Mesothelioma: Symptoms and Treatment
Mesothelioma is a rare but aggressive form of cancer that primarily affects the lining of the lungs, abdomen, or heart. Understanding its causes, symptoms, stages, and treatments is crucial for early detection and effective management.
What is Mesothelioma?
Mesothelioma is a type of cancer that develops in the mesothelium, a thin layer of tissue that covers most internal organs. It most commonly affects the pleura (the lining of the lungs), but it can also occur in the lining of the abdomen (peritoneum), heart (pericardium), or testicles (tunica vaginalis).
Types of Mesothelioma
- Pleural Mesothelioma: The most common type affecting the lining of the lungs.
- Peritoneal Mesothelioma: Occurs in the lining of the abdominal cavity.
- Pericardial Mesothelioma: Affects the lining around the heart.
- Testicular Mesothelioma: Rare, occurring in the lining of the testicles.

Get A Second OpinionCauses of Mesothelioma
The primary cause of mesothelioma is exposure to asbestos, a group of minerals composed of microscopic fibers that were once widely used in construction, insulation, and other industries. When asbestos fibers are inhaled or ingested, they can become lodged in the mesothelium, causing inflammation and genetic damage over time.
Other Risk Factors
While asbestos exposure is the leading cause, other factors can contribute to the development of mesothelioma:
- Genetic Predisposition: Some individuals may have a genetic susceptibility to mesothelioma.
- Radiation Exposure: Previous radiation therapy to the chest or abdomen may increase risk.
- Zeolites: Minerals chemically related to asbestos, such as erionite, can also be a risk factor.
- SV40 Virus: Some studies suggest a link between the simian virus 40 and mesothelioma, although this is not conclusively proven.
Symptoms of Mesothelioma
Mesothelioma symptoms can vary depending on the type and stage of the disease. Common symptoms include:
Pleural Mesothelioma Symptoms
- Chest pain
- Shortness of breath
- Persistent cough
- Unexplained weight loss
- Lumps under the skin on the chest
Peritoneal Mesothelioma Symptoms
- Abdominal pain and swelling
- Nausea and vomiting
- Changes in bowel habits
- Unexplained weight loss
Pericardial Mesothelioma Symptoms
- Chest pain
- Heart palpitations
- Difficulty breathing
- Fatigue
Testicular Mesothelioma Symptoms
- Swelling or mass in the testicles
Diagnosing Mesothelioma
Diagnosis of mesothelioma involves several steps, including imaging tests, biopsies, and blood tests.
Imaging Tests
- X-rays Can reveal abnormalities in the chest or abdomen.
- CT Scans : Provide detailed images of the affected area.
- MRI: Offers a more detailed view of the tissues and organs.
- PET Scans Help determine the extent of the cancer's spread.
Biopsies
A biopsy is essential for a definitive diagnosis. Types of biopsies include:
- Needle Biopsy: A needle is used to extract tissue samples.
- Thoracoscopy: A small camera is inserted through the chest to obtain tissue samples.
- Laparoscopy: A camera is used to examine and take samples from the abdomen.
- Mediastinoscopy: Used to examine and sample lymph nodes.
Blood Tests
Blood tests can help identify biomarkers associated with mesothelioma, although they are not definitive on their own.
Stages of Mesothelioma
Mesothelioma is classified into four stages, which help determine the severity and spread of the disease.
Stage 1
- Cancer is localised to one area.
- Symptoms are mild or absent.
- Surgical removal is often possible.
Stage 2
- Cancer begins to spread to nearby tissues.
- Symptoms become more noticeable.
- Surgery, chemotherapy, and radiation may be considered.
Stage 3
- Cancer has spread to regional lymph nodes and surrounding tissues.
- Symptoms are more severe.
- Treatment focuses on managing symptoms and slowing progression.
Stage 4
- Cancer has metastasised to distant organs.
- Symptoms are severe and widespread.
- Treatment is palliative, focusing on quality of life.
Treatment Options for Mesothelioma
Treatment for mesothelioma depends on the type, stage, and overall health of the patient. Standard treatment options include:
Surgery
- Extrapleural Pneumonectomy: Removal of the affected lung, part of the diaphragm, and surrounding tissues.
- Pleurectomy/Decortication: Removal of the lining of the lung and chest cavity.
- Cytoreductive Surgery: Removal of as much of the tumour as possible, often combined with heated chemotherapy.
Chemotherapy
Chemotherapy uses drugs to kill cancer cells or stop them from dividing. It can be administered systemically or directly into the affected area (intracavitary chemotherapy).
Radiation Therapy
Radiation therapy uses high-energy beams to target and kill cancer cells. It can improve outcomes when combined with surgery and chemotherapy.

Immunotherapy boosts the body's immune system to fight cancer. Drugs like pembrolizumab and nivolumab have shown promise in treating mesothelioma.
Clinical Trials
Participation in clinical trials can provide access to new and experimental treatments that are not yet widely available.
Conclusion
Mesothelioma is a challenging and complex disease, but understanding its causes, symptoms, and treatment options can empower patients and their families to make informed decisions. Early detection and a multidisciplinary approach to treatment can improve outcomes and quality of life.
By staying informed and working closely with healthcare professionals, those affected by mesothelioma can navigate this difficult journey with greater confidence and hope.
