mesothelioma and mesothelium

First,all you need to know is understand the mesothelium in order to understand the mesothelioma.

Mesothelioma- cancer that couse pain and death ( cancer of mesothelium )
Mesothelium - layers, membrane or lining that covers internal organs like lungs, heart or our moving organ. This protective layers is thin and consist of lubricating fluid to make sure our moving internal organ not injured while doing their daily process.

There are 2 layers of mesothelium.The mesothelial cells inside mesothelium keep produce the lubricating fluid to supply suitable condition between the 2 layer. That why we never feel pain when our heart moving every single second. Is is like oil engine that cover piston in our car engine. so simple right..Can you imagine what will happen if the cells stop releasing the fluid that surround our heart? It could be hell for every single air come inside heart.I just can't explain the feel in details coz i never affected by this cancer. i hope not!
