4 Primary Types of Mesothelioma | Location, Cell Types & Malignancy

Mesothelioma Cancer and Primary Types of Mesothelioma 

Mesothelioma is the general term used for any type of cancer that occurs in mesothelioma, which is the tissue that surrounds important organs. There are different types of mesothelioma, while all forms of mesothelioma are the result of exposure to asbestos, a toxic chemical found in many places, there is more than one type of this form of cancer.

Here are 4 primary types of Mesothelioma

    • Peritoneal Mesothelioma
    • Pericardial Mesothelioma
    • Testicular Mesothelioma

Three Types of Mesothelioma Cells

There are three types of cells that compose mesothelioma tumors. Let’s see these three types of mesothelioma cells:


Types of Mesothelioma by Percentage

Let’s know about all these types of mesothelioma by their quantity percent that tells us how much each of these makes out of total cases.

Malignant Pleural Mesothelioma

    1. Pleural Mesothelioma: 75% of all cases
    2. Peritoneal Mesothelioma: 10-20% of all cases
    3. Pericardial Mesothelioma: 1% of all cases
    4. Testicular Mesothelioma < 1% of all cases

Pleural mesothelioma

Pleural lung mesothelioma is the most common type of mesothelioma, which is characterized by the formation of tumors in the pleura, which is the protective lining of the lung surrounding the thoracic cavity and the diaphragm.

Causes of pleural mesothelioma

Like other types of mesothelioma, pleural mesothelioma is also associated with exposure to asbestos. When asbestos fibers enter the body by inhalation, they accumulate in the pleura and begin to change their character after one or two decades.

These changes occur in the form of irritation and inflammation, which causes the formation and proliferation of cancer cells. Such phenomena lead to thickening of the pleura, which further aggravates the condition by accumulating fluid in the thoracic cavity.

The fluid that accumulates in the pleural cavity exerts pressure on the lungs and makes breathing difficult. At this stage, the patient feels that something bad is happening in the chest area, causing a problem in normal breathing and causing persistent pain and coughing. These types of mesothelioma, it is common.

Swelling of pleural mesothelioma

The different symptoms of pleural mesothelioma include:

    •  A persistent cough
    •  Durable chest pain.
    •  Formation of lumps in the chest area.
    •  Hemoptysis (a cough with blood)
    •  Dyspnea (shortness of breath)
    •  Dysphagia (difficulty swallowing)
    •  Lose weight
    •  Fatigue and fever.

Peritoneal Mesothelioma

Peritoneal mesothelioma is one among the different types of mesothelioma that occurs in 10% to 20% of all cases of mesothelioma. This types of mesothelioma develop in the peritoneum, which is a protective layer around the abdominal cavity and its organs. In peritoneal, peritoneal mesothelioma, cancer becomes inherently due to the rapid proliferation of cancer cells.

How does it induce mesothelial dementia?

But the question is: what causes the proliferation of cancer cells in the protective lining of mesothelium? The answer is ‘asbestos fibers’. Yes, exposure to asbestos, which causes the final formation of tumors in the interbellum (peritoneum).

Asbestos fibers penetrate the human body by inhalation or after ingestion and in close-ups of the peritoneum. Here, these fibers are trapped and there is no way out. After spending one or two decades, these fibers begin their destructive activity and cause changes in the nature of the peritoneum.

This change occurs in the form of irritation and inflammation, which then increases to produce cancer cells. After the formation of these cells, they begin to divide rapidly, which causes the thickening of the peritoneum and the formation of fluid around it.

As the number of fluid increases, it begins to press on the abdominal cavity and the patient begins to show symptoms such as persistent abdominal pain or the formation of lumps under the skin in the abdomen. In some other types of mesothelioma, the same thing takes place.

The symptoms of mesothelioma dementia

Several symptoms of peritoneal mesothelioma include:

  • Abdominal pain
  • Abdominal inflammation
  • Formation of lumps in the abdominal region.
  • Lose weight
  • Anemia
  • Fatigue
  • Nausea
  • Vomiting or fever.

Pericardial Mesothelioma

Pericardial mesothelioma is a dangerous condition of the heart that comes from cancer cells that accumulate in the lining of the heart. Comparable to the pleura and peritoneal mesothelioma, it is a fatal health problem due to the importance of the area in which it develops.

The main cause of pericardial mesothelioma is contacted with asbestos particles and fibers. For this reason, those who are more likely to inhale these life-threatening fibers, such as construction workers and asbestos manufacturers, are at risk.

People who have contact with these people also have a risk of this type of mesothelioma due to the fact that this group of people may have asbestos fibers attached to clothing or hair.

The indications for mesothelioma can vary from person to person. Common symptoms and warning symptoms include a continuous cough, coughing up blood, shortness of breath, chest pain and arrhythmias.

Other symptoms that may be affected by people are nausea, weight loss, waste and loss of appetite. These symptoms can be but not necessarily seen in other types of mesothelioma.

Testicular Mesothelioma

Testicular s means the testicles, so this form of the mesothelioma affects the tissues that are found in this part of the male body. This is the rarest form of the disease and, as such, there is not much information available about diffusion statistics or joint therapies. At this time, less than one hundred cases of this type of mesothelioma have been reported.

So these are the most common types of mesothelioma. We hope you got all the valuable information about all types of mesothelioma you should have.
