The main cause of mesothelioma is exposure to asbestos. This means that if you have not been working around any asbestos, then you do not have to worry about catching mesothelioma.  However, if you worked in the construction industry, particularly between the1940s and 1970s, then it is important that you identify this particular workplace and find out if they were using asbestos. Keep in mind that if your loved ones worked in a place with asbestos, you are also in danger of having mesothelioma because of exposure to the particles and fibers of asbestos left on their skin, clothes, and hair. Also, if you worked in a building where asbestos was used, you are at risk of having mesothelioma. Remember that even if the company you worked for was not aware of the risk of asbestos causing cancer, you still have the ability to take part in a lawsuit against that company in order to deal with your medical bills and the expenses of your loved ones and family.Over 75% of the cases of mesothelioma are due to asbestos exposure. While there has been a medical study trying to link smoking and mesothelioma, it has shown that smoking does not increase the chances of mesothelioma. Don’t be fooled into thinking that smoking may have caused your mesothelioma – no studies have proven this connection.
