyone with risk factors gets It. However, if you have been exposed to asbestos, it’s a good idea to tell your doctor.
