Causes & Risk Factors
Several factors can contribute to Pleural Mesothelioma.
Pleural mesothelioma has one overwhelming cause: asbestos exposure.
Pleural mesothelioma has one overwhelming cause: asbestos exposure. This naturally occurring mineral was widely used in construction, shipbuilding, automotive, and manufacturing industries from the 1940s through the 1980s because of its heat resistance and durability. When asbestos fibers become airborne and are inhaled, they lodge deep in the lung tissue and pleural lining, where the body cannot effectively remove them.
These microscopic fibers cause chronic inflammation and scarring over decades.
These microscopic fibers cause chronic inflammation and scarring over decades. The persistent irritation eventually triggers genetic changes in the pleural cells, leading them to grow uncontrollably and form tumors. The process is slow and insidious, which explains why symptoms typically don't appear until 20 to 50 years after the initial exposure.
While asbestos exposure accounts for about 80% of cases, researchers have identified a few other potential causes.
While asbestos exposure accounts for about 80% of cases, researchers have identified a few other potential causes. Some people develop pleural mesothelioma after exposure to erionite, a mineral fiber found in certain volcanic rocks. Radiation therapy to the chest area, certain genetic mutations, and exposure to other mineral fibers like zeolites may also contribute to a small percentage of cases. However, these alternative causes remain relatively rare compared to asbestos exposure.
Risk Factors
- Direct occupational exposure to asbestos
- Living with someone who worked with asbestos
- Military service, especially Navy personnel
- Working in shipyards, construction, or automotive repair
- Living near asbestos mines or processing plants
- Age over 65 years
- Male gender
- Previous radiation therapy to the chest
- Genetic mutations in BAP1 or other related genes
- Exposure to erionite or other mineral fibers
Diagnosis
How healthcare professionals diagnose Pleural Mesothelioma:
- 1
Diagnosing pleural mesothelioma requires multiple steps because its symptoms often mimic other lung conditions.
Diagnosing pleural mesothelioma requires multiple steps because its symptoms often mimic other lung conditions. Most patients first visit their doctor complaining of chest pain or breathing difficulties. The physician typically starts with a chest X-ray, which may show fluid buildup around the lungs or thickening of the pleural lining. However, these initial images rarely provide a definitive diagnosis.

A CT scan of the chest usually follows, offering more detailed images that can reveal the extent of pleural thickening, tumor masses, or fluid accumulation.
A CT scan of the chest usually follows, offering more detailed images that can reveal the extent of pleural thickening, tumor masses, or fluid accumulation. If these tests raise suspicion for mesothelioma, doctors often perform a thoracentesis, where they insert a needle to drain fluid from around the lungs. While this procedure can provide temporary relief from breathing problems, the fluid analysis alone rarely confirms mesothelioma.

The gold standard for diagnosis remains a tissue biopsy, which can be obtained through several methods: - Thoracoscopy (inserting a small camera through tiny incisions) - CT-guided needle biopsy - Surgical biopsy during a larger procedure.
The gold standard for diagnosis remains a tissue biopsy, which can be obtained through several methods: - Thoracoscopy (inserting a small camera through tiny incisions) - CT-guided needle biopsy - Surgical biopsy during a larger procedure. Pathologists then examine the tissue samples using special stains and molecular markers to distinguish mesothelioma from lung cancer or other conditions. This process can take several days to weeks, but accurate diagnosis is essential since treatment approaches differ significantly between mesothelioma and other chest cancers.
Complications
- Pleural mesothelioma creates several serious complications that can significantly impact breathing and overall quality of life.
- Pleural effusion, the buildup of fluid between the lung and chest wall, occurs in most patients and can cause severe shortness of breath.
- This fluid often reaccumulates quickly even after drainage procedures, requiring repeated interventions or permanent drainage systems.
- As the cancer progresses, it can invade nearby structures including the chest wall, diaphragm, and heart lining.
- This spread can cause intense pain that becomes increasingly difficult to manage with standard pain medications.
- The tumor may also compress major blood vessels or the esophagus, leading to swelling in the arms and face or difficulty swallowing.
- Treatment-related complications from surgery, chemotherapy, and radiation can include infection, blood clots, kidney problems, and severe fatigue that may persist for months.
Prevention
- Since asbestos exposure causes the vast majority of pleural mesothelioma cases, prevention centers on avoiding contact with this dangerous mineral.
- For people working in high-risk occupations, following proper safety protocols is essential: wearing appropriate respiratory protection, using proper ventilation systems, and following decontamination procedures when leaving work sites.
- Home renovation projects pose particular risks because many older buildings contain asbestos in insulation, floor tiles, roofing materials, and pipe wrapping.
- Before disturbing these materials, homeowners should hire certified professionals to test for asbestos presence.
- If asbestos is found, only licensed abatement specialists should handle its removal.
- DIY removal attempts can create dangerous fiber clouds that put entire families at risk.
- For those with known past exposure, prevention shifts to early detection through regular medical monitoring.
- While no screening test can prevent mesothelioma from developing, staying alert to symptoms and maintaining regular contact with healthcare providers familiar with asbestos-related diseases can lead to earlier diagnosis and potentially better treatment outcomes.
Treatment for pleural mesothelioma typically involves a multidisciplinary approach combining surgery, chemotherapy, and radiation therapy.
Treatment for pleural mesothelioma typically involves a multidisciplinary approach combining surgery, chemotherapy, and radiation therapy. The specific combination depends on the cancer's stage, the patient's overall health, and their personal preferences. For patients with early-stage disease and good physical condition, aggressive multimodal therapy offers the best chance for extended survival.
Surgical options include pleurectomy with decortication, which removes the pleural lining and visible tumors while preserving the lung, or extrapleural pneumonectomy, a more extensive procedure that removes the entire affected lung, pleural lining, and nearby tissues.
Surgical options include pleurectomy with decortication, which removes the pleural lining and visible tumors while preserving the lung, or extrapleural pneumonectomy, a more extensive procedure that removes the entire affected lung, pleural lining, and nearby tissues. These operations require significant recovery time but can substantially reduce tumor burden when combined with other treatments.
Chemotherapy forms the backbone of treatment for most patients, whether combined with surgery or used alone for advanced cases.
Chemotherapy forms the backbone of treatment for most patients, whether combined with surgery or used alone for advanced cases. The standard regimen combines pemetrexed and cisplatin, administered intravenously every three weeks. Newer treatment options include: - Immunotherapy drugs like pembrolizumab and nivolumab - Targeted therapy for specific genetic mutations - Heated chemotherapy delivered directly into the chest cavity during surgery - Clinical trials testing novel drug combinations.
Recent breakthroughs in immunotherapy have shown particular promise, with some patients experiencing longer survival times than previously possible.

Radiation therapy often plays a supportive role, helping control pain and prevent tumor spread to surgical sites. Palliative treatments, including procedures to drain recurring fluid buildup and pain management strategies, remain crucial for maintaining quality of life throughout treatment.
Living With Pleural Mesothelioma
Living with pleural mesothelioma requires adapting daily routines to manage symptoms while maintaining the best possible quality of life. Breathing exercises, pulmonary rehabilitation, and using supplemental oxygen when needed can help manage shortness of breath. Many patients find that sleeping with their head elevated and using a humidifier improves nighttime comfort.
