@felix536- Welcome to Mayo Clinic Connect. Good morning, it's nice to meet you. I am the Mentor for the Lung Cancer group for Mayo Connect. As members, we can only share our own health experiences, and are we not able to provide a medical diagnosis.

I'm wondering what brought you to the doctor. Were you coughing, spitting up blood, trouble breathing?

I have what is called multifocal adenocarcinoma of the lung. Simply put, this is when several ground glass lesions show up in one or both lungs. Mine started out with 3 lesions in my left upper lung. Then 3 years later a single one along the surgical line of that surgery. I also have a lower left lesion that is being watched with very little change in over 5 years.

I want to state that I do not know enough about all lung cancers to say that only multi-focal adenocarcinomas present this way.

What kind of doctor are you seeing for this? Has anyone considered doing a biopsy?
