What is Mesothelioma?

Alright, so a lot of you are wondering why I have a post on this. Story is, a family member of mine was just diagnosed with Meso, and I just wanted to spread some information out there to others about what it is. Mesothelioma is a lethal form of cancer that attacks the thin layer of cells surrounding the lungs, heart, and abdominal cavity. Because the first symptoms appear decades after initial exposure to asbestos, mesothelioma is often diagnosed in late stages.
