Thank you for all your comments. I have had a couple of conversations with Mayo here in Scottsdale. They have all my info and know who to contact for previous scans and Xrays. It seems my file will first go to a specialist to look at the nodule and decide if they want to see me now or wait for a second CT scan in a few months to see if anything has changed and basically come up with a plan over the phone although I did share with them that my sister passed away from lung cancer last year at 68 so that might get someone's attention. Second stop for my file will be a Doc who specializes in the BE issue (look at me using abbreviations already). I'm guessing that's more likely where I will get my first appointment (fingers crossed). I'm reading what I can about airway clearance. Is it OK to start this before I see a doctor? Can I even get the hypertonic saline without an RX? Seems Amazon may not be the recomended resource.
