Mesothelioma Cancer – An Overview

Mesothelioma is a rare form of cancer which affects people who have worked on jobs where they inhaled asbestos particles. In this type of cancer malignant cells are found in the mesothelium, a protective sac that covers most of the internal organs of the body. The cells of the mesothelium become abnormal and divide without control or order. These abnormal cells can invade and damage nearby tissues and organs. They also spread to other parts of the body. In most case the disease begins in the pleura or peritoneum, which covers most of the organs in the abdominal cavity.

There has been a rise in the incidence rate of mesothelioma cancer in the past 20 years. It is found mostly in men than women and the risk increases with age. In spite of this can appear in either men or women at any age. In 70 to 80% of the cases, exposure to asbestos is the reason for the disease. Asbestos is the name of a group of minerals that occur naturally. They appear as masses of strong, flexible fibers that can be separated into thin threads and woven. Due to its special qualities it is widely used in industries. If tiny asbestos particles float in the air, especially during the manufacturing process, they may be inhale or swallowed by the workers causing serious health problems. Apart from mesothelioma exposure to asbestos increases the risks of lung cancer, asbestosis and other cancers such as those of the larynx and kidney.
