The element that ties each theory together states that asbestos induces cellular damage, which causes cells to lose control over their own cycles of normal division and begin dividing uncontrollably. Healthy cells follow cycles of cell division that ensure tissues and organs do not grow beyond normal size; in cancer cells, these restraints are lost.
In cases of mesothelioma, the result is that membranes in the affected location begin to thicken, and fluid builds up in the spaces between membrane layers. As cancer cells continue to divide and pile on top of one another, tumors begin to form. The end result of uncontrolled division of cancer cells is that the function of the body’s organs and systems are impaired, due to factors such as internal pressure caused by the growth of tumors, and the reduction of availability of essential nutrients for organs.
Are There Any Other Causes of Mesothelioma?
The answer to this question is a simple “no.” Doctors and research scientists have not been able to determine any other causes of mesothelioma other than asbestos exposure. They do know, however, that smoking can aggravate a less serious asbestos-related disease, such as asbestosis, and prompt the formation of tumors and the onset of mesothelioma. Those who have been exposed to asbestos on a regular basis are advised not to smoke.
