Mesothelioma Causes

 

What Causes Mesothelioma?

Mesothelioma is a cancer that occurs in the mesothelium, a thin membrane encompassing the body’s internal organs and cavities. Mesothelioma is caused by asbestos exposure. Asbestos fibers that are inhaled through the mouth and nose may eventually become embedded in the lining of the lungs, causing harmful inflammation of the pleura and resulting in mesothelioma or asbestosis (scar tissue formation in the lungs). It has also been found that swallowing asbestos fibers could contribute to a form of the malignancy originating in the abdomen known as peritoneal mesothelioma.

Mesothelioma Risk Factors

 

What are the risk factors for malignant mesothelioma?

There are several risk factors that increase the likelihood that a person will develop mesothelioma. The primary risk factor is asbestos exposure. Exposure to this very harmful substance can significantly enhance the chances of contracting the disease. Smoking does not have a direct causal relationship with mesothelioma but is a significant compounding factor and increases the chances of developing the disease. Other less common secondary factors include exposure to radiation, zeolite, simian virus 40 (SV40) and erionite. We discuss each of these risk factors in more detail below.

Mesothelioma Cancer

 

Mesothelioma is an aggressive cancer affecting the membrane lining of the lungs and abdomen.

Malignant mesothelioma is the most serious of all asbestos-related diseases. The primary cause and risk factor for mesothelioma is exposure to asbestos.
Making a correct mesothelioma diagnosis is particularly difficult for doctors because the disease often presents with symptoms that mimic other common ailments. There is no known cure for mesothelioma, but treatments such as surgery and chemotherapy have helped to improve the typical mesothelioma prognosis.
Pleural mesothelioma (affecting the lung’s protective lining in the chest cavity) represents about three quarters of all mesothelioma incidence. Peritoneal mesothelioma, which affects the abdominal cavity, and pericardial mesothelioma, which affects the cardiac cavity, comprise the remainder.
