After attending seminar session which deals with cancer .
Then I get an explanation of cancer as well as photographs of cancer patients :(
They must be suffering from cancer when age 10th .
Cancer is always caused by exposure to asbestos called mesothelioma .
Its a protective layer that covers most of the organs .
The most frequent and common is the pleura . Pleura is the outer layer of the lungs and internal chest wall . And can occur in the peritoneum ( abdominal cavity membrane ) , heart , pericardium ( the sac that surrounds the heart ) .

Mesothelioma discussed there are 3 , that is :
  1. Pleural Mesothelioma : Occur in the lining network around the lungs .
  2. Peritoneal Mesothelioma : Occurs in network that line the stomach .
  3. Pericardial Mesothelioma : Occur in the lining network around the heart .
It was explained that there are several factors that could cause mesothelioma cancer , that is :
~ Exposure to asbestos : Asbestos is a mineral that is found in the environment . People who work in an environment contaminated with asbestos have a much greater risk mesothelioma .
~ Dust : Ingested dust will settle in the lungs or in the stomach and can cause irritation . 

For prevention is said to keep away from the place which contained asbestos , smoke , and dust pollution .
Hopefully recover quickly to cancer patients in the world :(
