MESOTHELIOMA IN X-RAYS

Mesothelioma Cancer's Causes

Causes of Mesothelioma Cancer

The scientific and medical evidence has proven that the main and primary cause of malignant MESOTHELIOMA is exposure to ASBESTOS. The exact method by which asbestos causes mesothelioma is still NOT understood, but medical professionals have a number of theories:

1) Asbestos fibers enter cells and disrupt the function of cellular structures that are essential for normal cell division, causing cellular changes that lead to cancer.

2) Asbestos causes irritation and inflammation of mesothelial cells, which results in irreversible scarring, cellular damage, and eventually cancer.

3) Asbestos causes the production of free radicals. These molecules damage DNA, and cause cells to mutate and become cancerous.

The presence of asbestos causes cells to produce ONCOPROTIENS. These molecules cause mesothelial cells to ignore normal cellular division restraints, and this can lead to the development of cancer.

Asbestos results in cellular damage this is the fact that ties each theory together . This causes cells to lose control over normal cell cycles and results in uncontrollable division. Healthy cells follow cycles of cell division that ensure tissues do not grow and duplicate beyond normal conditions - in cancerous cells, these restraints are lost.

2. What is MESOTHELIOMA ?

Mesothelioma (cancer of the mesothelium) is a disease in which cells of the mesothelium become abnormal and divide without control or order. They can invade and damage nearby tissues and organs. Cancer cells can also metastasize (spread) from their original site to other parts of the body. Most cases of mesothelioma begin in the pleura or peritoneum.

1. What is the MESOTHELIUM?

The MESOTHELIUM is a membrane that covers and protects most of the internal organs of the body. It is composed of two layers of cells:
1 layer immediately surrounds the organ;
the other forms a sac around it.

The mesothelium produces a lubricating fluid that is released between these layers, allowing moving organs (such as the beating heart and the expanding and contracting lungs) to glide easily against adjacent structures.

The mesothelium has different names, depending on its location in the body.
The pericardium covers and protects the heart.The pleura is the membrane that surrounds the lungs and lines the wall of the chest cavity.The peritoneum is the mesothelial tissue that covers most of the organs in the abdominal cavity. The mesothelial tissue surrounding the male internal reproductive organs is called the tunica vaginalis testis. The tunica serosa uteri covers the internal reproductive organs in women.

F.A.Q. about MESOTHELIOMA

MESOTHELIOMA

Mesothelioma is a type of CANCER.It is a rare form of cancer in which malignant (cancerous) cells are found in the mesothelium,wich is a protective sac that covers most of the body's internal organs.
Most people who develop mesothelioma have worked on jobs where they inhaled asbestos particles.
