Types of Mesothelioma

What are the Types of Mesothelioma?

The four types of mesothelioma are:

  • Pleural (lungs)
  • Peritoneal (abdomen)
  • Pericardial (heart)
  • Testicular

The most common form of mesothelioma is pleural mesothelioma and it is formed in the thin protective lining of the lungs. The next most common type of mesothelioma is peritoneal, which forms on the thin protective lining of the abdomen. The two least common types of mesothelioma pericardial and testicular, they only make up about 2 percent of all mesothelioma diagnoses.


Pleural Mesothelioma

Pleural mesothelioma is the most common type and accounts for around 75 percent of all mesothelioma diagnoses. This cancer develops in the thin protective lining of the lungs. The symptoms of pleural mesothelioma may or may not include:

  • Difficulty breathing
  • Dry cough
  • Chest pain
  • Difficulty swallowing
  • Fever
  • Night sweats
  • Lethargy/Fatigue

As with all mesothelioma cancer, your treatment options are dependent on the stage of the pleural mesothelioma. If your pleural mesothelioma is in Stage I or Stage II, then your options for surgery and treatment are more favorable than if your pleural mesothelioma is in Stage III or IV. During later stages of pleural mesothelioma, the goal is to minimize symptoms and improve your quality of life.


Peritoneal Mesothelioma

Peritoneal mesothelioma is the second most common form of mesothelioma and accounts for around 20 percent of all mesothelioma diagnoses. This cancer develops in the thin protective lining of the abdomen. The symptoms of peritoneal mesothelioma may or may not include:

  • Pain in abdomen
  • Swelling in abdomen
  • Loss of weight
  • Vomiting/Nausea
  • Diarrhea
  • Constipation
  • Lethargy/Fatigue

As with all mesothelioma cancer, your treatment options are dependent on the stage of the peritoneal mesothelioma. If your peritoneal mesothelioma is in Stage I or Stage II, then your options for surgery and treatment are more favorable than if your peritoneal mesothelioma is in Stage III or IV. During later stages of peritoneal mesothelioma, the goal is to minimize symptoms and improve your quality of life.


Pericardial Mesothelioma

Pericardial mesothelioma is one of the rarest forms of mesothelioma and accounts for around 1 percent of all mesothelioma diagnoses. This cancer develops in the thin protective lining of the heart. The symptoms of pericardial mesothelioma may or may not include:

  • Heartbeat irregularity
  • Pain in the chest
  • Coughing
  • Breathing difficulty
  • Fever
  • Night sweats
  • Lethargy/Fatigue

As with all mesothelioma cancer, your treatment options are dependent on the stage of the pericardial mesothelioma. Unfortunately, pericardial mesothelioma is usually only found in the later stages of cancer. A surgery to remove a tumor near the heart is extremely difficult and risky.


Testicular Mesothelioma

Testicular mesothelioma is a very rare form of mesothelioma and develops in the thin protective lining of the testicles. Less than 1 percent of all mesothelioma cases are testicular mesothelioma. The symptoms of testicular mesothelioma may or may not include:

  • Lumps on the testicle
  • Scrotum swelling

As with all mesothelioma cancer, your treatment options are dependent on the stages of the testicular mesothelioma. Surgery to remove the tumor is generally prescribed for patients if the testicular mesothelioma is in an early enough stage.


What Type of Mesothelioma is the Most Common?

Mesothelioma is a rare type of cancer, but it is extremely aggressive and will spread quickly in the body. This is why it is imperative that mesothelioma be diagnosed in early stages so that it will not spread. The most common type of mesothelioma is pleural mesothelioma and accounts for around 75 percent of all mesothelioma cases. The next most-common type is peritoneal mesothelioma and it accounts for around 20 percent of all mesothelioma cases. Pericardial and testicular mesothelioma account for 1 percent or less of all mesothelioma diagnoses.
