I have to go for a low dose CT scan July 9th. My doctor says they will do a series of three of them, so not to be alarmed. I hope I have good luck with this. It will be what it will be. I have 48 years of smoking behind me, it will be a miracle if they don't find anything. It was actually my Dr. that suggested it at my complete physical. I didn't even have to ask. Hoping all will be good.
