I agree with @jonijean, you need to see a Pulmonologist, and be sure it is one with focus on lung cancer...because Specialists have subspecialties...one needs the professional with real knowledge.
Your situation illustrates the importance of following one's test results and advocating for ones 'self. Medicine is a broad subject, no doctor has knowledge of it all, it is up to the patient to be sure that there is follow-up in the right directions.
