2. Causes of Pleural Mesothelioma

Asbestos Exposure: The Primary Cause

Asbestos exposure is the predominant cause of Pleural Mesothelioma, a cancer affecting the lining of the lungs. Asbestos, a naturally occurring mineral, was widely used in various industries due to its strength and resistance to heat and corrosion. However, when asbestos fibers are inhaled, they can become lodged in the lungs, leading to severe health issues over time.

How Asbestos Fibers Lead to Cancer

The mechanism by which asbestos fibers cause cancer involves cellular irritation and DNA damage. When these fibers enter the lungs, they irritate the cells in the pleura, the lung lining. This irritation can lead to changes in the DNA of these cells, resulting in uncontrolled growth and tumor formation. The process is typically slow, with symptoms often appearing decades after initial exposure.

Routes of Exposure: Occupational and Environmental

Exposure to asbestos can occur through various routes. Occupational exposure is common in industries such as construction, mining, firefighting, and shipbuilding, where workers may inhale asbestos fibers in the workplace. Environmental exposure can occur for those living near asbestos mines or factories, or through asbestos-containing products in homes, such as insulation or floor tiles.

Additionally, secondhand exposure is a concern for individuals living with those who work in asbestos-related environments, as fibers can be carried home on clothing or skin.

Other Potential Risk Factors

While asbestos is the primary cause, other potential risk factors for Pleural Mesothelioma exist, though they are less significant. These include exposure to radiation therapy in the chest area, infection with the simian virus SV40, and genetic predispositions. However, these factors are not as strongly linked to the disease as asbestos exposure.

It is also important to note that not everyone exposed to asbestos develops mesothelioma, suggesting that other factors, such as the extent and duration of exposure, and individual genetics, may influence disease development.
