Thank you so much for your reply..I also am a nonsmoker and my Pet Scan came back negative but advised that does not necessarily mean not cancer and all factors must be weighed..Did you have a pet scan prior to having this noducle removed and did it come back than positive...I am just nervous to have a middle lobe removed on the "maybe" its cancer as thoracic surgeon says 30 to 50% on previous CT as my breathing is only at 55/60% due to damage from being diagnosed with COPD when in fact it is now confirmed (4 years ago) it is Eosinophilic Asthma and treated with a biologic. Thank you
