6 Health Conditions Associated With Asbestos Exposure

Asbestos refers to a group of naturally occurring silicate minerals made up of microscopic fibers. For decades, asbestos was heavily used in various industrial and construction projects due to its durability, fire resistance, and insulating abilities. However, exposure to asbestos fibers can cause serious health issues, which is why its usage is now heavily regulated in most countries. 

When asbestos-containing materials are disturbed or damaged, microscopic fibers are released into the air, which can then be inhaled. These thin, sharp fibers can get lodged deep in the lungs, causing inflammation and scarring over time. This damage greatly increases the risk of developing certain cancers and other diseases. 

Understanding the health risks linked to asbestos exposure is critical, especially for those who may encounter asbestos in older buildings or already have through previous occupational exposure.

1. Mesothelioma

Mesothelioma is a rare and aggressive cancer that affects the lining of the lungs, abdomen, or heart. The primary cause of mesothelioma is exposure to asbestos. In fact, around 80% of mesothelioma cases are attributed to asbestos exposure. 

This cancer often develops several decades after initial exposure, which makes it difficult to trace back to asbestos as the definitive cause. The prognosis for mesothelioma is generally poor, with most patients only surviving about 12-21 months after their diagnosis. In some rare cases, life expectancy is up to 10 years. However, there is no cure. 

Though mesothelioma is rare in the general population, the rates are much higher among workers exposed to high levels of asbestos on the job, such as those working in construction, shipyards, and asbestos product manufacturing. Given the challenging nature of linking exposure to diagnosis and navigating the legal complexities, many affected individuals seek out the guidance of an asbestos law firm to help them pursue compensation and justice for their conditions. 

For treatment, options like surgery, chemotherapy, and radiation can reduce symptoms, but mesothelioma remains an extremely challenging cancer to treat.

1. Lung Cancer 

In addition to mesothelioma, asbestos exposure is also associated with an increased risk of lung cancer. In particular, exposure has been linked to a specific type of lung cancer known as non-small cell lung carcinoma. Like mesothelioma, it often takes many years following exposure for asbestos-related lung cancer to develop. 

The combination of smoking and asbestos exposure greatly compounds the risk of developing lung cancer. While early detection is key, this lung cancer is difficult to diagnose in its early stages. 

Treatment options for lung cancer typically include surgery, chemotherapy, and radiation. However, the kind attributed to asbestos has a poor prognosis in comparison to lung cancer from other causes. The only way to help decrease the risk of developing this potentially fatal cancer is by reducing exposure to asbestos and quitting smoking. 

1. Asbestosis

Asbestosis is a serious lung disease, categorized as a type of pneumoconiosis, which refers to lung damage from mineral dust exposure. 

The scarring caused by asbestos fibers restricts lung expansion, progressively leading to diminished lung function over time. Its early symptoms include shortness of breath, coughing, and chest tightness and pain. As the disease advances, severe shortness of breath and respiratory failure can also occur. 

Asbestosis increases the risk of other asbestos-related diseases like lung cancer and mesothelioma as well. There is no cure for the scarring already caused, so treatment focuses on managing symptoms and preventing further lung damage. 

Quitting smoking and avoiding other lung irritants is recommended. In severe cases, lung transplantation may be considered for treatment. 

Asbestosis is generally seen in those with prolonged, heavy asbestos exposure, such as former asbestos miners and textile workers.

1. Pleural Plaques

Pleural plaques are areas of scar tissue on the pleura, which is the thin lining surrounding the lungs. This scarring is specifically caused by exposure to asbestos fibers, which trigger inflammation and collagen deposition. 

Pleural plaques themselves do not cause symptoms or pose serious health risks. However, their presence indicates asbestos exposure and increased susceptibility to more harmful conditions like asbestosis, mesothelioma, and lung cancer. 

Those with a history of occupational exposure may be monitored for plaques via chest x-ray or CT scan. Plaques typically develop 20-30 years after exposure. Because pleural plaques point to asbestos exposure, those diagnosed will need regular screening for other related diseases. 

1. Pleural Effusion

Pleural effusion refers to a buildup of excess fluid between the layers of the pleura outside the lungs. This abnormal fluid accumulation can cause shortness of breath, chest pain, and coughing. 

There are many possible causes, and asbestos exposure is one of them. The asbestos fibers are thought to irritate the pleural space, leading to inflammation and fluid buildup. This is known as an exudative effusion, meaning the fluid has a high protein content. Malignant pleural effusions can also occur in mesothelioma patients as a complication of the cancer. The effusion may be sampled to help determine the underlying cause. 

Treatment options include draining the fluid through a chest tube or pleurodesis, which entails introducing an irritant drug into the pleural space to adhere the lungs to the chest wall. While not always a serious condition on its own, pleural effusion should prompt further evaluation to uncover any associated asbestos-related diseases.

1. Pleural Thickening

Similar to pleural plaques, pleural thickening involves the development of scar tissue on the pleura. However, pleural thickening is characterized by more extensive scarring that can involve the entire lining of the lungs. This fibrotic thickening is the result of chronic inflammation and collagen deposition induced by asbestos fibers lodged in the pleura. In some cases, the lung itself may become entrapped by the scar tissue and unable to expand properly, which can cause breathing difficulties. 

Mild cases may not have noticeable symptoms, but more advanced forms can cause shortness of breath, coughing, and chest discomfort. Although there is no specific treatment beyond managing symptoms, quitting smoking and avoiding re-exposure can prevent its aggravation. In addition, those with pleural thickening will need regular screenings for other asbestos-related conditions. 

Conclusion

In summary, asbestos exposure is associated with a number of detrimental health conditions beyond just mesothelioma and lung cancer. Thus, quitting smoking and avoiding further asbestos exposure are essential for minimizing the risks. Those affected also require close monitoring and cancer screening to detect any subsequent asbestos-related diseases early on, which is when they are most treatable. 

While asbestos use is now banned or limited, past occupational and environmental exposures still put many at risk of these health conditions. Being informed and proactive about health screenings can help mitigate the potential consequences of having been exposed to this harmful mineral.
