Mesothelioma is an asbestos related disease. It is a form of cancer that can surround an organ in the body. It can surround the whole area of a lung when it has already developed to a malignant Mesothelioma. It may also be mistaken as lung cancer when this happens because the symptoms are similar. However, it can be prevented. Companies dealing with asbestos can provide information to their employees when there is a risk of asbestos exposure. They can help their people live a healthy lifestyle and protect them from the cancer that may develop through their work.
