What is Pleural Mesothelioma: Understanding the Deadly Disease

Rate this post

Pleural mesothelioma is a rare and aggressive cancer that affects the lining of the lungs, known as the pleura. This devastating disease is primarily caused by exposure to asbestos, a mineral once widely used in construction and other industries. Understanding the nature of pleural mesothelioma is crucial for early detection and effective treatment. In this article, we will delve into the causes, symptoms, diagnosis, treatment options, frequently asked questions, and available support for those affected by this disease.

Understanding Pleural Mesothelioma

Causes and Risk Factors

Pleural mesothelioma is primarily caused by prolonged exposure to asbestos fibers. When these microscopic fibers are inhaled, they become lodged in the pleural lining, leading to chronic inflammation and eventually the development of cancerous cells. Occupations such as construction workers, shipyard workers, and asbestos miners have a higher risk due to their direct exposure to asbestos. Additionally, individuals living in environments with high asbestos levels or those who have close family members exposed to asbestos are also at risk.

Symptoms and Early Signs

Identifying the early signs of pleural mesothelioma is crucial for timely diagnosis and treatment. However, these symptoms often mimic other less severe respiratory conditions, making it challenging to recognize the disease in its initial stages. Common symptoms include persistent coughing, chest pain, shortness of breath, fatigue, unintentional weight loss, and difficulty swallowing. If any of these symptoms persist or worsen, it is essential to seek medical attention promptly.

Diagnostic Methods

Diagnosing pleural mesothelioma requires a comprehensive evaluation that involves various diagnostic methods. These may include imaging tests like chest X-rays, CT scans, and MRIs to detect abnormalities in the pleural region. Additionally, doctors may perform a biopsy, where a small tissue sample is taken from the affected area for laboratory analysis. These diagnostic procedures help determine the stage and extent of the disease, essential for developing an effective treatment plan.

Treatment Options for Pleural Mesothelioma


Surgery plays a significant role in the treatment of pleural mesothelioma, especially in the early stages. The goal of surgery is to remove as much of the cancerous tissue as possible and potentially improve the patient’s prognosis. Procedures such as extrapleural pneumonectomy (EPP) and pleurectomy/decortication (P/D) are commonly performed. EPP involves the removal of the affected lung, pleura, and nearby tissues, while P/D aims to remove the pleura and any visible tumors while preserving the lung.

Radiation Therapy

Radiation therapy is often utilized as part of a multimodal treatment approach for pleural mesothelioma. It involves the use of high-energy radiation to target and destroy cancer cells. External beam radiation therapy is the most common technique used, where radiation is delivered from outside the body. This treatment option helps alleviate symptoms, shrink tumors, and improve the patient’s quality of life.


Chemotherapy, the use of powerful drugs to kill cancer cells, is a standard treatment option for pleural mesothelioma. It can be administered intravenously or directly into the chest cavity. Chemotherapy is often given in combination with surgery or radiation therapy to improve outcomes. While it may not cure the disease entirely, it can help manage symptoms, slow down cancer progression, and prolong survival.

Emerging Treatments

As medical research continues to advance, several emerging treatments offer hope for pleural mesothelioma patients. Immunotherapy, which stimulates the body’s immune system to recognize and attack cancer cells, has shown promising results in clinical trials. Targeted therapy, which focuses on specific genetic mutations in cancer cells, is also being explored. Clinical trials and ongoing research aim to further develop these treatment options and potentially provide more effective outcomes in the future.

Frequently Asked Questions (FAQ)

What are the primary causes of pleural mesothelioma?

Pleural mesothelioma is primarily caused by exposure to asbestos fibers. Individuals who have worked in industries where asbestos was used, or those who have lived in environments with high asbestos levels, are at higher risk.

How is pleural mesothelioma diagnosed?

Diagnosis typically involves imaging tests such as X-rays and CT scans, as well as a biopsy to analyze tissue samples. These tests help determine the extent of the disease and guide treatment decisions.

What are the available treatment options?

Treatment options for pleural mesothelioma include surgery, radiation therapy, chemotherapy, and emerging treatments like immunotherapy and targeted therapy. The choice of treatment depends on various factors, including the stage and overall health of the patient.

Can pleural mesothelioma be cured?

While there is currently no known cure for pleural mesothelioma, advancements in treatment options have significantly improved patient outcomes. Early detection and a multimodal treatment approach can help manage symptoms, prolong survival, and enhance quality of life.

Are there any alternative therapies or complementary treatments?

While alternative therapies and complementary treatments may help alleviate symptoms and improve overall well-being, it is important to discuss these options with a healthcare professional. They can provide guidance on incorporating such therapies alongside conventional treatments.

How can one prevent pleural mesothelioma?

Prevention primarily involves minimizing exposure to asbestos. This includes following safety protocols in industries where asbestos is present, using protective gear, and avoiding environments with high asbestos levels. If there is a risk of exposure, regular medical check-ups and screening may be recommended.

Support and Resources for Pleural Mesothelioma Patients

Various support groups and organizations are dedicated to providing assistance to individuals affected by pleural mesothelioma. These groups offer emotional support, educational resources, and connections to medical experts. Additionally, legal assistance may be available for those seeking compensation for asbestos-related cases. Financial resources and compensation options can help alleviate the financial burden that often accompanies the disease.


In conclusion, pleural mesothelioma is a devastating disease primarily caused by asbestos exposure. Understanding the causes, symptoms, and available treatment options is crucial for early detection and improved patient outcomes. With advancements in surgical techniques, radiation therapy, chemotherapy, and emerging treatments, there is hope for better management of this aggressive cancer. By raising awareness, providing support, and promoting further research, we can strive towards a future where pleural mesothelioma is better understood, prevented, and effectively treated.
