Mesothelioma is a rare and aggressive cancer caused primarily by exposure to asbestos. This disease originates in the mesothelium, a thin membrane that lines various organs in the body. Mesothelioma is categorized into three main types based on where it develops: pleural (lungs), peritoneal (abdomen), and pericardial (heart). Each type has distinct symptoms, treatment approaches, and prognoses, making it crucial to understand these differences for effective care.
This page provides a summary of each mesothelioma type. You can click the links for detailed information about symptoms, causes, treatment options, and emerging research for each.
Pleural Mesothelioma
Pleural mesothelioma is the most common form of this disease, accounting for approximately 75% of all cases. It develops in the pleura, a thin tissue lining the lungs. The primary cause is inhalation of asbestos fibers, which embed themselves in the lung lining, causing inflammation, scarring, and, over time, cancer.
Common Symptoms of Pleural Mesothelioma
- Persistent chest pain
- Shortness of breath
- Chronic coughing
- Fatigue and weakness
- Unexplained weight loss
Pleural mesothelioma is often diagnosed in its later stages due to its nonspecific symptoms. Treatment options typically include a combination of surgery, chemotherapy, and radiation therapy. Early detection can significantly improve prognosis and quality of life.

Peritoneal Mesothelioma
Peritoneal mesothelioma develops in the peritoneum, the tissue lining the abdominal cavity. It is the second most common type, accounting for 10-20% of all mesothelioma cases. This form of cancer is caused by ingesting asbestos fibers, which become lodged in the abdomen, leading to inflammation and genetic mutations over time.
Common Symptoms of Peritoneal Mesothelioma
- Abdominal pain and swelling
- Ascites (fluid buildup in the abdomen)
- Loss of appetite
- Nausea and vomiting
- Weight loss
- Fatigue
Due to advancements in treatment, particularly Hyperthermic Intraperitoneal Chemotherapy (HIPEC) combined with surgery, many patients have seen improved survival rates. In fact, over 80% of patients undergoing this multimodal treatment live five years or longer.

Pericardial Mesothelioma
Pericardial mesothelioma is a rare and aggressive form of cancer that forms in the pericardium, the thin membrane surrounding the heart. It accounts for less than 1% of mesothelioma cases and is one of the most challenging types to diagnose and treat due to its proximity to the heart.
Common Symptoms of Pericardial Mesothelioma
- Chest pain
- Irregular heartbeat (arrhythmia)
- Difficulty breathing
- Persistent cough
- Fatigue
- Pericardial effusion (fluid buildup around the heart)
Diagnosing pericardial mesothelioma often involves imaging tests, echocardiograms, and biopsies. While treatment options are limited, they may include surgery to remove the pericardium, chemotherapy to shrink tumors, and palliative care to improve quality of life.

Why Understanding Mesothelioma Types Is Important
Each type of mesothelioma presents unique challenges in terms of diagnosis, treatment, and prognosis. Understanding these differences allows patients and caregivers to:
- Identify symptoms earlier for faster diagnosis.
- Access specialized care and treatments tailored to the mesothelioma type.
- Make informed decisions about clinical trials and emerging therapies.
Our goal is to provide you with the resources you need to navigate this complex disease. Whether you or a loved one is affected by pleural, peritoneal, or pericardial mesothelioma, understanding your specific diagnosis is the first step toward effective care.
If you have been exposed to asbestos or are experiencing symptoms related to mesothelioma, consult a medical professional immediately. Early detection and proper treatment can significantly improve your outcome.
