Para occupational secondary exposure

Family members of people who worked with asbestos and brought the dust home on their clothes have also sometimes developed mesothelioma.Washing the clothes of a family member who worked with asbestos can also put a person at risk for developing mesothelioma.

Occasionally, mesothelioma develops in people who have never been exposed to asbestos.
Mesothelioma is not contagious and cannot be passed on to other people. It is not caused by inherited faulty genes and so family members do not have an increased risk of developing it, unless they have been in contact with asbestos.

Smoking and Asbestos Exposure

The combination of tobacco smoking and exposure to asbestos can greatly increase the risk factor for developing mesothelioma. The Kent brand of cigarettes used asbestos in its filters for the first few years of production in the 1950s and some cases of mesothelioma have resulted. Smoking modern cigarettes does not appear to increase the risk of mesothelioma.

Chronic inflammation

Heavy metals – nickel and beryllium

Chemical agents – Diethylstilboestrol.

Asbestos exposure:

Asbestos exposure is the primary risk factor for mesothelioma. Asbestos is a group of minerals once used in industrial and construction materials, but is now produced in small quantities. Working with asbestos is the major risk factor for mesothelioma.

Most people who develop mesothelioma have worked on jobs where they inhaled asbestos particles, (The occupations most associated with mesothelioma are shipyard workers, electricians, plumbers, construction industry workers, pipefitters, boilermakers, and anyone subject to heavy exposure to dangerous asbestos and airborne asbestos fibers) or they have been exposed to asbestos dust and fiber in other ways.

An abundance of cases have also demonstrated that mesothelioma can develop among people who lived in communities where asbestos factories or mines were located. In some instances, entire towns have been adversely affected by the presence of asbestos fibers in the air.

Asbestos is also fire-retardant and was used in many fire-protective materials. Unfortunately, because of its fibrous nature (and because of the brittle nature of these fibres) asbestos particles are readily released into the air (most especially during the manufacturing process) and these are readily inhaled or swallowed. Being needle-like these can stick into and irritate the pleural membranes of the lungs and the peritoneum of the abdomen. Continuous irritation can lead to inflammation and ultimately to cancer.
In addition to mesothelioma, exposure to asbestos increases the risk of lung cancer, asbestosis (a noncancerous, chronic lung ailment), and other cancers, such as those of the larynx and kidney.

Mesothelioma is an incurable asbestos cancer. This short film was produced to raise awareness of the issues around mesothelioma. It includes interviews with people who have the disease. It was produced for Action Mesothelioma day on belhalf of Forum of Asbestos Victim Support Groups. For more information visit www.ActionMeso.info

There are three Types of Mesothelioma: epitheloid, sarcomatoid, and biphasic. In this video Mary Hesdorffer, a nurse practitioner and Medical Liaison for the Mesothelioma Applied Research Foundation (www.curemeso.org), gives an overview of how the different types of mesothelioma can affect the lungs and abdomen.

Pericardial Mesothelioma is the rarest form of the asbestos-related cancer. Approximately 5 percent of all mesothelioma cases are pericardial. It is associated with long term exposure to asbestos fibres. This form of mesothelioma develops in the lining of the heart, known as the pericardium. The heart, as with any organ that requires constant movement to work properly, requires constant lubrication. Lubrication comes in the form of a thin layer of mucous, and in normal systems the heart beats on as normal.

As in the lung, the rapid growth of the cancerous tumors can cause expansion of the tissue and accumulation of fluid. The fluid can interfere with the functioning of the heart and cause chest pain. People in the fourth to seventh decades of life are most likely to have this cancer, and there is a 2:1 male to female ratio.

Peritoneal mesothelioma is the second most common type of malignant mesothelioma. Peritoneal mesothelioma is the name given to the cancer that attacks the lining of the abdomen. Peritoneal mesothelioma is most often caused by the ingestion of carcinogenic asbestos fibers.

Comprising approximately 25 percent of mesothelioma cases, this form of mesothelioma develops in the lining of the abdominal cavity, known as the peritoneal membrane. The collection of cells surrounds the gastrointestinal tract and provides lubrication for the stomach and intestines to move so that they may function properly. These organs must be able to move properly in order to properly digest and process food, and a failure in the peritoneum can result in severe and debilitating consequences.
