Everything You Need to Know About Pleural Mesothelioma
Important Facts About Pleural Mesothelioma Risk Factors
- The main risk factor for pleural mesothelioma is exposure to asbestos. It is the only cause of mesothelioma.
- All other pleural mesothelioma risk factors are related to asbestos exposure: military service, use of talc products, occupation, gender, residency and age.
- Males are often most susceptible to asbestos exposure due to the likelihood of working in at-risk occupations, such as construction, the military.
Why Asbestos is the Main Risk Factor for Pleural Mesothelioma
Exposure to asbestos is the only cause of pleural mesothelioma, which is a rare cancer that forms in a thin tissue layer near the lungs. Asbestos is a naturally forming mineral in the earth’s soil. The mineral is durable and fire-resistant, which made it a valuable addition to homes and offices. Asbestos was mixed with paint, added to roof shingles, floor tiles, and siding, used to insulate electrical wiring, added to automobile brakes, and more.
While asbestos can be helpful in improving the durability of buildings, vehicles or Navy ships, it’s also dangerous and capable of causing cancer. When asbestos breaks apart, very fine and sharp fibers float in the air.
These fibers can be inhaled (breathed in) or ingested (swallowed). If the fibers travel through the body, they can get stuck in a thin lining called the pleura. The pleura is located between the lungs and chest wall.
Asbestos fibers that get stuck in this lining can cause cells to mutate and turn cancerous. Cancer that originates in the pleura is called pleural mesothelioma.
What Are Other Pleural Mesothelioma Risk Factors?
The main risk factors for pleural mesothelioma all are associated with asbestos exposure – as in, the likelihood of someone being exposed. Exposure to asbestos is not a random event. There are certain types of jobs that are more prone to handling asbestos or working near asbestos in a building, automobile, plane or ship.
Frequently Asked Questions About Pleural Mesothelioma Risk Factors
What Are the Risk Factors for Pleural Mesothelioma?
The main risk factor for pleural mesothelioma is exposure to asbestos, which is the only proven cause of pleural mesothelioma. The other risk factors are all associated with the likelihood of someone being exposed to asbestos. These risks include: occupation, military service, gender and residency.
How Common Is Pleural Mesothelioma?
Pleural mesothelioma is not a common cancer at all, although it is the most common type of mesothelioma. There are only around 2,500 cases of mesothelioma in the United States each year. Pleural mesothelioma accounts for roughly 2,000 of these cases, making it one of the rarest cancers.
What Are the Pleural Mesothelioma Risk Occupations?
The top pleural mesothelioma risk occupations are construction, insulation, electrical work, automobile repair, plumbers, pipefitters and shipbuilders. Other occupations, such as firefighters, bakers, hairdressers and plant workers, also have a risk of asbestos exposure.

AI Summary of Pleural Mesothelioma Risk Factors
Pleural mesothelioma is a rare form of cancer that affects the lining surrounding the lungs, known as the pleura. Understanding the risk factors associated with this disease can help inform awareness and early detection efforts. The primary risk factor for pleural mesothelioma is exposure to asbestos, a mineral once widely used in construction, insulation, and various industrial applications due to its heat resistance and durability. When asbestos fibers are released into the air and inhaled, they can become embedded in the pleura, causing cellular changes that may lead to cancer many years later. This process often takes several decades, which is why pleural mesothelioma typically appears in individuals in their 50s and older.
Other factors that can increase the likelihood of developing pleural mesothelioma are related to occupational and environmental exposure. Certain jobs such as construction, shipbuilding, electrical work, automobile repair, and work in insulation or pipefitting are known to have higher risks because workers in these fields were more likely to encounter asbestos materials. Military veterans, especially those who served during wartime, represent a significant portion of cases because asbestos was commonly used in shipyards and military equipment. Geographical locations with asbestos mines or naturally occurring deposits, like Libby, Montana, also pose environmental risk to residents. Additionally, the use of talcum powders contaminated with asbestos has been linked to increased exposure, as talc and asbestos can sometimes be found together during mining.
Gender also plays a role because historically, men have been more involved in occupations with high asbestos exposure, making males disproportionately affected by the disease. Age is a factor because the disease takes many years to develop after exposure, so most diagnosed individuals are in their older years. Overall, understanding these risk factors helps highlight the importance of awareness and precaution in environments where asbestos exposure is possible, even decades after the original contact. While pleural mesothelioma remains a rare cancer, recognizing its risk factors can aid in early diagnosis and prompt medical attention for those most vulnerable.
