EXPOSURE TO ASBESTOS: THE MAIN RISK FACTORS OF MESOTHELIOMA


Asbestos is a mineral that is found naturally in the environment. Asbestos fiber is strong and resistant to heat, making them useful in a variety of devices, such as insulation, brakes, shingles, flooring and many other products. When the mineral asbestos is lost, for example when the mining process or when removing asbestos insulation, dust will usually be formed. If the dust is inhaled or swallowed, the asbestos fibers will settle in the lungs or in the stomach, this precipitation cause irritation that can cause mesothelioma. How the irritant then developed into mesothelioma is not understood with certainty. It should be about 30 to 40 years or more for mesothelioma to develop after a person is exposed to asbestos exposure. Most people exposed to asbestos for a long time are less likely to develop mesothelioma. However, most people who experience short exposure actually develop the disease. This suggests that other factors may be involved in the development of mesothelioma in a person. For example, someone inherited predisposition to cancer or some other condition that may increase the risk of mesothelioma.
The risk Factors that may increase the risk of mesothelioma include:
 • Never or frequent exposure to asbestos. If you have been exposed to asbestos fibers directly at the workplace or at home, it will increase the risk of mesothelioma.
• Live with someone who worked in the asbestos environment. People exposed to asbestos fibers can bring home on their skin and clothing. Exposure to these fibers for many years can put a family at risk for mesothelioma. People who work with asbestos high levels can reduce the risk of asbestos fibers brought into the home by way of showering and changing clothes before they go home from work.
• A monkey virus used in polio vaccine. Some studies suggest a link between mesothelioma and simian virus 40 (SV40), a virus originally found in monkeys. Millions of people may have been exposed to SV40 when receiving polio vaccinations between 1955 and 1963 because the vaccine was developed using monkey cells. Having in mind that the SV40 linked to certain cancers, the virus was removed from the polio vaccine. Whether SV40 could increase the risk of mesothelioma or not is still being debated, and further research is still needed. Complications When pleural mesothelioma spreads in the chest, this condition will put pressure on the structures around the area. It can lead to complications, such as:
• Difficulty in breathing
• Chest pain
• Difficulty swallowing
• Swelling neck and face caused by pressure on the large vein, the vein leading from the upper body to your heart (superior vena cava syndrome)
• Pain caused by pressure on the nerves and spinal cord
• Accumulation of fluid in the chest (pleural effusion), which can compress the lungs and make breathing difficult person
