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.
