What is Mesothlioma?

Causes of Mesothelioma

Cancers, including mesotheliomas, occur when the DNA in cells is damaged. DNA is the chemical in each of our cells that makes up our genes – the instructions for how our cells function.

We usually look like our parents because they are the source of our DNA. But DNA affects more than how we look. Some genes control when cells in the body grow, divide into new cells, and die.

Changes in these genes may cause cells to grow out of control, which can lead to cancer.

Asbestos exposure is the main cause of pleural mesothelioma. About 8 out of 10 people with mesothelioma have been exposed to asbestos.
