What Causes Mesothelioma Lung Cancer?

The Silent Killer: Understanding Mesothelioma Lung Cancer

Welcome, dear reader. Today, we will discuss one of the most fatal and insidious forms of lung cancer, mesothelioma. Mesothelioma is an aggressive and rare form of lung cancer, caused by exposure to asbestos fibers. This cancer is notorious for remaining undetected until it reaches its advanced stages, resulting in a poor prognosis for patients diagnosed with it.

In this article, we will delve deeper into mesothelioma, exploring the causes of this deadly disease, its impact on the human body, and finally, what steps we can take to prevent this cancer from spreading any further.

The Facts: Understanding Mesothelioma Lung Cancer

Mesothelioma is a cancer that forms in the lining of the lungs, heart, or abdomen. The primary cause of mesothelioma is exposure to asbestos, a mineral fiber that was once widely used in the construction, automotive, naval, and industrial sectors.

Asbestos fibers are microscopic, and when inhaled, they become embedded in the lining of the lungs, heart, or abdomen, causing inflammation and scarring that can ultimately lead to cancer.

While asbestos has been banned in many countries, it still exists in many older buildings and products, making people who work or live in such environments susceptible to developing mesothelioma.

Causes of Mesothelioma Lung Cancer

1. Asbestos Exposure

The primary cause of mesothelioma is prolonged exposure to asbestos fibers. Once inhaled, these fibers can remain in the lungs for decades, causing inflammation and scarring that can lead to the development of mesothelioma.

Asbestos exposure is most common in those who work in the following industries:

Industry Description
Construction Asbestos was widely used in the construction industry for insulation, cement, and roofing products until the 1970s.
Automotive Asbestos was commonly used in brake pads, clutches, and gaskets until the late 1990s.
Naval Asbestos was used extensively in the construction of naval ships until the 1970s.
Industrial Asbestos was used in various industrial applications, such as the manufacture of textiles and plastics.

2. Genetic Factors

While rare, there are genetic factors associated with mesothelioma. Studies have found that certain genes may increase an individual’s susceptibility to developing mesothelioma, although more research is needed to fully understand the link between genetics and mesothelioma.

3. Environmental Factors

Environmental factors such as exposure to radiation or certain chemicals may increase an individual’s risk of developing mesothelioma. However, these factors are not as significant as asbestos exposure when it comes to causing mesothelioma.

Frequently Asked Questions

1. How long does it take for mesothelioma to develop?

The incubation period for mesothelioma is long, typically taking between 20 and 50 years to develop after exposure to asbestos.

2. What are the early signs of mesothelioma?

The early signs of mesothelioma can be non-specific, such as shortness of breath or chest pain. As the cancer progresses, symptoms may include coughing, fatigue, and weight loss.

3. Can mesothelioma be cured?

At present, there is no known cure for mesothelioma. Treatment options include chemotherapy, radiation, and surgery, but the prognosis for mesothelioma patients remains poor.

4. Can mesothelioma be prevented?

The best way to prevent mesothelioma is to avoid exposure to asbestos fibers. If you work in an industry where asbestos exposure is prevalent, ensure you take the necessary precautions such as wearing protective clothing and masks.

5. Can family members of those exposed to asbestos develop mesothelioma?

While it is rare, family members of those exposed to asbestos may have an increased risk of developing mesothelioma due to second-hand exposure.

6. What is the average life expectancy for someone diagnosed with mesothelioma?

The average life expectancy for someone diagnosed with mesothelioma varies depending on how advanced the cancer is at diagnosis. On average, mesothelioma patients survive between 12 and 21 months after diagnosis.

7. Can children develop mesothelioma?

Mesothelioma primarily affects middle-aged and older adults who have been exposed to asbestos. While it is rare, children can develop mesothelioma if they are exposed to asbestos at a young age.

8. What should I do if I have been exposed to asbestos?

If you have been exposed to asbestos, seek medical attention immediately. Even if you do not have any symptoms, it is critical to monitor your health and get regular check-ups to ensure early detection of any potential health issues.

9. Is smoking a risk factor for mesothelioma?

While smoking is not a direct cause of mesothelioma, it can increase an individual’s risk of developing lung cancer, which in turn can make it more challenging to diagnose mesothelioma early.

10. How is mesothelioma diagnosed?

Mesothelioma is typically diagnosed using a combination of imaging tests, such as CT scans and X-rays, and biopsies to confirm the presence of cancer.

11. What are the treatment options for mesothelioma?

There are several treatment options available for mesothelioma, including chemotherapy, radiation, and surgery. The most effective treatment plan will depend on the stage and severity of the cancer.

12. Can mesothelioma spread to other parts of the body?

Yes, mesothelioma can spread to other parts of the body, depending on where the cancer originated.

13. What is the prognosis for mesothelioma patients?

Unfortunately, the prognosis for mesothelioma patients remains poor, with an average survival time of just 12 to 21 months after diagnosis.


Mesothelioma lung cancer is a devastating disease that can only be prevented through awareness, education, and action. Though it is a rare form of cancer, those who are exposed to asbestos, particularly those in high-risk industries, are at great risk of developing this deadly disease. We must take the necessary precautions to protect ourselves and our loved ones from this silent killer.

If you have been exposed to asbestos or are experiencing any symptoms associated with mesothelioma, seek medical attention immediately. Remember, early detection is key to improving your chances of survival.
