Causes Of Pleural Mesothelioma
When we talk about mesothelioma, it's essential to understand that it is a type of cancer that occurs in the lining of the lungs, heart, or abdomen. Among these three types, pleural mesothelioma is the most common. It develops from the thin protective layer of tissue that covers the lungs, known as the pleura. In this article, we will discuss the causes of pleural mesothelioma.
Asbestos Exposure
Exposure to asbestos is the primary cause of pleural mesothelioma. When asbestos fibers are inhaled, they can get trapped in the pleura, causing inflammation and scarring. This scarring can eventually lead to the development of mesothelioma. Individuals who work in industries that use asbestos-containing materials are at the highest risk of exposure. These industries include construction, shipbuilding, and automotive repair.
Smoking and Asbestos Exposure
While smoking is not a direct cause of mesothelioma, it can increase the risk of developing the disease when combined with asbestos exposure. Smoking weakens the lungs, making them more vulnerable to asbestos fibers. Individuals who smoke and have a history of asbestos exposure are at a higher risk of developing pleural mesothelioma.
Asbestos in the Home
Asbestos-containing materials were commonly used in home construction until the 1980s. If a home has asbestos-containing materials, such as insulation, flooring, or roofing, these materials can release fibers into the air if they become damaged or disturbed. Individuals who live in homes with asbestos-containing materials are at risk of exposure and developing pleural mesothelioma.
Genetics
While rare, some genetic mutations are associated with an increased risk of developing mesothelioma. Inherited mutations in the BAP1 gene have been linked to an increased risk of pleural mesothelioma. Additionally, individuals with a family history of mesothelioma may be at a higher risk of developing the disease.
Radiation Exposure
Exposure to high levels of radiation can increase the risk of developing mesothelioma. Individuals who have undergone radiation therapy for other cancers may be at an increased risk of developing pleural mesothelioma.
Age and Gender
Pleural mesothelioma is most commonly diagnosed in individuals over the age of 65. Additionally, men are three to five times more likely to develop mesothelioma than women. However, it's essential to note that anyone can develop pleural mesothelioma regardless of age or gender.
FAQ
What are the symptoms of pleural mesothelioma?
Symptoms of pleural mesothelioma include shortness of breath, chest pain, persistent cough, fatigue, and weight loss.
How is pleural mesothelioma diagnosed?
Diagnosis of mesothelioma typically involves imaging tests such as X-rays, CT scans, or MRIs. A biopsy is also necessary to confirm the diagnosis.
Is pleural mesothelioma treatable?
While there is currently no cure for mesothelioma, treatment options such as surgery, chemotherapy, and radiation therapy can help manage symptoms and improve quality of life.
How long can someone live with pleural mesothelioma?
The prognosis for mesothelioma depends on several factors, including the stage of the disease at diagnosis, the age and overall health of the individual, and the type of mesothelioma. On average, individuals with pleural mesothelioma have a life expectancy of 12-21 months.
Can pleural mesothelioma be prevented?
Preventing exposure to asbestos is the best way to reduce the risk of developing pleural mesothelioma. If you work in an industry that uses asbestos-containing materials, be sure to follow safety protocols and wear protective equipment. Additionally, if you live in a home built before the 1980s, have it inspected for asbestos-containing materials.
Can pleural mesothelioma be inherited?
While rare, some genetic mutations have been linked to an increased risk of developing mesothelioma. However, pleural mesothelioma is not typically an inherited disease.
Pros
Knowing the causes of pleural mesothelioma can help individuals understand the risk factors and take steps to protect themselves from exposure. Additionally, early detection and treatment can improve outcomes and quality of life for individuals with mesothelioma.
Tips
If you work in an industry that uses asbestos-containing materials, be sure to follow safety protocols and wear protective equipment. Additionally, if you live in a home built before the 1980s, have it inspected for asbestos-containing materials.
Summary
Pleural mesothelioma is a type of cancer that develops in the lining of the lungs. Exposure to asbestos is the primary cause of pleural mesothelioma, but genetics and radiation exposure can also increase the risk. Knowing the symptoms of mesothelioma and taking steps to prevent exposure can help reduce the risk and improve outcomes for individuals with the disease.
