@chris, welcome to Mayo Connect. I'd like to ask you a few questions. Who told you that ground glass isn't dangerous? Have you recently been diagnosed with lung cancer? Do you have symptoms at all?
Ground glass is an appearance on a CT of a cluster of lung cells that have changed. It can be, and often is, a precusor to lung cancer. Usually adenocarcinoma of the lung. I do not know if this type of cell change shows up anywhere else.
