What are the Causes and Risk Factors of Mesothelioma
Mesothelioma is a rare cancer that develops in the mesothelium, the thin layer of tissue that lines the inside of the chest, abdomen, and pelvis. The most common cause of mesothelioma is exposure to asbestos, a mineral that was once widely used in construction and other industries. Asbestos fibers are small and can be easily inhaled and sometimes swallowed. Once they are inside the body, they can become trapped in the mesothelium and cause inflammation and damage. Over time, this damage can lead to the development of mesothelioma cancer.
Settings for Exposure
Asbestos exposure can occur in a variety of settings, including:
Occupational exposure: Workers in certain industries, such as construction, mining, and shipbuilding, are at high risk of asbestos exposure.
Environmental exposure: People who live near asbestos mines or processing plants may be exposed to asbestos fibers in the air.
Secondary exposure: People who live with or work around someone who is exposed to asbestos may be exposed to asbestos fibers through secondhand exposure.
The risk of developing mesothelioma increases with the amount and duration of asbestos exposure. People who have been exposed to high levels of asbestos for a long period are at the highest risk. However, there is no safe level of exposure to asbestos. Even a single exposure can increase the risk of mesothelioma.
Mesothelioma can take many years to develop after asbestos exposure. The average latency period is 30-50 years. This means that someone who is exposed to asbestos in their 20s may not develop mesothelioma until they are in their 50's, 60's, or 70's.
Increased Risk Factors
Radiation, genetics, and the SV40 Virus may increase the risk for mesothelioma:
Radiation exposure: Exposure to high levels of radiation, from nuclear accidents or from thorium dioxide which was sometimes used with X-rays during the 1920s and 1950s, may increase the risk of mesothelioma.
Genetics: Some people may have a genetic predisposition to mesothelioma which makes them more susceptible to developing the disease.
SV40 virus: The SV40 virus is a type of polyomavirus that has been linked to mesothelioma in some cases, although, the exact role is not fully understood.
How to Reduce Risk of Mesothelioma?
Mesothelioma is a complex disease, and the exact cause is not always known. However, asbestos exposure is the most common risk factor for mesothelioma, and steps can be taken to avoid exposure to asbestos if possible. If you have been exposed to asbestos, there are a few things you can do to reduce your risk of developing mesothelioma:
Get regular checkups: See your doctor for regular checkups and screenings, especially if you have a history of asbestos exposure.
Eat a healthy diet: Eating a healthy diet can help to boost your immune system and protect your cells from damage.
Exercise regularly: Regular exercise can help to reduce your risk of developing many types of cancer, including mesothelioma.
Avoiding radon exposure. Radon is a radioactive gas that can cause lung cancer. If your home has high radon levels, you can take steps to reduce your exposure.
Avoid new exposures: Have your home inspected for asbestos by a qualified professional.
Not Everyone Gets Mesothelioma
Remember that not everyone who has been exposed to Asbestos or who has additional risk factors will development Mesothelioma cancer of any kind. A qualified physician can help assess your risks for Mesothelioma and regular checkups can find it early when it is easier to treat.
