Most people with malignant mesothelioma have worked on jobs where they breathed asbestos. Others have been exposed to asbestos in a household environment, often without knowing it. To learn more about the different ways in which people have been exposed:

How much exposure does it take to get the disease?
An exposure of as little as one or two months can result in mesothelioma 30 or 40 years later.

How long does it take after exposure for the disease to show up?
People exposed in the 1940s, 50s, 60s, and 70s are now being diagnosed with mesothelioma because of the long latency period of asbestos disease.

What is the prognosis for mesothelioma?
Like most cancers, the prognosis for this disease often depends on how early it is diagnosed and how aggressively it is treated. Click on Treatment Options to find out more about traditional and new approaches.
