Mesothelioma in Situ: The Earliest Stage of a Deadly Disease
Mesothelioma in Situ: The Earliest Stage of a Deadly Disease What is Mesothelioma in Situ? When you think of mesothelioma, you likely picture an aggressive and invasive cancer with a poor prognosis. But what if we could catch it at the earliest stage—before it becomes invasive? That’s where mesothelioma in situ (MIS) comes in. Mesothelioma in situ (also called atypical mesothelial proliferation) is a newly recognized pre-invasive stage of mesothelioma. Researchers and pathologists believe that this earliest form of the disease could be the key to understanding how mesothelioma develops—and how to stop it before it becomes deadly.
