I was told i had ground glass area in my left lund after an mri and that they are usually cancerous....is this true. i have so many problems that i am just about ready to be put out to pasture permanently?

Ground glass appearance in a section of lung can be caused by cancer but also by infection,fluid collection or partial collapse ( atelectasis). I recommend having your physician asking the radiologist if a CT scan guided needle biopsy of the area in question is feasible or whether consultation with a pulmonologist or chest surgeon should be the next step.
