Asbestos and mesothelioma-Asbestos is main cause of mesothelioma cancer especially pleural mesothelioma. People exposed to asbestos have greater risk because while working they inhale asbestos particles. These asbestos fibers then trapped in between layer of mesothelia. Our body cannot eliminate these asbestos fibers. Those particles then initiate pleural cells to multiply uncontrollably. Due to this reason the pleural layer thickens and fluid accumulate at the space that is known as pleural effusion. This fluid then put pressure on lungs cause difficulties in breathing
