Mesothelioma of the Pleura, Peritoneum, and Pericardium: Diagnosis and Treatment
When a tumor begins to grow from the mesothelium in the lining of the lungs, abdomen, or heart, it is a rare and aggressive disease. Mesothelioma is primarily associated with asbestos and can often masquerade as common diseases.
K+31 specialists provide accurate diagnostics and select treatment based on the location and stage.

Types of mesothelioma
The disease is classified by the lining of the lungs it affects. Symptoms, treatment, and prognosis depend on the location, so the types of mesothelioma are analyzed separately.
Pleural Mesothelioma
This tumor is the most common and affects the lining of the lungs. Pleural mesothelioma causes shortness of breath, chest pain, and pleural effusion; it is essentially a cancer of the pleura, closely related to asbestos. This type of pleural cancer remains undetected for a long time.
Peritoneal Mesothelioma
In the abdominal cavity, the disease behaves differently. Peritoneal mesothelioma develops in the lining of the abdomen and presents with bloating, pain, and ascites. When it spreads, it leads to carcinomatosis—multiple lesions throughout the peritoneum.
Pericardial Mesothelioma
The rarest form affects the pericardium. Pericardial mesothelioma disrupts heart function and causes shortness of breath, pain, and fluid accumulation around the heart.
Causes and risk factors
The main culprit of the disease is known, but it doesn't act immediately. Let's look at what increases the risk of developing this tumor, as mesothelioma rarely occurs without a cause.
Asbestos Exposure
The key cause is inhaling asbestos dust. The link between asbestos and mesothelioma has been proven: the fibers remain in tissues for decades and trigger the malignant process. The most dangerous are the finest fibers, which penetrate deeply into tissue and are almost never eliminated by the body.
Occupational Risks
Construction workers, shipyard workers, insulation workers, and anyone else exposed to asbestos in their work environment are at the highest risk. The risk persists for decades, and mesothelioma can manifest itself many years later.
Other Possible Factors
Less commonly, the disease is associated with previous chest radiation exposure and certain mineral fibers. Hereditary factors only slightly increase susceptibility, but even without them, mesothelioma is possible after exposure to asbestos.
Individual complaints are nonspecific, but a persistent combination of them is a reason for examination. You should consult a doctor if you experience the following symptoms:
- Shortness of breath
- Chest pain or heaviness
- Persistent cough
- Increased abdominal size
- Unexplained weight loss
- Increased fatigue
- Prolonged fluid accumulation in the pleural or abdominal cavity
A timely consultation with an oncologist helps to avoid wasting time and achieve a faster diagnosis.
General information
Mesothelioma Symptoms
Manifestations depend on which lining is affected and remain vague for a long time. Early symptoms of mesothelioma are easily mistaken for bronchitis, fatigue, or stomach problems.
Early Signs
Initially, weakness, mild shortness of breath, weight loss, and a low-grade fever are common. These mesothelioma symptoms are nonspecific, so the disease is often detected late.
Symptoms of Pleural Involvement
When the pleura is affected, shortness of breath, chest pain, and a persistent cough become increasingly common. Pleural mesothelioma compresses the lung and causes pleural effusion, and the pleural tumor gradually restricts breathing.
Symptoms of Peritoneal Involvement
Peritoneal involvement causes bloating, heaviness, and pain in the abdomen, along with an increase in its volume due to ascites. In this location, peritoneal mesothelioma is often accompanied by nausea, bowel disturbances, and weight loss.
Symptoms of Pericardial Involvement
Pericardial involvement causes heart pain, arrhythmia, and severe shortness of breath. Here, mesothelioma symptoms are especially dangerous: fluid around the heart interferes with its contraction.
How a Treatment Plan is Chosen
The program is put together by a team, not a single physician. Mesothelioma treatment is planned after the tumor type, stage, and patient condition are known, and the decision is made collectively.
Several factors influence the choice:
- Tumor location and extent
- Morphological examination results
- General condition and comorbidities
- Informed patient preferences
This results in personalized treatment, not a one-size-fits-all approach. The program is revised during follow-up examinations if the disease does not respond as expected.
Post-Treatment Monitoring
After the active stage, the disease is monitored. Follow-up includes regular checkups, CT scans, and tests to detect tumor recurrence early, as mesothelioma is prone to recurrence. The doctor determines the frequency of visits and the scope of monitoring individually, based on the initial stage and response to therapy.
Advantages of contacting our oncology center
This type of disease is managed by a team: an oncologist discusses mesothelioma with a surgeon, a chemotherapy specialist, and a radiologist. At our center, the patient experiences the entire process in one place:
- Comprehensive diagnostics without wasting time
- Consultation and morphological verification
- Modern methods of antitumor therapy
- Post-treatment support and monitoring
This format saves weeks and increases the accuracy of every decision regarding mesothelioma. The patient doesn't have to collect reports from different doctors themselves—everything is stored in a single medical record.
The key differences between the three forms are conveniently summarized in a table:
| Type | Location | Main symptoms | Diagnostic methods | Treatment methods |
|---|---|---|---|---|
| Pleura | Lung lining | Shortness of breath, chest pain, cough | CT, MRI, pleural biopsy | Surgery, chemotherapy, and immunotherapy |
| Peritoneum | Abdominal cavity | Distension, pain, ascites | Ultrasound, CT, laparoscopy | Systemic therapy, HIPEC |
| Pericardium | Pericardial sac | Heart pain, shortness of breath | Echocardiography, MRI | Chemotherapy, pericardiectomy |
Quote from a doctor:
"In our practice, accurate morphological diagnosis of mesothelioma is crucial. Only after a comprehensive examination and case discussion at a consultation do we formulate an individualized treatment plan that takes into account the stage of the disease, the patient's general condition, and current antitumor therapy options," says an oncologist.

What is mesothelioma?
This is the name given to a malignant tumor that develops from the mesothelium—the thin membrane lining:
This is a rare oncological disease, and malignant mesothelioma grows along the surface of the membranes rather than as a single nodule. In oncology, this tumor is considered difficult to detect.
Characteristics of the disease
The disease develops slowly and may manifest itself decades after exposure to asbestos. However, mesothelioma quickly spreads through the membranes and causes effusion—a collection of fluid in the cavity. The latency period between exposure to asbestos and the first symptoms often reaches thirty to forty years, which is one of the reasons for its late detection.
How does mesothelioma differ from other cancers?
Unlike typical tumors that grow in a nodule, this tumor spreads in a sheet and completely envelops the membrane. This is why malignant mesothelioma is difficult to diagnose early and requires a special approach.
