Mesothelioma is a rare and aggressive form of cancer that primarily affects the mesothelial tissues lining the lungs, abdomen, heart, and testicles. It is caused by exposure to asbestos, a mineral that was widely used in construction, shipbuilding, and other industries during the 20th century. Unfortunately, mesothelioma has a poor prognosis, and treatment options are limited.In this article, we will explore the various types of mesothelioma and provide you with an in-depth understanding of each. By the end of this guide, you will be equipped with the knowledge to identify the different types of mesothelioma and make an informed decision on how to manage the disease.
The Different Types of Mesothelioma: An Overview
There are four primary types of mesothelioma, which are classified based on the location and type of cancerous cells.
Pleural Mesothelioma
The most common form of mesothelioma is pleural mesothelioma, which affects the lining of the lungs. This type of mesothelioma accounts for around 75% of all identified cases. Pleural mesothelioma symptoms include shortness of breath, chest pain, coughing, and fatigue. Treatment options include surgery, radiation, and chemotherapy.
Peritoneal Mesothelioma
Peritoneal mesothelioma affects the lining of the abdomen and accounts for approximately 20% of mesothelioma cases. Symptoms of peritoneal mesothelioma include abdominal pain, bloating, and bowel changes. Treatment options include surgery, chemotherapy, and immunotherapy.
Pericardial Mesothelioma
Pericardial mesothelioma affects the lining of the heart and is the rarest form of mesothelioma, occurring in less than 1% of cases. Symptoms of pericardial mesothelioma include chest pain, heart palpitations, and difficulty breathing. Treatment options are limited, and palliative care is often recommended.
Testicular Mesothelioma
Testicular mesothelioma is the rarest type of mesothelioma, with approximately 100 cases reported worldwide. This form of mesothelioma affects the lining of the testicles and can cause swelling and pain in the affected area. Treatment usually involves surgery to remove the affected testicle.
A Closer Look at Each Type of Mesothelioma
Pleural Mesothelioma
Pleural mesothelioma is caused by the inhalation of asbestos fibers, which become lodged in the lining of the lungs. Over time, these fibers can cause inflammation, scarring, and eventually, cancerous tumors to form. Pleural mesothelioma is often difficult to diagnose, as symptoms may not appear until decades after initial exposure to asbestos.
There are two primary subtypes of pleural mesothelioma, which are differentiated based on the type of cancerous cells present.
Epithelioid Pleural Mesothelioma
Epithelioid pleural mesothelioma is the most common subtype and is characterized by the presence of epithelial cells. These cells are relatively slow-growing and respond well to treatment, making this subtype of mesothelioma more responsive to therapy.
Sarcomatoid Pleural Mesothelioma
Sarcomatoid pleural mesothelioma is a less common subtype and is characterized by the presence of sarcomatoid cells. These cells grow rapidly and are less responsive to treatment, making this subtype of mesothelioma more difficult to manage.
Peritoneal Mesothelioma
Peritoneal mesothelioma is caused by the ingestion of asbestos fibers, which become lodged in the lining of the abdomen. Over time, these fibers can cause inflammation, scarring, and eventually, cancerous tumors to form. Peritoneal mesothelioma is often difficult to diagnose, as symptoms may not appear until decades after initial exposure to asbestos.
There are three primary subtypes of peritoneal mesothelioma, which are differentiated based on the type of cancerous cells present.
Epithelioid Peritoneal Mesothelioma
Epithelioid peritoneal mesothelioma is the most common subtype and is characterized by the presence of epithelial cells. These cells are relatively slow-growing and respond well to treatment, making this subtype of mesothelioma more responsive to therapy.
Biphasic Peritoneal Mesothelioma
Biphasic peritoneal mesothelioma is characterized by the presence of both epithelial and sarcomatoid cells. This subtype is more difficult to manage, as the treatment response can vary depending on the proportion of each type of cell present.
Sarcomatoid Peritoneal Mesothelioma
Sarcomatoid peritoneal mesothelioma is a less common subtype and is characterized by the presence of sarcomatoid cells. These cells grow rapidly and are less responsive to treatment, making this subtype of mesothelioma more difficult to manage.
Pericardial Mesothelioma
Pericardial mesothelioma is caused by the inhalation of asbestos fibers, which become lodged in the lining of the heart. Over time, these fibers can cause inflammation, scarring, and eventually, cancerous tumors to form. Pericardial mesothelioma is often difficult to diagnose, as symptoms may not appear until decades after initial exposure to asbestos.
Testicular Mesothelioma
Testicular mesothelioma is the rarest form of mesothelioma, and little is known about its causes and risk factors. Most cases occur in men over the age of 60, and the disease is often misdiagnosed as testicular cancer. Treatment typically involves surgical removal of the affected testicle, followed by chemotherapy or radiation therapy.
