What Kind of Cancer is Mesothelioma: Understanding the Different Types

Rate this post

Discover the different types of cancer associated with mesothelioma. Understand what kind of cancer is mesothelioma and its impact on the body.

Mesothelioma is a rare and aggressive form of cancer that affects the mesothelium, a protective membrane lining various organs in the body. This disease is primarily caused by exposure to asbestos, a harmful mineral that was widely used in construction and industrial processes until its ban in many countries. In this article, we will delve into the various types of cancer associated with mesothelioma, shedding light on the distinct characteristics, symptoms, and affected areas. By gaining a comprehensive understanding of these different types, we can contribute to raising awareness and promoting early detection and treatment.

Understanding Mesothelioma

Mesothelioma is a complex disease that requires a thorough understanding to effectively combat it. This cancer primarily affects the mesothelial cells, which are responsible for producing the lubricating fluid that allows organs to move smoothly within the body. The most common cause of mesothelioma is exposure to asbestos fibers, which can be inhaled or ingested. Asbestos fibers are notorious for their ability to lodge in the lining of organs, leading to inflammation, genetic damage, and eventually the development of cancerous cells.

Early diagnosis of mesothelioma is crucial for effective treatment. However, due to its long latency period, symptoms may not manifest until several decades after exposure to asbestos. Common symptoms include chest pain, shortness of breath, persistent cough, abdominal pain, and unexplained weight loss. If you suspect any asbestos exposure or experience these symptoms, it is vital to consult a healthcare professional promptly.

Types of Mesothelioma

Pleural Mesothelioma

Pleural mesothelioma is the most common type, accounting for approximately 80% of all mesothelioma cases. It affects the lining surrounding the lungs, known as the pleura. Asbestos fibers inhaled into the lungs can irritate the pleura, leading to the development of cancerous cells. Symptoms of pleural mesothelioma include chest pain, persistent cough, difficulty breathing, and fluid buildup in the chest, known as pleural effusion.

Peritoneal Mesothelioma

Peritoneal mesothelioma affects the lining of the abdominal cavity, known as the peritoneum. It is the second most common type of mesothelioma, comprising roughly 20% of cases. Asbestos fibers can reach the peritoneum through ingestion or migration from the lungs. Symptoms of peritoneal mesothelioma may include abdominal pain, swelling, loss of appetite, nausea, and changes in bowel habits.

Pericardial Mesothelioma

Pericardial mesothelioma is an extremely rare form of mesothelioma, accounting for less than 1% of cases. It affects the lining surrounding the heart, known as the pericardium. The exact cause of pericardial mesothelioma is still not fully understood, but asbestos exposure is believed to be a potential factor. This type of mesothelioma often presents with symptoms such as chest pain, heart palpitations, difficulty breathing, and persistent cough.

Testicular Mesothelioma

Testicular mesothelioma is the rarest form of mesothelioma, accounting for less than 1% of cases. It affects the lining of the testes, known as the tunica vaginalis. The exact cause of testicular mesothelioma is still unclear, but it is believed to be linked to asbestos exposure. Symptoms may include swelling or a mass in the testes, pain, and fluid accumulation in the scrotum.

Mesothelioma and Cancer

Mesothelioma is unequivocally classified as a type of cancer. Cancer is a broad term used to describe the abnormal growth of cells that invade and destroy surrounding tissues. In the case of mesothelioma, the cells lining the mesothelium become cancerous and start to multiply uncontrollably. These cancerous cells can invade nearby tissues and spread to other parts of the body, a process known as metastasis.

While mesothelioma shares some characteristics with other types of cancer, its distinct behavior sets it apart. Mesothelioma cells have the ability to spread rapidly across the mesothelium, forming tumors and causing significant damage. Due to the aggressive nature of mesothelioma, early detection and treatment are crucial for improving patient outcomes.

Frequently Asked Questions (FAQs)

Can mesothelioma spread to other parts of the body?

Yes, mesothelioma can metastasize and spread to other parts of the body. Although mesothelioma primarily affects the lining of specific organs, such as the lungs or abdomen, cancerous cells can invade nearby tissues and travel through the lymphatic system or bloodstream to distant sites.

How is mesothelioma diagnosed?

Mesothelioma diagnosis typically involves a combination of medical history evaluation, physical examination, imaging tests (such as X-rays, CT scans, or MRIs), and tissue biopsies. A biopsy is the most definitive diagnostic method, involving the removal and examination of a small sample of tissue to determine the presence of cancerous cells.

Are there any effective treatment options available for mesothelioma?

While there is no known cure for mesothelioma, various treatment options can help manage the disease and improve patient quality of life. These options may include surgery, chemotherapy, radiation therapy, immunotherapy, and targeted therapy. The choice of treatment depends on several factors, including the stage of the disease, the patient’s overall health, and individual circumstances.

What are the survival rates for mesothelioma patients?

Survival rates for mesothelioma vary depending on several factors, including the type and stage of the disease, as well as the patient’s overall health and response to treatment. Unfortunately, mesothelioma is often diagnosed in advanced stages, leading to lower survival rates. However, advancements in treatment options and early detection strategies have shown promising results in improving survival rates and extending life expectancy.


In conclusion, mesothelioma encompasses various types of cancer that affect different linings within the body. Pleural, peritoneal, pericardial, and testicular mesothelioma each present unique characteristics and symptoms. Understanding these different types is vital for early detection, prompt treatment, and improved patient outcomes. By raising awareness about mesothelioma and its association with cancer, we can better support affected individuals and contribute to ongoing research efforts for more effective treatments. Remember, if you suspect any asbestos exposure or experience symptoms related to mesothelioma, consult a healthcare professional for proper evaluation and guidance.
