spot on lung

Hello, Has anyone had to deal with a spot on their lung x-ray? I do not smoke nor do I have symptoms. What did you do? Who did you see? How did it effect your surgery? I'm scheduled for WLS on the 28th at Emory with Dr. C. Daniel Smith. I am so upset by this spot problem I can't even be terrified properly about my WLS surgery. I have a PET Scan on the 20th and my pre-op is on the 23rd. I would appreciate any positive encouragement or experience anyone could contribute. Jewell Munn [email protected]
