Malignant Mesothelioma: Symptoms, Causes, Diagnosis, and Treatment | AIROC Hospitals

About Malignant Mesothelioma – Overview and Types

Malignant mesothelioma is a rare and aggressive cancer that develops in the mesothelium, the thin layer of tissue that lines and protects several major organs, including the lungs, abdomen, and heart. It is most strongly associated with long-term exposure to asbestos and often takes several decades to develop after initial exposure. At AIROC Hospitals, our thoracic and surgical oncology specialists provide comprehensive, multidisciplinary care to diagnose and manage mesothelioma, focusing on both extending survival and preserving quality of life.

Because mesothelioma has a long latency period between exposure and diagnosis, and its early symptoms can be subtle or mistaken for other conditions, it is often identified at a more advanced stage. Our team at AIROC Hospitals emphasizes thorough evaluation and coordinated care to give patients access to the most effective treatment options available.

Types of Malignant Mesothelioma

Malignant mesothelioma is classified based on the location in which it develops:

• Pleural Mesothelioma – The most common form, affecting the lining of the lungs and chest cavity (pleura), accounting for the majority of cases.
• Peritoneal Mesothelioma – Develops in the lining of the abdominal cavity (peritoneum), the second most common form.
• Pericardial Mesothelioma – A rare type affecting the lining surrounding the heart (pericardium).
• Testicular Mesothelioma – An extremely rare form affecting the lining surrounding the testicles.

Mesothelioma is further categorized by cell type — epithelioid, sarcomatoid, or biphasic (a mix of both) — which significantly influences treatment approach and expected outcomes. Identifying both the location and cell type is essential, and our specialists at AIROC Hospitals ensure precise pathological evaluation for every patient.

 

Symptoms and Causes

Common Symptoms of Malignant Mesothelioma

Symptoms of mesothelioma vary depending on the affected location and often appear only after the disease has progressed:

Pleural Mesothelioma:

• Chest pain
• Shortness of breath
• Persistent cough
• Unexplained weight loss
• Fatigue
• Fluid buildup around the lungs

Peritoneal Mesothelioma:

• Abdominal pain or swelling
• Nausea and vomiting
• Changes in bowel habits
• Unexplained weight loss
• A palpable abdominal mass or fluid buildup

Because these symptoms are often nonspecific and can resemble more common conditions, individuals with a known history of asbestos exposure who develop persistent respiratory or abdominal symptoms should seek prompt evaluation.

Causes and Risk Factors

Malignant mesothelioma has a well-established primary cause, along with several contributing risk factors:

• Asbestos Exposure: The leading cause of mesothelioma, with risk increasing based on the duration and intensity of exposure. This can occur through occupational settings such as construction, shipbuilding, mining, and manufacturing, or through secondary exposure from contaminated clothing.
• Latency Period: Mesothelioma often develops 20 to 50 years after initial asbestos exposure, making a detailed occupational and environmental history important for diagnosis.
• Radiation Exposure: Prior radiation therapy to the chest or abdomen has been linked to a small increased risk.
• Genetic Factors: Certain inherited genetic mutations may increase susceptibility to mesothelioma, particularly among individuals with lower levels of asbestos exposure.
• Age and Sex: More commonly diagnosed in older adults and occurs more frequently in men, largely reflecting historical patterns of occupational asbestos exposure.

Understanding an individual's asbestos exposure history is central to risk assessment, and our specialists at AIROC Hospitals take a detailed exposure history as part of every evaluation.

 

Diagnosis and Treatment

How Malignant Mesothelioma Is Diagnosed

At AIROC Hospitals, we use a combination of imaging, laboratory, and tissue-based techniques to accurately diagnose and stage mesothelioma:

• Imaging Tests: CT, MRI, and PET scans help identify abnormal thickening or masses in the pleura, peritoneum, or pericardium and assess the extent of disease.
• Biopsy: A tissue sample, often obtained through minimally invasive procedures such as thoracoscopy or laparoscopy, is examined to confirm the diagnosis and cell type.
• Fluid Analysis: If fluid has accumulated around the lungs or abdomen, it may be drained and analyzed for cancerous cells.
• Blood Tests: Certain biomarkers may support diagnosis and help monitor treatment response, though they are not definitive on their own.
• Detailed Exposure History: A thorough review of occupational and environmental asbestos exposure supports accurate diagnosis and staging.

Treatment Options at AIROC Hospitals

Treatment for malignant mesothelioma is tailored to the tumor's location, stage, cell type, and the patient's overall health, and may include:

• Surgery: May involve removing the tumor and affected tissue, ranging from more limited procedures to extensive surgery aimed at removing as much visible disease as possible, depending on the extent and location of the cancer.
• Chemotherapy: Often used as a primary treatment, either alone or in combination with surgery, to target cancer cells throughout the affected area.
• Radiation Therapy: Used to relieve symptoms, target specific areas of disease, or reduce the risk of recurrence after surgery.
• Immunotherapy: An increasingly important option for advanced mesothelioma, helping the immune system recognize and attack cancer cells.
• Heated Intraperitoneal Chemotherapy (HIPEC): A specialized treatment used for peritoneal mesothelioma, delivering heated chemotherapy directly into the abdominal cavity following surgery.
• Palliative Care and Symptom Management: Given the advanced stage at which mesothelioma is often diagnosed, dedicated symptom relief — including management of fluid buildup and pain — is an important part of care.

Our multidisciplinary team at AIROC Hospitals — including thoracic surgeons, surgical oncologists, and radiation and medical oncology specialists — works together to design a treatment plan aimed at extending survival while maintaining the best possible quality of life.

 

Prevention and Risk Factors

Because malignant mesothelioma is strongly linked to asbestos exposure, prevention focuses primarily on minimizing contact with this substance:

• Avoiding Asbestos Exposure: The most effective preventive measure, particularly in occupational settings where asbestos may still be present in older buildings or materials.
• Following Workplace Safety Guidelines: Using appropriate protective equipment and adhering to safety protocols when working in industries with potential asbestos exposure.
• Proper Asbestos Removal: Ensuring that asbestos-containing materials are safely handled and removed by trained professionals rather than disturbed directly.
• Awareness of Secondary Exposure: Taking precautions to prevent bringing asbestos fibers home on clothing or equipment from occupational settings.
• Monitoring for High-Risk Individuals: Those with a known history of significant asbestos exposure should remain aware of respiratory or abdominal symptoms and seek prompt evaluation if they occur.

At AIROC Hospitals, we encourage individuals with a history of asbestos exposure to remain vigilant about new or persistent symptoms, as early evaluation — even years after exposure — plays an important role in guiding timely diagnosis and treatment.
