How Does Mesothelioma Affect the Body?

Rate this post

Mesothelioma, a rare and aggressive cancer, has become a significant concern due to its association with asbestos exposure. Understanding how mesothelioma affects the body is crucial for early detection, diagnosis, and effective treatment. In this article, we will delve into the various aspects of mesothelioma, its impact on different organs, symptoms to watch out for, and address frequently asked questions surrounding this disease.

Understanding Mesothelioma

Mesothelioma is a cancer that affects the thin tissue lining of organs, known as the mesothelium. It is primarily caused by inhaling or ingesting asbestos fibers, which become lodged in the mesothelium, leading to abnormal cell growth. There are three primary types of mesothelioma: pleural (affecting the lungs), peritoneal (affecting the abdomen), and pericardial (affecting the heart). Understanding these distinctions is crucial for comprehending how mesothelioma impacts the body.

Effects of Mesothelioma on the Body

Mesothelioma and the Lungs

Pleural mesothelioma is the most common form, affecting the lining of the lungs. As the tumor develops, it causes inflammation, fluid buildup, and thickening of the pleura. This can lead to symptoms such as chest pain, persistent cough, shortness of breath, and fatigue. The tumor can spread to nearby tissues, making it essential to detect and treat it in its early stages.

Mesothelioma and the Abdomen

Peritoneal mesothelioma affects the lining of the abdomen, known as the peritoneum. The tumor growth in this area can lead to abdominal pain, swelling, changes in bowel habits, and weight loss. As the cancer progresses, it may spread to the liver, spleen, and other abdominal organs, causing further complications.

Mesothelioma and the Heart

Pericardial mesothelioma, though rare, affects the lining around the heart, called the pericardium. This type of mesothelioma can cause chest pain, irregular heartbeat, difficulty breathing, and fluid accumulation around the heart. Due to its location and potential impact on cardiac function, pericardial mesothelioma requires immediate medical attention.

Other Organs Affected by Mesothelioma

While the primary types of mesothelioma focus on specific regions, the cancer can spread to other organs as it advances. Metastasis can occur in distant sites such as the liver, kidneys, and even the brain. Understanding the potential impact on these organs is crucial for comprehensive mesothelioma management.

Symptoms and Signs of Mesothelioma

Mesothelioma symptoms can vary depending on the type and stage of the disease. However, there are common signs to be aware of:

  • Persistent cough or hoarseness
  • Shortness of breath or difficulty breathing
  • Chest or abdominal pain
  • Fatigue and weakness
  • Unexplained weight loss
  • Swelling or lumps in the abdomen

Due to the nonspecific nature of these symptoms, diagnosing mesothelioma can be challenging. It is often mistaken for other respiratory or gastrointestinal conditions. If you have a history of asbestos exposure or experience any of these symptoms, it is vital to consult a healthcare professional for a thorough evaluation.

FAQ about Mesothelioma

Q: Is mesothelioma always caused by asbestos exposure?

A: Yes, asbestos exposure is the primary cause of mesothelioma. However, there have been rare cases where individuals with no known asbestos exposure have developed mesothelioma. Other potential causes are still being researched.

Q: What are the treatment options for mesothelioma?

A: Treatment options for mesothelioma include surgery, chemotherapy, radiation therapy, and emerging treatments like immunotherapy and targeted therapy. The choice of treatment depends on various factors such as the stage of the disease and the patient’s overall health.

Q: Can mesothelioma be cured?

A: While mesothelioma is a serious and often aggressive cancer, advancements in treatment have improved survival rates. However, a complete cure is challenging to achieve due to late-stage diagnoses. Early detection and a multidisciplinary treatment approach offer the best chances of long-term survival.

Q: Can I file a lawsuit if I have mesothelioma due to asbestos exposure?

A: Yes, individuals diagnosed with mesothelioma due to asbestos exposure may be eligible to file a lawsuit seeking compensation for medical expenses, lost wages, and other damages. Consulting an experienced mesothelioma attorney can help determine your legal options.


Understanding how mesothelioma affects the body is crucial for early detection, effective treatment, and improving outcomes for individuals diagnosed with this aggressive cancer. Whether it impacts the lungs, abdomen, or heart, mesothelioma requires prompt medical attention. If you have a history of asbestos exposure or experience symptoms associated with mesothelioma, do not hesitate to consult a healthcare professional. By raising awareness, promoting early detection, and advancing research, we can strive towards improved outcomes and a better quality of life for mesothelioma patients.
