Pleural Mesothelioma: Causes, Symptoms, and Treatments

Pleural Mesothelioma

Mesothelioma is a rare but serious form of cancer, often associated with asbestos exposure.

Among its types, pleural mesothelioma is the most common, affecting the lining of the lungs.

This guide will help you understand everything you need to know about pleural mesothelioma, from its connection to asbestos to diagnosis and treatment options.

What is Pleural Mesothelioma?

Pleural mesothelioma is a type of cancer that develops in the mesothelium, a thin layer of tissue covering the lungs.

This cancer is typically caused by inhaling asbestos fibers, which can damage the cells and lead to tumor growth.

Unlike other lung-related conditions, pleural mesothelioma specifically targets the lining of the lungs, leading to a unique set of symptoms and challenges.

The Link between Asbestos and Pleural Mesothelioma

The Role of Asbestos

Asbestos is a naturally occurring mineral used widely in the past due to its heat resistance and durability.

However, its fibers, when disturbed, can be inhaled or swallowed, causing significant health risks.

These fibers can lodge themselves in the lung lining, causing genetic changes that lead to pleural mesothelioma.

Asbestos Exposure and Risks

Exposure to asbestos is the primary risk factor for developing pleural mesothelioma. High-risk occupations include construction, mining, shipbuilding, and industries using asbestos-containing materials.

Even family members can be at risk through secondary exposure, by handling clothes contaminated with asbestos.

Signs and Symptoms of Pleural Mesothelioma

Recognizing the early symptoms of pleural mesothelioma can be challenging because they often mimic those of other less severe respiratory conditions.

Symptoms may include chest pain, difficulty breathing, persistent cough, unexplained weight loss, and fatigue.

As the disease progresses, these symptoms may become more severe, necessitating medical attention.

Diagnosis of Pleural Mesothelioma

The diagnosis of pleural mesothelioma often begins with a detailed review of the patient’s medical history and a physical examination.

This is typically followed by a series of tests including imaging tests, like X-rays or CT scans, and a biopsy where a small tissue sample is taken and examined under a microscope.

Stages of Pleural Mesothelioma

Understanding the stages of pleural mesothelioma is key to determining the appropriate treatment plan.

The disease is typically classified into four stages, with Stage 1 being the earliest and most treatable, and Stage 4 being the most advanced, where the cancer has spread to distant sites in the body.

Treatment Options for Pleural Mesothelioma


One of the main treatments for pleural mesothelioma is surgery, which aims to remove as much of the cancer as possible.

The type of surgery depends largely on the cancer’s stage and the patient’s overall health.


Chemotherapy, which uses drugs to kill cancer cells, is another common treatment. It can be used before surgery to shrink tumors or after surgery to kill remaining cancer cells.

Radiation Therapy

Radiation therapy uses high-energy beams, like X-rays, to kill cancer cells. It may be used after surgery to kill any remaining cells, or in later stages to relieve symptoms.

Emerging Treatments

Emerging treatments like immunotherapy and targeted therapy are showing promise in the fight against pleural mesothelioma.

Clinical trials are ongoing to determine their effectiveness and safety.

Living with Pleural Mesothelioma

Living with pleural mesothelioma can be challenging, but there are resources and support available to help.

From joining a support group to seeking mental health services, it’s important to remember that you’re not alone on this journey.


Understanding pleural mesothelioma is the first step towards navigating this complex disease.

Though the prognosis can be daunting, advances in treatment options offer hope to those affected.

Always consult with healthcare professionals to discuss your individual circumstances and the best course of action.
