Bob, I too have had increased uptake in the nasal area and in the adenoidal area, and it was interpreted as inflammation from seasonal allergies.
I have had numerous nasal scopes, and they are absolutely NOTHING to worry about.....do it now! I certainly would!
I have recently been blowing bits of blood also, and when I looked in my nose with my trusty little flashlight, I noticed that the nasal septum is very inflamed, and the tissue is very friable.....bleeds at the slightest touch. I had it checked....twice..and was told that my septum is slightly deviated, so that the air hits it more directly than it does on the other side and keeps it inflamed (I went a week or so imaginging what THAt surgery was going to be like, since I just KNEW that it was more cancer!) He said that I might always have the inflammation. I wonder what this is going to look like on my next PET scan!
I sure do hope you get a pleasant surprise, but you asked, and yes, I have had some nasal inflammatory uptake observed on each of my scans. I hope that's all yours is, but I would ask them to scope you NOW, instead of waiting for six months. The scope is very benign.
