Mesothelioma Medical Definition

Mesothelioma is a type of cancer that develops from the thin layer of tissue that covers many of the internal organs (known as the mesothelium).

Mesothelioma Medical Definition …what is Mesothelioma … To define Mesothelioma; Mesothelioma is a malignant tumor of the Mesothelium. To define Mesothelium; we can say that the Mesothelium definition is about a layer of cells (epithelium) that cover the outer surface of certain areas of the body. These serous cavities and certain body internal organs are within the Mesothelium to be protected while doing their functions. The mesothelium cells line most of the body’s internal organs. Mesothelium function is to protect these internal structures and aid in their movement by lubricating them and avoid frictions. A cancerous (malignant) tumor is a type of cells that has the ability to invade regardless of where they originate.

Mesothelioma cells from the mesothelium create one or more nodules and grow progressively into the normal cell body resulting a number of medical problems. The destruction of the Mesothelioma cells from the mesothelium form a solid coating around these body internal organs that they protect and damage nearby tissues. These invaders or cancer cells can also spread (metastasize) to other parts of the body.

Because  Mesothelioma  is associated with exposure to asbestos. Thus, Mesothelioma is an asbestosis cancer that occurs most commonly in the chest cavity especially the lung and may be found less commonly in heart and abdominal organs. This layer, termed the mesothelium is a membrane that primary function is to provide a slippery, non-adhesive and protective surface of. The mesothelium is made up of mesothelial cells when they are affected by asbestos exposure, they no longer grow or behave normally.  These changes to the mesothelial cells cause malignant mesothelioma.


Different types of Mesothelioma;

There are different types of Mesothelioma depending on where they originate. These types are related to the Mesothelium different names. The mesothelium has different names in different parts of the body. Asbestos cancer types are where they are located the name, the name is defined. According Mesothelioma has different Types by Location and can start in any of these linings.

Mesothelium Different Names; 

Pleural Mesothelioma Cancer (Mesothelioma Lung Cancer);

The mesothelium that protective layer that sacs the lungs and the wall of the chest cavity is called the pleura. Mesothelioma cancer that starts in the pleura -in the lung- is called pleural mesothelioma. Mesothelioma lung cancer is the most common of all Mesotheliomas.

Peritoneal Mesothelioma (Abdominal Mesothelioma);

The peritoneum is the mesothelial tissue that covers the abdominal cavity. Mesothelioma Cancer cells that grow in the lining of the abdominal cavity is called Peritoneal Mesothelioma.

 Pericardial Rare mesotheliomas

Rare mesotheliomas;

Pericardial Mesothelioma (Malignant Heart Cancer);

This type of Mesothelioma is very rare. The pericardium is the lining that covers and protects the heart. Mesothelioma Cancer cells that grow in the lining of the pericardium is called Pericardial Mesothelioma.

Testicular Mesothelioma/ Mesothelioma of the tunica vaginalis testis;

The mesothelial membrane lining the testes is called the tunica vaginalis testis in the male internal reproductive organs. While the mesothelial membrane lining the testes of the female internal reproductive organs is called the tunica serosa uteri. Mesothelioma Cancer cells that grow in the membrane lining the testes is called Testicular Mesothelioma. This type of Mesothelioma is very rare too.

What is the Malignant mesothelioma Prognosis?

Mesothelioma prognosis depends on how often it is discovered and how aggressive the lesion is. Unfortunately, discovering this type of tumor is very difficult in its early stage. Unfortunately, asbestosis cancer prognosis is poor. Mesothelioma is a rare form of cancer, difficult to treat and has poor prognosis most cases.


Why mesothelioma is difficult to diagnose

Why mesothelioma is difficult to diagnose;

Malignant Mesothelioma can be very difficult to diagnose because many other diseases symptoms are similar to Asbestos Mesothelioma symptoms. Mesothelioma is always mistaken for an infection or a more common type of cancer. But it is extremely important recording the patient’s history of asbestos exposure. This may help on discovering mesothelioma with every routine checkup. Malignant Mesothelioma symptoms and signs can take long time to develop from 20 to 60 years, that is why it is always discovered in its late stages. 


Mesothelioma causes

Mesothelioma causes;

Asbestos is the main factor that can cause mesothelioma cancer and chronic respiratory diseases. After decades of mesothelioma asbestos exposure, the signs of malignant mesothelioma symptoms appear.

How do you get mesothelioma;

Exposure to asbestos fibers and asbestos containing material – inhaled or ingested – get trapped into the lungs causing fibrous tissue within the lungs. The changes of the type of cells lining the internal organs may go genetic changes that create cancer cells; Asbestos Cancer Mesothelioma.


How much Asbestos exposure does it take to get Mesothelioma?

How much Asbestos exposure does it take to get Mesothelioma?

An Asbestos exposure of as little as one or two months may result in mesothelioma cancer. But generally, in terms of Mesothelioma Asbestos risk; there is no clear line or safety level of Asbestos exposure. The greater the exposure to asbestos the greater the risk of developing Mesothelioma.
