Most people have heard of both mesothelioma and lung cancer, and many assume that they’re the same thing. However, this is a common misconception. Both lung cancer and mesothelioma can be caused by asbestos exposure, and they present themselves with almost identical symptoms. However, they are entirely different diseases.
Mesothelioma is a rare form of cancer that is caused by exposure to asbestos. It takes years, often decades, for mesothelioma to develop after a person has been exposed to asbestos. That means there are still cases of this aggressive cancer which is caused by asbestos exposure from decades ago. The only way to know for sure if you have mesothelioma is through a doctor's diagnosis.
