Mesothelium Cancer- Mesothelioma

What is mesothelioma?
Mesothelioma is a cancer of the mesothelium. This is a thin lining membrane of certain parts of the body, covering the outer surface of most of our body’s organs especially in the linings of the chest or abdomen. Cancer starts when cells start to grow in an abnormal growth, get out of control and become invasive. Cells in nearly any part of the body can become cancer.
Asbestos exposure mostly to people who have worked in industries and their families has been linked to the development of serious respiratory diseases and cancers, including mesothelioma, lung cancer, asbestosis, the asbestos-based materials which have been used, is the main cause of developing Mesothelium Cancer Mesothelioma.


What is the difference between endothelium and mesothelium?
Endothelial cells and mesothelial cells differ in location. As mention before covers the outer surface of organs, while Endothelium covers the inner surface of the blood vessels and other tube-shaped vessels.
1-The Endothelium;
Endothelium is a type of epithelium that lines the interior surface of blood vessels, lymphatic vessels, and the inner walls of the heart chambers providing a barrier between the blood and the rest of the body tissues.
2-The mesothelium:
The cavities within the body encompassing the chest, abdomen, and the space around your heart are surrounded by a layer of specialized cells called mesothelium or mesothelial membrane. Mesothelium /Mesothelial cells also cover the outer surface of most of your internal organs and assist in general organ functions. The mesothelium is particularly important to organs that are commonly in motion as the mesothelium helps protect your organs by releasing a special lubricating fluid between layers that allows free range of motion within the body and against each other. For example, the expansion and contraction mechanism of the lungs, stomach, or heart which needs this fluid to makes it easier for its movement inside their cavities.
The mesothelium has different names in different parts of the body:
• In the chest it’s called the pleura; it coats the lungs and the space in the chest containing the lungs.
• In the abdomen it’s called the peritoneum; it lines the inside of the abdomen and many of the organs in the abdomen.
• Around the heart it’s called the pericardium; it covers the heart and creates the space that holds the heart in the chest.
• The male internal reproductive organs called the tunica vaginitis; it lines the testicles.
• The internal reproductive organs of women called the tunica serosa uteri.
Each of these groupings of the mesothelium is extremely critical to the functions of the body structures which they encompass and the Mesothelium Cancer can start in any of these linings. Malignancies (cancerous tumors) occurring within the mesothelium membranes are called malignant mesothelioma, or simply mesothelioma. These cancerous tumors can be non-cancerous (benign) or cancerous (malignant) both are known to occur, but benign tumors of the mesothelium are much more rare than malignant mesothelium tumors.
What How Mesothelium Cancer- Mesothelioma Is Formed?
The cell is the basic building block of all living things and in condition it is formed by epithelial cells these cells in healthy conditions normally grow and divide (multiply) to replace old cells, but they can also be at risk of mutating upon their exposure to asbestos as they grows quickly and uncontrollably. The Healthy mesothelium cells of the body membrane can be easy influenced to the exposure of asbestos and adjust themselves easier than other cells and go abnormal growth, stick with each other resulting from uncontrolled cell growth and this process leads to the growth of tumors. Therefore, the metastasis process (the spread of a cancer) is not as fast as it could be when compared with other cells related to this condition.

How Common is Mesothelioma?
Between 2,500 and 3,000 new cases of mesothelioma are diagnosed in the United States each year but it is still a relatively rare disease. Because mesothelioma needs decays to be signified in health problems according to projections there is an incidence to expect a rise in the next decade. Mesothelioma is more common in men than in women and risk increases with age.
